Utah, my car wouldn't re-start. Not a lock- out but a device malfunction. I am a female and was stranded on the side of the road 50 miles from the nearest town. I had stopped to pull over to look at a feature on the side of the road and then tried to restart. After passing, turn the key and nada - device reads "wait to restart" with a 3 min countdown. This happened over and over again. Then, I call and I am on hold - mind you, still stranded on the side of the road. I'm on hold for at least 30 minutes and the "person" I spoke to told me that I could get a tow 15-30 miles and to keep the receipt. I explained to this person that would not work, I am 50 miles from the nearest town and hours from my service center. Then I asked to speak with a supervisor. She said yes, it was a malfunction of the blower. We did a few things and somehow got it working and I could get home. There were a few more issues after that but issues seemed to resolve themselves. This was 5/17. Then today, 5/30, I am on my way out of town to see my son - 4 hour drive. On the way out of town, I stopped to get my blower calibrated. Well, my car is still at the dealership. After being calibrated, the car would not start. My vacation was cancelled, I won't get to see my son graduate, all because Intoxalock devices suck. Also, despite the fact that I got it calibrated there, there was no technician available that could look at it or fix it. Now, I've been stuck multiple times in dangerous situations because the device malfunctioned. I live in a rural area and was just lucky that I had a friend who was close to where my car was at the dealership. If she would not have been there, I would've had to take an Uber for an hour to get back home. My battery is fine. These are not lockouts, these are purely device malfunctions. Use any other company! I have heard they are all bad and meant to inconvenience you. The devices are mechanically flawed and every mechanic I've spoken to who has to work on cars with them agrees. Additionally, I've been on hold for over an hour - you cannot get help!!! Still on hold - 2 hours, 3 hours....also, this is an intoxalock issue, I am in no way talking about the dealership. Now, after being without a car, missing a day of wok, having to cancel my trip.... Intoxalock has the audacity to tell me it's my fault and a problem with my car. They refuse to replace the device in any way or help me! read more

This company is TERRIBLE!! I keep getting these damn violations of unauthorized starts of my vehicle and I am not even in my car! The shit will happen when I am working my 12 hour shifts!! Then when I call they keep fucking charging me and saying I have to take it in to get inspected. They told me if it is my car they will charge me but if its the device then they will pay for it. They clearly see how often i get these violations and wont do shit about it! They are not helpful and try to take your money! I have literally damn near gotten over 15 violations of the same thing when im not in my car to get these violations. It is ridiculous! I have to work long ass hours and I get a lockout after I get off work from my stressful nursing job. They dont give a damn about you at all. It's all about the fucking money. read more

They make their money from theft and lies. Not only does their poorly unAmerican device pick up everything besides alcohol and say it's alcohol. Once you take it in, it shows it's a false positive, and with the device in recall; they will report it to the dmv as violation just so they can continue to charge you. Their device constantly messes up so you have to continuously take it in, so they can charge you more and you have to pay the mechanic too. Every time you call in, each and every different employee finds a new and different lie to say which is astounding. They will do everything to bleed you dry. If you want to be able to pay your bills, get stuff for your only child, pay for anything medical expenses Do Not Go with them. They're the embodiment of corporate greed read more

Fair warning to anyone who reads these reviews. I wish I had. If I put my conspiracy theory's aside, we can just call it terrible equipment. Either way it costs much more as lockouts are frequent. The codes (explanation for issue) are arbitrary and make no sense. Either way these issues yield the company and their service providers much additional income. Let's not forget the phone tree and hold times! I finally gave in and insisted that I get a removal order. Mind you they want to complicate this and charge you more money. With my removal finally scheduled, the next trip allowed my sample then rejected every followup attempt putting me in a lockout. One more wad of cash out of my wallet. With A different service provider I find this requirement much less painfull and less costly. read more

Comically bad customer service. I spoke to (not an exaggeration; I counted) TWENTY SEVEN people to get a disputed charge removed from my account, only to have someone call me the next day to let me know I was charged anyway and they could transfer me to customer service to get it taken care of. THEY CALLED ME TO REPORT A MISTAKE THEY HAD MADE AND WERE ASKING ME TO WAIT ON HOLD TO FIX IT. As I'm writing this the issue is STILL not resolved. Intoxalock is a worse company than AT&T. read more

Do your homework before signing up with this company...it will save you a ton of headaches and $$$! Terrible customer service and bogus charges to boot. They gave me a goodwill credit which they promptly reversed first chance given. This company acts so shady it's unbelievable! read more

This company is horrible!! They make so many random mistakes, and they're handling people driving capabilities. It's unbelievable how horrendous their customer service is. I've tried calling them for 2 days because I went to have calibration done yesterday, 8/25/2025; I received my receipt from Tint World (where I take my car). An hour later I get my email confirmation from Intoxalock, and whoever typed in my information they received from Tint World, actually typed in the incorrect date!!! They put the date down as 8/15/2025, instead of 8/25/2025! How are these people in business making numerical errors and they're in charge of my livelihood with the state of Florida!! It's completely unacceptable, and a horrible situation to be relying on totally incompetent people! I've tried calling them 6x and can't get a live rep, I've emailed them twice requesting they correct my receipt and put in the correct address, and I've gotten no response! Big surprise, all they about is getting paid; they offer no customer service, and complete incompetency! Disgraceful read more

Stay away !!!!!!! This machine is unsafe ! It turns off your car And their customer service is horrible ! My dad is a mechanic and does maintenance on my car always !!! I've never had issues with it Then when I got this Machine it kept turning off they insist it was my car battery And my fault for not maintaining it. Well I got tired of having to charge my battery and bought a brand new one ! Spent over $200 dollars. And once again my car is turning off ! I am thankful that it hasn't turned off while I have my baby in my car and thankful I have not gotten in an accident! Horrible horrible horrible company! Stay way from them read more

do not use this company! they do nothing but lie to you from day 1 and make it impossible to get out of your contract!

Worst company and device. They lockout the device often saying I tried to start my truck without giving a sample. They charge more than what they tell you and they threaten not answering questions without paying them. I could go on and and I'm so livid right now. I'm in AZ and have had this company over 6 months I don't not recommend Intoxalock of you got a dui and need an interlock device. read more

If I could give them a zero I would, their device saps your battery and ruins your electrical system and their service is HORRIBLE you can be on hold for an hour and still no answer and we had the device removed at a place they recommended and they still took money out of our account. Their is no option in their phone queue to cancel, if you give them your credit card they will continue to take money even if you no longer have the device. Worst experience I have ever had with any company. read more

Customer service representatives are brainless, not to mention there's clearly a language barrier because intoxalock is cheap and hires overseas. They will charge you for anything and everything, robbing you absolutely blind. They love to make a pretty penny just to mess you. This company is the worst. read more

So bad, just bad service all around. The hoople heads have done nothing correctly. Nothing. And the device it terrible, the instructions are bad. 3 hours at the dmv to find out they didn't complete the paperwork correctly A manager called me after I left a 1 star review on Google (that's what it took to talk to someone) and told me corrected paperwork would arrive Monday. It's now Thursday . Intoxalock, they put the S in suck Don't use this company, please, and if you have their stock, sell it. Amazing, they are still in business, but hey, Bernie Madoff ran a great bank for a while right? read more

Very bad service never trust this company never they charged 29.99 which I canceled right away for their services because of their reviews they would not give my money back very poor service. I would never recommend anybody to this company at all and the staff big liars. read more

I realize having an imterlock is an inconvenience but this seems like an outright scam. I don't complain or take review often but anything has to be better than this company. They will not remove my device and I've finished weeks ago. read more

Everyone makes mistakes in life. Please don't make the mistake of using this company. Multiple things were installed incorrectly and there is zero customer service. I spent a lot of my time running around trying to fix their mistakes. read more

My car is currently in a lockout again. It seems to happen about every month or two automatically when you plug it back in after taking it out the car for cold weather. Read saying it has a violation 12 . Even though I unplug it and plug it in the same way all of the time. I first put it on power saving mode and then unplug it after it dies down. However, sometimes when you plug it back in it says lock out violation code 12 and they charge you $75 or you cannot drive your vehicle. I've paid them over $1,000 from this type of thing happening over time. Just in fees. I have to call them now for the same issue. I'm fed up with this. There is a class action lawsuit on facebook. Hopefully we can get some things changed. Because this is very unfair to the public. And we cannot do anything about it. read more

The installation process was great, awesome customer service but after all that was done, it was almost impossible to work with these people. I had to send an EMAIL request to get my device removed. I sent in the required documents and I didn't get a reply until the moment after my account had to be charged for the following month. Since removal, I've been charged for roadside assistance every two weeks! I have ADHD so there's almost no keeping up with that. I tried calling about it and they said I needed to send an EMAIL to cancel the service that I assumed came with the device? This was no fault of my own. Technically I had no "active account" so how was I to cancel something I don't have? I've been getting these charges since March 2023 and now all of a sudden they have online chat where they can take care of you. The moral of the story is I've been scammed for months and I'm still unsure if they are going to refund me. I have yet to receive a confirmation email of cancellation but I did get another email saying they were trying to charge me again the moment I was done with the "chat" so there's that. Be careful, ask all the questions, try to be as thorough as possible and don't drink and drive. read more

They do NOT even deserve 1 star: DO NOT USE INTOXALOCK....DO YOUR HOMEWORK BEFORE USING THIS COMPANY. This is a review of the experience that we have had with Intoxalock. This is the worst company and product that I have ever seen. I want to warn anyone who is considering this company to rethink your choices. There are many other products out there...DO NOT USE INTOXALOCK. We put this on my son's vehicle almost a year ago. Not only is it super expensive, it is damaging to your vehicle. During the 11 months that we had it, we had to have the vehicle towed at our expense to a service location because the unit would not work. The service location had it for 3 days waiting for Intoxalock to send them parts. We were 3 days without a vehicle. Then a couple months later we started having trouble starting the vehicle. After many days of having to jump start it, we took it in and put a new battery in it. Not even 3 weeks later the vehicle was dead and needed to be jumped every time. I called intoxalock and they were not only rude but very unhelpful. Each time we called we had to wait on hold for 30 to 45 minutes. Horrible customer service. The worst I have seen in a long time. We decided to take the Intoxalock off and put another unit on. I called Intoxalock on 3 different occasions and told them the only reason we were taking this off was because it was damaging our vehicle and we were not able to drive it without jump starting every day. They did not care or offer any suggestions for the issues we were having. They charged $228 in administrative fees to remove it. Not only that the service location charged $110 to actually take it off, and the new company charged $207 to put a different unit on. If you don't want to completely waste a bunch of money and cause yourself a TON of aggravation and stress, DO NOT USE INTOXALOCK. read more

This company is a borderline scam. There are other options, so choose some thing else. We had a unit voluntarily installed on a vehicle, and we had nothing but problems, extremely poor customer, service, and a complete lack of caring, even though I was an optional customer. The experience was so bad that we remove the device from the vehicle. Beware of the hidden charges and fees and fines they will assess. The cost will go up. The system is difficult to use, there is a series of inhaling and exhaling with specific trimming that must be accomplished in exactly or else you have to re-try and after a couple tries you automatically get fined. Once again, we had this installed optionally and voluntarily and I feel extremely sorry for anyone who is forced to have this device because the company takes advantage of this leverage. read more

If I could give them a negative star I would. I've been with this company for 1 1/2 years and it's been nothing but positive since day one. I have had to take my car in 5 times for faulty equipment. Miss work and valuable time to do this. They have hidden charges they add on all the time not telling you before hand about them. Customer service is horrible you're lucky to get a person you can understand. I could keep going but I'm already starting to get upset just thinking about all this stuff. Go with a different company believe me. Consumers beware..... read more

If you want to go with the worst company on the market these are your guys. First expect to pay lockout fees even after declaring that maintenance will be done. Second expect very long call times no one ever picks up the phone and when they do they are totally lost. I've been dealing with this company for a year and it's literally the worst. They will charge you for every thing even if it's something out of your control. Did I mention how bad the customer service is 1/10 read more

terrible customer service. I've been trying to get ahold of someone all day and can't get ahold of anyone to address the problems with my account. read more

Liars and swindlers. Hidden fees. Try to force new lease. Customer service trained to hoodwink you.

I've had this device for about 18 months, this has been a true nightmare. Every time you need to get a hold of a representative, make sure you designate at least 2-3 hours. Then once I finally get a hold of someone, my issue never gets resolved. Please do yourself a favor and go with a different company. They've made it impossible for me to get this device removed and I'm about to get a lawyer to help me resolve this, I was able to get my device removed (according to the state) over 6 months ago....this is how difficult it is to get even the simplest things done with this company. 0/10. read more

worst company ever!!!! costumer service sucks. i get violations for no reason. no resoluton. They will just say pay and it will go away! Worst worst. Better off doing jail time for the dui.. read more

Have had device for 6 weeks. Have not had problem with it BUT I have not gotten my $100 install refund and CANNOT get to talk to anyone about this. Their customer service number is completely automated and there is NO option ti talk to a person. Absolutely ZERO oppportunity to select an option tp SPEAK with ANYONE. Bullshit customer service. PICK UP THE PHONE ASSHOLES. They take their money everytime its due but i cant talk to them when i need to. THEY SUCK. They only get one star because thats the lowest rating allowed. They truly deserve a ZERO rating read more

God I wish I had read the reviews before I Volunteered to have this device installed. ALL the problems mentioned.1. multiple lockouts for no reason.2.no connection to starter when I've blown clear multiple times 3. impossible customer service, nice but borderline ineffectual when you have to lie to get a human. 3. got run wire warnings and other sporadic notices. 4. Yes Brandon was very helpful with all my initial issues but mailbox is always full and no longer responds to text. They do issue credits but good luck, I just found out I have a credit for last (not latest) faulty lockout but was never told. I think many employees are doing their best but its obvious the company itself is just set up to collect money and keep you from actual customer service representatives ( unless you want to open an account!) read more

They're HORRIBLE, I mean HORRIBLE, I cannot even begin to.type.all.of the negative things,.it would take too long. They're also extremely rude.and poor customer service! RUN, DON'T WALK, DO NOT GET THIS COMPANY read more

Horrible customer services. I was quoted 10.00 less per payment, 20 per month and 240.00 more annually. Multiple lockouts due to maybe a low battery that the service center says drops to 8v and orielys and I myself can't get less than 11v on crank. Don't attempt to get any technical service from this company.. unplug and plug it back in type of fixing their issues. I asked minimum voltage required to tech support who said on repeat 12v and had no clue it drops when you start your car. 110.00 each lockout.. causes unknown nor proven yet you must pay within 2 days to keep using your car. An absolute nightmare to deal with and I wouldn't recommend them to anyone.. even if I didn't like them. I will be adding this to all review possibilities. Please do not make the same mistake I did. read more

Well here is my latest experience with Intoxalock. I have been trying to talk with someone who can answer my questions about my upcoming service appointment at the dealership. I want to know what to tell the mechanic. How does it work? I have reported the service on the website. No luck talking with a person or even the chatbot on their website which keeps me going round and round through the same thing with no answers. I'm afraid to take my truck in on the chance of a lockout and not being able to get it removed as there is no one there. read more

ZERO STARS!!! They called me to tell me my device was not working correctly. I asked what our options were and they said to bring into get serviced. I did - no issues a month later got a letter from the state stating I was not producing readings. Called Customer Service and they told me to bring in to service it. I stated ok we can do that but we just did and that did not solve the problem so can we work through this together. they got rude told me the same thing over when asked to speak to someone else was refused and HU on. called back and was on hold through multiple channels for over an hour when I got a "manager that was so rude to me, talked over me did not help and just started repeating everything I said to him back to me. Still have not heard any reason as to why the device is not working correctly and they state I have to pay for the charges to fix it. Maybe one or two reliable people to talk to otherwise they are all rude, do not listen and treat you like dirt. FIND ANOTHER COMPANY!!! read more

Worst service, Worst equipment and WORST CUSTOMER SERVICE IN THE HISTORY OF HUMANITY! Yes I made a mistake and paying for it but it doesn't give Intoxalock the right to treat you like crap, faulty equipment had me in lockout twice and violation with DMV. Replaced battery and thought it was the vehicle so I sold it and bought newer one, same damn crap it even drained battery on new installed vehicle. They told me if it's equipment failure they will refund lockout charges, after device swapped out they said it was due to vehicle issues even after technician said it was device. Nothing but a scam! STAY CLEAR UNLESS YOU WANT THESE NON ENGLISH SPEAKING OVER YOU! read more

Customer service is a joke! They make it impossible to get the device removed. They have all kinds of hidden fees and extremely small writing. they sucker you into doing longer than the court orders because of their bs lease agreements. I had to do almost 3 years for a 2 year court order!! These guys are crooks dont give them your money, you'll be stuck with them forever!! And their expensive!! Screw intoxalock and they try to get you got missed blows, it's like $90 to get them to reset!! bs!! waits for you to get out then it goes off every time!! read more

BEFORE READING THIS JUST GO AHEAD AND TAKE INTOXALOCK OFF YOUR LIST OF POSSIBLE PROVIDERS, HERE IS WHY. If you're court-ordered to use an ignition interlock device (IID), avoid Intoxalock at all costs. My experience with them was a frustrating nightmare, riddled with poor customer service, unreliable equipment, and deceptive sales tactics. False Promises and Rude Staff: From the very beginning, the sales pitch didn't match reality. Intoxalock promised a smooth and hassle-free process, but their customer service was far from it. When I encountered issues, I was met with rude and unhelpful personnel who seemed more concerned with quotas than resolving my problems. His name is Michael Predmore, and he was completely inept, greedy, and a transparent dollar-is-king kinda individual. He sent me the wrong equipment required for my location, and after the initial installation when I CAUGHT the problem, not him, I had to sacrifice my time to have the device removed and the correct install completed at their expense but at the cost of my time. He was very responsive during this process, I would guess until he knew he would get his commission, but once that was assured, he immediately stopped with that communication nonsense and in a final email made sure I knew he couldn't help anymore, and for me to contact customer support (outsourced to South East Asia of course). PRO-TIP: If you already have their service, then you can bypass the outsourced customer service and circuitous routing process, by calling from a number not in their system. This routes you DIRECTLY to sales, new money get the best effort! They will then route you to customer service, in the hopes, that if a sale comes out of it, they will get credit. After I did get the correct device, they created a whole new account for their app (which sucks), and it took a month to get my payments on the initial account transferred. They also tried to bill me for a lockout because I disconnected the handset to prevent exposure to cold weather as I was instructed to do by the service center, that's that sleeve you get that can only be removed or installed by disconnecting the device, and makes the already bulky handset impossible to hide. The handset is bright white, and extremely obvious, to further the humiliation you probably already feel. But don't lose the sleeve the koozie-like material sleeve must be lined in platinum because if you lose it you will have to pay a fee for that too. Substandard Equipment: The interlock device itself was unreliable and prone to malfunctions. False positives and technical glitches caused unnecessary stress and delays. About six weeks after my installation, I was contacted by Intoxalock because they were having communication issues with the device. They needed me to bring in the device (and my vehicle) for a tampering inspection, to verify I hadn't messed with the equipment (I hadn't and I told them that, but I'm a horrible person who got a DUI, so I am also a deceptive liar who couldn't be trusted) my work schedule is done two weeks out, and I couldn't surrender my vehicle for several days for their verification. I did schedule an appointment a couple of weeks out, but by then my monthly calibration was due, and they wouldn't calibrate it until the inspection was done. Because even though they were having the same problems with other customers, they assumed it was a tampering issue first, before even considering the historically faulty equipment. PRO-TIP: Do not blame your service center if you already have this equipment, it's not their fault. My service center, which I won't mention here as not harm their business by linking them to this horrible operation. They are the ones who arranged for a tow and the information about the other equipment issues. So I lost the vehicle for 5 days while the inspection was done and new equipment was sent and installed because I didn't tamper with it, as I told them, and since they wouldn't spend the money on a new device and shipping until they had proof it wasn't my fault. My service center arranged for the tow and billed them directly. If they hadn't I am sure I would have been out of pocket for that as well as the time off work. They refused any kind of billing credit for my inconvenience, after all, it was my fault for being such a reprobate and getting a DUI, so I deserve what I get. Deceptive Practices and Hidden Costs: Intoxalock downplays the ongoing costs associated with their service. Be prepared for surprise fees that weren't mentioned upfront. i.e. Roadside assistance I didn't need, a sleeve for the device, a separate lease fee for the wiring and camera, etc. The whole experience felt like a money grab rather than a genuine effort to help people regain driving privileges. Overall, a Negative Experience: Intoxalock turned a challenging situation into a frustrating ordeal. Their unreliable equipment, coupled with their poor customer service, made the process significantly more di read more

Instillation was easy. Intoxalock is not helpful or no it does their customer service have any knowledge base around your case even after reading case notes. They are unable to tell you anything including final calibrations if needed or reporting details. They continue to unnecessarily charge customers fees, no violations or missed calibrations the lease expired over 30 days ago and we are still being charged because they will not do what is needed so the device can be removed. They are extremely negligent to their customers . This is a sorry, company and I would not recommend them to an anyone for any reason ever my advice steer clear. If you were needing an interlock service, do not use Intoxalock . read more

In PA you need to have no violations for the 30 days before your time is up. I've heard of many people's devices giving them baseless violations in those last 30 days and keeping them on the hook for much longer than their allotted time. Use literally anyone else. This company is a sham. You can follow this process to a T and still come out with MANY violations based on the way you start your car and turn it off... nevermind any drinking. You will NOT be able to argue these violations and they will be reported to the state. Good luck on getting ahold of someone domestic involved with the company and if you do they will try to shame you for having the device at all. I wish i read these reviews when i thought they were all bad. DO NOT THINK THIS WON'T HAPPEN TO YOU. read more

I wish I could give them -5 stars. Intoxalock is by far the worst interlock company, I strongly encourage you to use literally anyone else. The costumer service is subpar, the devices themselves are so outdated that if you have a car 2010 or newer you will have nothing but problems and intoxalock does not take accountability for that. They will tell you it is your car and you will replace everything possible until they will finally admit it's the device and then send you another that also doesn't work. Save yourself the headache, thousands in unnecessary repairs and thousands on other forms of transportation while you wait on them and go anywhere else. read more

Absolutely the worst customer service I have ever experienced. Was told when I moved that there would be no problem. I have been trying to get my intoxalock calibrated and they have basically told me tough. Take the car back to California. I am now stuck in Texas with 1 day left for calibration and the people at intoxalock have been the rudest, condescending, unwilling to help people I have ever met. I did my part and reached out before I moved and was told no problem happens all the time. Now I am being punished for intoxalock employee incompetence. I will never recommend this company and will look to file a lawsuit for lost wages from getting to work and anything else I am charged for this nightmare read more

DO NOT USE INTOXALOCK!! Look for a different company to get an IID. I was referred to this company by my attorney's office and I regret it. When you first call, they seem nice, helpful, and responsive. Once you get the device installed in your call, good luck getting a hold of a person, especially without 30 minute wait times. The machine itself is ABSOLUTE TRASH. It's dated and extremely sensitive. It requires you to exhale-inhale-exhale. Even if you're following their 3-2-3 count, it'll randomly start beeping. After only 2 weeks of the device being in my car, my car battery died!! I had just gotten it replaced the month prior. When I called AAA to jump my car, the device wouldn't allow it. I would breathe into it and once cleared, I'd try to start the car. NOPE. The device would make me wait 2.5 minutes before trying again. Eventually, I decided to get the damn thing removed from my car. I called the DMV to see what consequences I'd face and it turns out they advised AGAINST the installation of the IID when Intoxalock's representative called the DMV to let them know of installation. All of that, and I still had to pay remove the device. This company is a scam. Bunch of crooks. Save your money and find a different company. read more
