This company is unreliable, overpriced and will find any and every excuse to take money from you. Their customer service is a joke. Not only is it nearly impossible to get ahold of their representatives; they are also highly unhelpful in trying to resolve any issues you will certainly encounter! Please for the love of all that is good and beautiful go anywhere else! They're outdated and unreliable devices are faulty at best. This company has bought and paid for their trustpilot reviews. Check out their 5 star reviews on trustpilot.com You'll clearly see the overwhelming positive 5 star reviews are fake and paid for. No sane person would ever write such positive reviews for a company that's extorting people every penny they can. read more

Agree it's a shame you can not leave a zero stars. The only positive reviews are on the website and through Trust Pilot. After recalls to them in 20 minutes and getting three different answers, I started recording the phone calls. I have three final calibrations. The first one came up with a violation that I knew could not have happened but decided to suck it up and just wait out the time. It felt like it was more energy to fight it and just to deal with than the additional time and energy to argue. With my Second final calibration, it came back compliant. However, because my drivers license had expired, they had added 45 days from the date of which I got my due license. The state of Tennessee issued for 45 days which would have ended on January 27. Customer service told me it was 49 days which would have ended on January 30. Very convenience because that is when the next buy must be billing occurred. Once again, I felt like the three extra days wasn't worth the argument and it takes the complaints to department three days to respond assuming they do respond. My final straw occurred with the third final calibration after the 45 days, that compliance reviewed back with a violation that was two months for the original violation. Fortunately, my car was in the body shop in maintenance mode. I called and got the exact time of the violation. Thing called body shop, which provided The with the timeline of the bodywork and when they were completed with it, which happened to be 30 minutes after the alleged violation occurred. I asked for a review with the state which meant I had to send a form to the company. I called back to have them. Tell me the violation of heard six minutes after the completion of the work. The problem here was that the battery was dead when I picked up the car and I a lot of body shop 15 minutes after the second time they gave me. Fortunately, I was able to pull my call from my cell phone where I had called them twice to report the problem which was there was a power interruption due to the battery. And a sync error. The customer service rep tell me that my car was successfully started 30 minutes before the battery was replaced and argued that it stayed running for a given amount of time. I had a 3 1/2 hour drive from the body shop to my home. They are keeping being about the change of the time. I was able to contact Body shop to have them send an email to me about the issue with the car, not starting that day until the battery was replaced 30 minutes after they closed, which was an hour after the violation. If you want to really be able to document your issues log into your account from a laptop or iPad and do a live chat and then screenshot the conversation. After the phone call with customer service rep. That I recorded. Four hours later, I am engaged in a live test session and was told about the two errors and when I specifically asked about the violation of tampering with the device because the camera was obstructed, I was informed it was not a violation, and the view was not a instructed because the camera was upside down and after I started the car, I turned it right side up. I have documented all of this and sent it to the state of Tennessee. Additionally, if you go to Reddit you will see that a law firm in Knoxville is engaged in a lawsuit. The Better Business Bureau has them listed with an a rating under the company that owns Intoxalock which is Consumer Safety Technology LLc. I have reported down, asking them how they have an a rating given the mention reviews between here and Reddit. People are having the same complaints. I have heard nightmares from people in person about the problems when it comes to getting this device removed. Their intention is to prolong the length of time you have this device to continue collecting bimonthly payments. They are taking advantage of people, knowing that after several months that most people cannot prove or documents, the incorrect information. Take the phone to put them on speaker and I told you this conversation or engage in live chat and the conversation. Also anytime that you blow and it comes out with a reading other than zero take a picture of it. iPhones are awesome for date and. Timestamps. One other issue, which is the original violation they came off with stated a reading that is way higher than anytime I've blown. I also documented on this day that they changed the time of the violation and included the act of violation. My car was not started. I pointed out to them that I had pictures taken before and after the violation from two different locations proving that was started and I left. They came back with the car was started later. This is something I've also documented. There needs to be another class action suit against this company. I will be contacting the law firm that I found and calling one that is local to where I live. They need to be shut down. read more

If I could leave one start I would. Nothing but bad experiences with this. Customer service is a joke. They put you on hold, hang up on you and lie. The device failed and left me stranded. I had to tow it to get calibration and the Indian guy say call AAA and tell them to tow it to the calibration place. He didn't give me any policy numbers for Intoxalock. They had to change the device. After 210 bucks later I got my car towed and calibrated. I called them back and now they are saying you have to get the driver of the tow truck signed then send an email. I emailed the receipts for the tow truck and the Lyft. Go with a different company! No one really wants to help you there. read more

If I could give less than 1 star I would. Terrible service, terrible device. Schedule my removal and took it to the service center and Intoxaloc never scheduled so I'm stuck in it another week and have to pay another payment. Good luck getting a hold of anyone at intoxaloc. Total scam, don't don't do it. read more

Garbage company, nothing but problems and extra fees all the time, I parked and went into grocery store and came out to a violation because it asked me to blow when I was in store, car was off, keys in my hand and still asking me to blow when im not even in car lol not fair and costing me way more money than should read more

The customer service is awful! They do not answer the phone and transfer all over the place. No one takes ownership or accountability. They try and sell you the serivce and rush you to any install place even if its not that close to your home. NEVER USE THIS COMPANY. You will be on hold and transfered all over the world with no resolution. read more

Device just stopped working. Slept in my car at a gas station 50 miles away from my home. Called intoxalock and they said they couldn't do anything. I explained my situation and of course the Indian was laughing under his breath. Finally the morning hit and I towed my car to my place $400, I called intoxalock again and they said they would put in a work order to get a whole new device. I told them I have work and I can't wait of course the Indian woman was laughing again. read more

Again , absolute terrible experience, hand held device has an issue, told them for few days , 5 out of the 6 people I spoke to were a complete waist if time, a 6 year old would know better, one hung up on me, told me it could be 5 days before i can get an inspection, I run a company that does 24/7 service, i already lost a full day, they going to pay me what I lost? They charged me for a lock out that had nothing to do with me! This company does not care about their customers, I know 3 other people with this device, anytime Intoxalock is mentioned, they go nuts, they have the same bad experience. Again im stranded outside a customer's house because this company' incompetence, no regard for customer's and they don't care. I have already spoken to a lawyer about this and will proceed with it. Again iv to get a tow , Disaster. read more

The absolute worst SCAM company ever! Reported violations for their unit being defective! Drains your battery every day! read more

HORRIBLE EXPERIENCE! I have a brand new Mercedes and the device displays a violation 40 every few days for the last 2.5 months. I have had to continue returning to the service center to have inspection after inspection done. The entire device has been replaced, multiple relocations of wires, etc. NOTHING WORKS. I've spent so much time and energy on this thing while still continuing to pay my monthly fees. They don't know what they're doing and their devices along with customer service are the worst I've ever experienced. read more

Customer service is in India I can assume since every call (6) i have made ive talked to someone with a heavy indian accent. Some were nice but they seem to deflect your questions by just going off a script it feels like. The last person I talked to that prompted this review was someone unprofessional. He sounded like he just woke up and he was rushing me off the phone like he needed to leave. Didn't ask if I had any other questions, basically just said okay there's an answer for you, bye. My question was answered but I'm sick of the unprofessionalism . Fees are atrocious read more

Unfortunately, yelp has not generated a zero star option yet. The fortunate part is that everything is on a recorded and monitored line. Supervisor Leslie who was very adamant about not finding my account, clearly told me more than enough times that I did not have an active account with them. Even after providing her my account number she still stated that I didn't have an active account. Mysteriously, she finds my account after she said to me that her and I were having a language barrier when it's clear simple English "You do not have an account". The entire phone call she maintains a horrible stank attitude and I quote "I DONT CARE" coming from Leslie's "language barrier". She never got back on the phone and hung up. Leslie's poor attitude is a violation and liability to the company and should be removed from her position immediately. Additionally, I signed a lease that obligates Intoxalock to send me a 30 day notice of any price changes and they failed to do so. read more

I recommend shopping around and finding a provider other than Intoxalock. Their device is very sensitive on re-tests and will regularly register as insufficient breathe. This means you then pay them various fees to get it unlocked and serviced through no fault of your own (other than picking the wrong provider). They also ding you hard for recalibration tests. I'm due to have my device removed and a calibration falls a week before this. DMV told me the recalibration can be waived if Intoxalock will do so. They said no they won't allow that. They wan to extract another fee from me apparently. Go with another provider. One star for customer service and value. read more

Court ordered to have this device installed, fees not included, for 6 months. It is 52$ every two weeks (there are devices that are way cheaper so shop around). The first failure came when the truck was not running, forced to pay Intoxalock 80$ (they have a camera and refused to look at footage at the time and date they were accusing of) and the Specialist 40$ to reset device. 2nd failure came when truck was parked at husband's job, he was out in the field, and they gave 3 separate times there was a failure on this morning...still refused to investigate camera footage. Paid 80$ and 40$ again because what else could I do? Truck is no longer working, the program is over, towed truck to Specialist to remove device, device removed for 75$, towed home. Received notification from Intoxalock that we didn't pay this month's fee. The program ended a month ago, truck hasn't moved and was also told that there was another failure, given truck hasn't moved from the same spot in weeks. Intoxalock is ran by con-artist who take advantage of court ordered situations. When you call to try to speak to them about their lies and accusations, they lay on the foreign accent so thick that you end up hanging up. Use anyone else but Intoxalock, unless you love problem after problem and giving away money. read more

horrible experience with this company nothing but problems since day one killed my battery they charge fees for everything and service ce they sent me to to have device installed had not a clue what they were doing they messed my vehicle up.. then when trying to get ahold of customer service they put you on hold for hours then when you get someone they barely speak English and are hard to understand an supervisors are very disrespectful and rude so I finally told them remove device and then they started adding all these fees.. nothing but headaches I believe this company is nothing but a scam DO NOT USE THIS COMPANY PLEASE read more

After waiting 45 minutes on hold, I took the opportunity to look up customer reviews. Reading repeated complaints about failing devices and poor customer service confirmed my decision to end the call and look for alternatives. I do not understand why answering a call should take more than 10-15 minutes, yet I was left waiting three times that long. The experience almost suggests that after every weekend, half the population receives a DUI. Thank you, Intoxalock, for the delay--it gave me the chance to learn more about your reputation. One star below because zero stars was not an option!) read more

Do not use these clowns!!!! Called them a month ago to send my compliance data to my state. Then called again 2 weeks later to make sure they sent it and was told it was sent the day I called the first time. Went to get my unrestricted license yesterday and the state hadn't received the compliance data from them. So I call to have it sent again and ask them to attach my email to the email they send (so I know that they actually send it) and was told they couldn't attach my email. Called back today and was told that the email was sent. Then they tell me that they send the email to their own compliance department then that department sends it to the state. OK so I ask to talk to someone from that department and was told that department only handles emails so there is no one to talk to. OK then let me talk to a supervisor and was told " I will not let you speak to a supervisor". So here I am paying for something that should have been removed a month ago. DON'T waste your time and money with them. Find a different company. The person at my DMV doesn't recommend them to anyone because they are always like this. Liars and cheats! read more

DO NOT USE THEM UNLESS YOU WANT TO BE SCAMMED AND PAY OUT OF POCKET FOR THEIR SYSTEMS FAILURE. I have spent about 3,000$ extra of my own money to pay for their mistakes since getting this. They are making me pay hundreds of dollars for their failed systems. Their systems went down and twice I went in to be in compliance. They said they would give an extension, they didn't. My car was forced to be towed as a result of their failure, they didn't reimburse it. Now my car is inoperable, I am not required by law to have their ignition lock, and they refuse to activate it and let me drive to a service center to get it removed. They are forcing me to pay my own money to tow my car because of their systems failure. I have spent 20+ hours on hold trying to call them because their online website for support is broken and doesn't have my correct social to verify my information. The sheer amount of immediate electrical problems I've had the day of install is staggering. Customer service will leave you on hold for an hour only to try to tell you they can't do anything, and after you get letters of authorization from your state authorizing them, they will still tell you to go **** yourself and hang up. Get literally any other ignition interlock service if you have to. read more

DO NOT USE THIS "company"!! Initial staff is nice, very helpful, makes you feel like you'll never have an issue of getting help when needed. As soon as you get your device installed, and I'm not kidding - down to the second, you'll never have access to that team again. Everything is on an outsourced line. In desperation (after they charged me almost $150 and couldn't tell me why) I used someone else's phone to try and get back to the initial team so that I could get to the bottom of everything. The lady asks for my phone number so she can "look up my account".....she then proceeds to go silent for about a minute and the line transfers over to the SAME OUTSOURCED team I'm already on the other phone with! I hand up and try to call back only to realize she's added the phone number that I've called from (not associated with my account at all) to some list that routes directly to the outsourced team. This company is predatory and will take money without authorization then give you no explanation, no help, no hope of keeping money in your account l, and will do everything in their power to keep this device in your car as long as possible so they can take every dollar you have. Go ANYWHERE else. read more

Absolutely diabolical scam. I'd rather have 4 YEARS of LifeSafer than 4 months of Intoxalock. Excessive and unpredictable fees charged to your account almost every 1-2 weeks, ridiculous calibrations not even included in the "lease" costs, unreliable service going down with no degree of compensation (you actually pay MORE to get LESS), clueless and useless customer service, constant device issues and frustration. Avoid drinking and driving for THESE REASONS ALONE, but if you must get an interlock you should be GRATEFUL that LifeSafer exists to actually make things reasonable. read more

One of the worst devices ever created in the history of mankind. If you want additional punishment to your charge, look no further. This device will have you pulling out your hair, eyes and teeth. You have to blow out, in, out and if you don't do it perfectly each time the machine will count it as an error. It is the most annoying thing in the world. I wasted $500 or more installing and returning (had to disconnect it myself because I couldn't get the car to start) this Godforsaken device. Go with LifeSafer Interlock instead read more

Don't do intoxalock. Their prices are triple what they advertise. Charge you for all this elective stuff without asking. I had to pay 400 to install the thing. The device looks like it's used and immediately gave me issues. Got the car home and then next day couldn't start it. Had 3 people try n still couldn't get it. Finally the next day I get it and I get a retest but device wouldn't work. Tried for a half hour n nothing. Finally said eff it and turned car off and now am in a lockout and being extorted 100 dollars to get out of it. I'm trying to get it Uninstalled now cuz I'm not paying 100 dollars everyday for violations. They giving me issues tho. Don't do it. Ull regret it. If u have to try smart start. They originally offered me much lower rates but the shop is so far and I went to intoxalock. Biggest mistake ever. Going to just wait it out a year n not drive read more

Yet here we go again. I've been with Intoxalock for almost two years. After the last issue (which they finally resolved after months) here we are yet again. My lease ends on January 19th and even though I am indigent I am still required to pay the fees... despite it being part of the issue from last time where I paid the fees and after months they finally gave me back a refund (on their account of course, getting it fully refunded was like pulling teeth) So I called and was told multiple times that I was not allowed to speak to a supervisor or be transferred to a different department. I am yet again beyond frustrated with this horrible company and out of more money than it's worth. just take the no driving. you'll be saving money and time! Adding this because what the heck??!! Received paperwork stating I needed to sign a new lease. Looked it over and exited so I could call after work. My lease is in place until my uninstall date on the 19th...or should have been Got a notification on my phone that my new lease was signed but I didn't sign anything!!! So again... DO NOT GO WITH INTOXALOCK!!! read more

Horrible Horrible. money stealing. i dont even drink anymore. they almost didnt stop charges for a bad blower handheld. i had to go to the service center. and they had to fight for me. theyve lied multiple times. im changing to lifesafer. i could go on and on about this group of thieves. Ive spent so much money on false blows on the device. this last one. there was a pizza in the passenger seat. i blew and failed. 4 minutes later i blew and passed. the service center had to fight to get them to give me a new handheld and not charge me. But truth is all their handheld devices are this way. i know because ive been down this road twice. the one time intoxalok said they would wipe charges after i paid to recalibrate the device. i called back to have them wipe charges and they wouldnt do it. said they record the calls and if they checked the call they would remove the charge if i was told that. charge was never removed. CORRUPT! CORRUPT! read more

Drains battery. Bran new battery and in less than a year it dies! Charged me to start the car after battery was replaced They say it's a 50 $ charge every 2 weeks ends up being around 65 The customer service is not helpful at all Be prepared to have more troubles in the future with false retest and also a bit hard to use I would not recommend this to anyone Go to smart start or any other company other than intoxalock They do not work with you with recalabation or communicat with the shops that are closed on the weekends Do not do not do not go with this company read more

horrible company beware! i have been eligible for removal of device with a written email to intoxalock from probation department and they refuse to approve removal. predatory business tactics to keep you paying expensive lease rental fees every 2 weeks. beware do not use this company they will not respond to your emails either customer service is all overseas. they will not care about your needs and give you attitude over the phone. use a different company intoxalock is the worst one. read more

Do not get your interlock from this company. They have horrible equipment and terrible customer service. A business filled with trickery read more

no stars. Unbelievable the myriad of ways they have gotten things wrong for me. They directed me to install the wrong equipment and made my installer jump through hoops to return the equipment that had to be pulled. I tried to get the right equipment sent to the installer but found it may take 8 days to communicate with their removal department and their customer service personnel before they would send the right equipment to install, this after they had promised they could send it overnight so I could have it installed quickly. Every time you call, you get different answers to the same questions leading you in circles. I had to call repeatedly because they kept telling me they would ship it overnight but we could see the tracking number and it never got picked up by the shipping company they use. Even after 3 days of calling, it never shipped. As if we would not notice that it did not get shipped overnight, as promised, again and again. I had to give up and switch to smart start and am so pleased that I made the switch. Smart start is awesome. Its machinery is tiny and easy to use compared to the huge box that intoxalock is using. And intoxalock is hard to blow into, many many repeated attempts are necessary to get a reading. I hate their machinery and love smart starts'. I was so very nervous about intoxalock because even they made it clear that the machinery may drain your car battery, leaving you stranded and I was always worried about that. I hope there is not permanent drain on my battery, but for all I know, I may need a new battery sooner than I would if I had not used intozalock. Make the switch and give yourself one less thing to worry about. I wish I could give no stars. read more

Supposedly, Intoxalock sent in my final 120 day compliance review to TN. I had them electronically send it again because TN said they did not get it. Once again, they TN does not have it. Instead, I finally find out from TN that they sent my final calibration in but sent no Certificate of Compliance. WTH. You know this is required. Stall. Stall. Oops. Stall. Did Intoxalock mistake it for toilet paper? Between the two entities this is double poo. They both will do ANYTHING to prolong this process in order to net more money. If they do a monthly calibration check then there should BE NO REASON for a final calibration anyways. No violations in TWO YEARS. Keep it simple...after final calibration & no violations- just sent it in automatically and have State stamp their approval on it. Why do that when there is more money to take?? SMH. Shame on Intoxalock for milking people and lieing. read more

I had an Intoxalock device installed in my 2013 Volvo S60 on September 2, 2025. Within two weeks, the device drained my battery and damaged my starter. My car would randomly turn on accessories, unlock doors, activate the parking brake, and turn lights on and off by itself. Eventually, the car became completely disabled and would not start, even after replacing the battery. I have not been able to use my vehicle since September 15, 2025. I followed Intoxalock's instructions, purchased a new battery on October 30, 2025, and had the car towed to a recommended shop on November 1, 2025--the same day as my scheduled recalibration appointment. After waiting over 90 minutes, I was told the car still would not start, and that Intoxalock's recalibration department is not open on weekends (which I was never informed of). The shop also stated they receive frequent complaints about Intoxalock. Each time I contact Intoxalock, I receive inconsistent information, severe language barriers, and no resolution. At one point, a representative even added my neighbor's number to my account instead of returning my call. Despite replying to my online review, no one from Intoxalock has contacted me directly to resolve this issue. Intoxalock has falsely implied I tampered with the device, which I absolutely did not do. My vehicle had no mechanical or electrical problems prior to installation. Now it is completely non-functional, and I am being told I must pay for towing, repairs, and removal of a defective device that caused the damage to begin with. There are numerous similar complaints nationwide, which shows this is not an isolated incident. I am requesting removal of the device at no cost, reimbursement for damages, and restoration of my vehicle to working condition. read more

I would highly not recommend intoxlock. My device kept killing my battery and even when you put it in sleep mode. Still drained my battery. In the winter I could never start my car. It took me 30 to 40 mins to warm it up. Smart lock is the best route to go. There fees are high. Paying 46 every 2 weeks plus 50 for calibrations. And customer service you can't understand the employees they all have deep accents. It took me 2 weeks to get my interlock out . Because the paper work even tho I had a vailed driver license again and proof. They will do everything in there power to keep that interlock in your car to make money. Never in my life I will use intoxlock again or get another DUI. I highly suggest going to different company where you can remove the device from your car and take it inside like smart lock for the winters. read more

The absolute worst predatory service ever. The whole year Ive been on Ive paid 3 times what the price was supposed to be for violations that were very ridiculous. I also was to be finished with this program on March 13th and today I still have a system in my car. Now the contract wasn't renewed and now my truck doesn't work and I have until Monday morning or I'll be terminated from my place of employment. I was given a number to text since all their numbers are down. No one will send my Declaration of Compliance. So even tho I have served my sentence here I am still on and no one from Intoxalock will even respond to me. Absolutely try another service. This company is vicious from start to finish. Even the people are nasty. Thanks Intoxalock! read more

My vehicle has been at my designated garage for 2 weeks waiting to be worked on for mechanical issues. I reported my vehicle as being repaired which apparently is only good for 5 days. please recognize that my vehicle is still at the garage, waiting to be worked on. I've tried calling to explain but Intoxalock makes it literally impossible to speak with someone and charges me while not on the road. Customer service is terrible...non existent.. read more

I am suppose to have this device removed but can't because company is currently shut down. Extremely rude customer service. There is no option for current customers to speak to a representative so you have to call off a different number or blocked number then choose option as new customer. read more

Decietful and predatory business practice from sales to their legal department. A quick search on Facebook or Google could have saved me so much hassle, potential issues with device and billing and specifically the installation of an incorrect device and lying Social Media Specialist operating as a retention expert but with the same bait and switch tactics as their sales representatives. Do not install a device voluntarily, or to satisfy legal requirements for your state as Intoxalock/Consumer Safety Technology LLC has a countless number of claims and lawsuits. Use RoadGaurd or LifeSafer read more

These people are horrible over the phone they will try and scam you out if your money. Read the reviews on this place and it says it all. DO NOT USE THEM! I luckily cancelled before I installed the machine and was horrified. Trying to get thru to someone is a nightmare and when I cancelled the lady Kristina actually hung up the phone on me! DO NOT DO NOT DO NOT USE THEM!!! If you need someone out of Kansas use SPEEDY BONDS HALLIE is her name and she is great. The install is easy and quick and everything is done right at there shop. Intoxalock is a nightmare do yourself the favor and don't waste your time or money! read more

Customer service terrible, device failure too common, and very unsanitary. Any other reviews that are positive are most likely AI or false claims. read more

Horrible service since I've had intoxaloc, they have made me late or miss out on work multiple occasions with issues with the device and there miscommunication within there own company causing nothing but time and money at our own expense. Not to mention tryna get help from someone on the phone, takes literally and hour each time just to try to get a hold of someone, and you better pray there nice cause sometimes there just plain rude and will drop your call to make life even harder than it has to be with them read more

TERRIBLE!!!!! DO NOT USE THIS COMPANY!!!! Negative stars if possible They will steal from you and lie. Had to fight for 3 different charges to be removed from my bill. They double bill you for EVERYTHING. Claim you can contact them 24/7, yet the app has an email link that takes 3-5 days for a reply. How does that help someone whose car will not start? I wish I had done more research on this but I was under a deadline and went with the first company I saw. BIGGEST MISTAKE OF MY ADULT LIFE!! I thought the courts gouged me but these lowlifes are worse! read more

Now they have suspended my license due to two lockouts ,from false readings ,pump failure,it got so bad for last two months it would take me five times of blowing to get it to take a reading multiple times failed start then 30 seconds later passed ,finally they had changed device and cord twice and still false readings. Now license is gone I have received removal documents from RMV and sent to them as directed and nothing after 3 different times on phone wasting hours and I couldn't understand representative now I can't even get the thing removed . It's beyond me how this company is still in business absolutely ruined my life . read more
