Gary is great. I've dealt with my fair share of locksmiths over the years having management multiple rental properties. In this instance I needed deadbolts swapped out and upgraded from the old school manual to newer digital version. The newer version had a larger deadbolt Than the one currently installed on my doors, this the hole had to be re-drilled larger. I was not comfortable doing that. Gary had straight forward pricing and was very easy to schedule. Other places tend to have hidden fees and end up charging you more than originally quoted- so their prices seem cheaper upfront to get your business but ends up being more expensive. After Gary updated two deadbolts to the digital versions the price came out exactly as quoted. He also rekeyed everything on the same key in the event the key is ever needed. The price came out exactly as quoted. Beyond price he is just a super nice guy and clearly an expert in his field. Highly recommend Gary for any of your lock or security needs. read more

Locked my keys inside the car, late evening on a Sunday. Found this business on yelp and they were the first to answer! Quick phone call, shared the details of my issue and made the appointment - someone arrived within 30 minutes of my call.

I returned to Mount Prospect from an out of state visit only to find out that the inner workings of my deadbolt were broken and I was locked out of my house! Gary came out the same day, in the pouring rain, to take care of my problem. He changed the lock and then rekeyed all of my locks so I didn't have different keys. To top it off - he and then made me extra keys!! He was a life saver! After having to drill the door resulting in shavings, he cleaned up the entry so that it was spotless! Gary is friendly, professional and skillful. I highly recommend him!! read more

Great job Gary - thanks for your help - you were prompt and professional - will call you next time too!

My husband found Gary on Yelp and made the appointment to get our locks rekeyed, as well as help take out a key he had broken off in our Yakima cargo box. Gary was methodical, patient, and answered all my questions. Our locks work great! He also didn't give up on working out that broken piece of key in the cargo box lock, even though it had corroded in the lock over the past three years... Thank you Gary! I highly recommend Gary at Expert Lock & Security and would go to him again for any of our lock & key issues. read more

His prices are reasonable, fair, and consistent, and I will be using him for all my future locksmith needs. If you need a locksmith, Gary is your guy! read more

Gary from Expert Lock was an incredible help in our move. We wanted a smart lock for our front door and he gave us wonderful advice beforehand on what to buy and to make sure we didn't buy too early in case we needed to return something. We talked on the phone to confirm the date and time, then he called the day before to confirm. When the day came, he did great work and continued to give great advice when rekeying and installing new locks! Very happy with his service! read more

I moved into a new house and needed to replaced 4 door locks and dead-bolts. Gary answered the phone immediately, scheduled the service quickly, arrived on time, did the work in the amount of time he estimated (1 hour for 4 locks and deadbolts), knew the manufacturer (I didn't), supplied extra keys, was efficient, and very cordial. I'd use him again. read more

If I could give 6 stars, I would! Gary is very responsive and professional. The job was done quickly and correctly! Very pleased!

I have called Gary twice in the past couple years. He always does a great job and doesn't over charge. I trust him. Recently, we needed the strike on our condo building's door replaced. I called several companies and all charged just for coming out to see what the issue was. Gary, (whilst he also charges just to come out for a job) had me send him pictures, so he already had an idea of the problem. I had confidence that he new what the problem was, came with the replacement part and finished the job efficiently. read more

Highly recommended. On time, efficient, helpful, reasonably priced. Gary does a great job. Thank you!

First impression: extremely easy to schedule. I called around 5pm on Tuesday to ask for a re-key appointment for Friday. Gary told me that I could do it Friday, Thursday, Wednesday, or even the same day. I had already planned for Friday but appreciated the flexibility. Second first impression: flexible AND understanding. I completely biffed the first appointment when my work schedule changed and I forgot to call and reschedule. I felt terrible, but Gary was very understanding and happy to reschedule anytime. When I called him again a few days later and named a specific date and time, he said "No problem, see you then." Final impression: the work itself was good and quite reasonably priced (there was also a Yelp discount). I did not attend the appointment, but my wife said that Gary was personable and quick. My cat came out to supervise the work and he was tickled (Gary, not the cat; who the hell knows what she thought). read more

Really knowledgeable guy! He also is honest about what you really need, no frivolous upsells. He was flexible with his schedule in an emergency, and we made a second appointment later for other fixes not related to the initial call. We liked his work so we definitely had no hesitation when we needed him again. read more

What a professional! Gary exceeded my expectations in helping with my recent move. I was able to book him in 24 hours through Yelp! He was 15 minutes early for our appointment and very quickly helped me through a garage door and 2 rekeys. Very friendly, informative and committed to customer service! Thank you Gary! read more

Perfect name for this business! Look up expert in the dictionary and you should find Gary's picture next to it! I've used Gary's services for several years for home & work needs and have never been disappointed! No other lock service compares to his professionalism, dependability, or price! If you have a need for any lock service, reach out to Gary at Expert Lock, you will absolutely be happy you did. read more

I'm always hesitant when people say there's a service charge to give you a estimate. They "can't give you even a rough estimate without coming out to see what needs to be done." No matter how much you tell them, or how many pictures you send, they won't even give you a ball park of how much it will cost. "I've had my fair share of paying service fees and then receiving a ridiculous quote for a job. Gary charges $65 service fee and gave me a rough estimate of $270 for everything I needed to have done. I felt that was more than fair so I made a appointment. After he finished a perfect job and cleaned up, He then tells me my total was only going to be $200?!? Also, since I'm a yelp customer i would receive a additional 10% off!! I highly highly recommend Expert Lock & security, not many honest hard working people out there but I assure you if you need a locksmith Gary won't let you down. read more

Gary was a true professional. He came when he said he was going to and went right to work. Very personal and knowledgeable. I would highly recommend Expert Lock & Security. read more

Gary to the rescue! After a failed attempt with another locksmith I sent a quote request via Yelp and Gary called me just a few minutes later. I locked my keys in my garage so that was problem number one. On top of that I had multiple doors where I was frustrated with the locks because they were hard to get the key in and turn and I had way too many keys for just three doors. I figured since I had to have a locksmith come open the garage that I'd just replace all the locks too so I could have just one key. I was ready for a major bill but when Gary arrived we talked about what I wanted and he ended up rekeying or resetting my existing locks and giving me multiple copies of a new key that works in all the locks AND turned smoothly and effortlessly in the locks. Did I mention he did all this in under an hour on a Tuesday night late evening? I am impressed, relieved, and very happy with the outcome for a very reasonable price. Excellent, honest, quality work from a super nice guy! I want to have an electronic keypad installed on my front door and I know just the guy for the job. Gary is now my go to locksmith and I'm happy to recommend him! read more

Gary is professional, prompt and hard working. Highly recommend.

I messaged Expert Lock & Security through Yelp and Gary, the owner, got back to me right away with a quote. He was able to come out a few days later to rekey (and consolidate) the locks in our house and fix a wobbly door knob. Gary was incredibly friendly, courteous, and professional, and his rate was more than reasonable. It's obvious that he takes pride in his work and truly values customer service. Definitely recommended. read more

We've used Gary 3 times now. He's a super nice guy. We have a historical home so getting things fixed can be challenging. But Gary took his time and worked his magic to make our 107 year old lock functional. The cost was very reasonable. But more importantly, we like knowing we have someone to trust to get the job done. read more

ONE OF THE FEW LOCKSMITHS WILLING TO WORK ON MOTORCYCLES ON LOCATION! I contacted 4 other locksmiths, and all of them said that they will not work on re-keying a motorcycle, much less meet me at the garage where my bike was being stored. A little background info, I have an older motorcycle that was purchased from a private buyer years ago. I recently moved and lost my motorcycle keys somewhere during the transition. I called a few dealerships, but none of them were able to help. So my only other option was to call a locksmith. I messaged Gary through yelp and he responded immediately. I told him my situation and he was able to quote me a VERY fair price. Right then and there I made an appointment. He showed up exactly ON TIME! Being late for appointments are a pet peeve of mine, so this was greatly appreciated! He was incredibly FRIENDLY AND PROFESSIONAL! For whatever reason, my elderly father decided to start up the lawnmower and proceed to mow the lawn, which was incredibly loud and distracting, while Gary was working on my bike. He didn't seem to mind the distraction, and even cracked a few jokes after I kept embarrassingly apologizing for my dad. He is VERY KNOWLEDGEABLE. He was able to take apart the gas cap lock on my bike and make new copies of my keys from that, all the while explaining each step of the process. After reassembling the gas cap lock, he would have me test each copied key in the ignition, as well as the seat and helmet locks (all use the same key) to verify that each of the copies work. I am definitely happy with his work and would HIGHLY RECOMMEND him! read more
