Great service, install only took 45 minutes, you can pay ahead or autobill and set your appointments out up to 90 days that way you don’t have to bother coming in every month. Also if its a second or third d.u.I and depending on amount of time you are required to have the interlock in you can get lower rates.

A1 interlock is a great place to go if you need to get an interlock. They were extremely fast when I needed my interlock installed same day so I could go to work. Quick and easy monthly calibrations. Friendly staff. I would recommend this business.

Still this company surpassed all expectations! When I was dealing with insurance companies to install a second interlock in a rental; Zack went above and beyond to get everything I needed done in a quick and professional manner. Thank you Zack!!

People are nice and friendly. The only reason I’m giving 4 instead of 5 is because of the interlock itself. It is not 100% reliable or Accurate. Have had issues with it due to it being so hot outside.

There’s a reason this place has a million more reviews compared to any other interlock business. The people are reason enough to go there (Zack) but the device is easy to use and the pricing is fair! Don’t be stupid and give anyone else your business!!!!

They are really friendly, are more willing to work with their clients. They aren’t out there to charge you for everything. They did a free install. They explained exactly everything and there entire process. This is the second company that ive tried, and this place is 200x better than affordable interlock, and the prices are better.

I’ve had an awesome relationship with the guys here. Finally getting my device uninstalled but these guys are very understanding and true about there work it’s amazing. I would recommend a1 interlock to anyone needing an interlock device. The devices are very dumb proof. Very fast and awesome. Keep it 100!

I’m getting older and got my first DUI late in life. The judge ordered me to get an interlock device for my station wagon. I looked online and saw the great reviews on A1 Interlock, and they were close to my house. I talked to Aaron Michaelis got all of my questions answered. And installed a short time later. Ill be glad to get this taken care of with the courts, but A1 made it alot easier. Thanks.

I was incredibly stressed when I had to get an interlock installed in my car because I didn’t know how long it take to get in, or how it works and all that. I called and Zack was the who answered my questions, him and Aaron are awesome!! Got me in right away and the installation was done faster then the other places that I had called! A bonus to me was that the interlock is made local!

As unfortunate as it is to have an ignition interlock, A1 interlock made the entire process much easier than i thought it will be , the device is simple and so easy to use great bunch of people work there, i called the other interlock companies in town A1interlock prices by far the least expansive device and so easy to use , they are amazing i had my interlock in my car for 3 months now and i wanted to wait to see how the service will be and like i said hands down amazing customer service these guys are actually help you through the process and service of your interlock just want to thank sam and Aaron for great service you guys have thought me not to drink and drive ever ever again.

Getting an interlock in my car was not something I was excited about after my Dui arrest. But after I called A1 Interlock and met their knowledgeable staff I was relieved. Their prices were the best I could find anywhere in Salt Lake. I would deffinately recommend them to anyone going through this kind of experience. They made it great. Thanks A1 Interlock

A1 Interlock is probably the best place to go after getting a dui. John was really helpful and polite through the whole process. Would definitely recommend to my friends.

My wife was so mad at me when I got bailed out of jail for my Dui. And then add insult to injury then having to get an interlock device for our family car was scary I though. When I first met John Mccomie at A1 Interlock I immediately felt better he answered all my questions and gave me a better price than anyone else I called. He has been a good friend to me each time I’ve come in. Thank you A1 Interlock. I got my life back.
