Their customer service system is terrible. I was on hold for one hour on two separate occasions yesterday and both times it rolled to a voicemail and I still have not received a return call back. The system says push 8 to leave a call back number and save your place in line and the 8 option does not work. I would not recommend this company to anyone.

If you want a real review from a real person that you can actually contact read this!!
The overall company as far as customer service white times quality of the actual unit that is put into your vehicle. I gave one store, the unit seems to be made roughly in the late 80s early 90s. Do unit electronically malfunctions with a regular basis as of 26 months in the program I currently have 90 $50 fines and that doesn’t count my monthly payments. That is with NO alcohol violations!!! To date I have two $450 nonrefundable hearings I have paid for I went to and have not lost my license yet but I’m sure on my upcoming third $450 nonrefundable hearing they probably will and the crazy thing is I almost made it to my three year mark. Looks like I’ll be starting all over again and never violated for alcohol. So with that being said we would like to welcome you to the Monitech family were your business and your safety is our number one concern.(key toilets flushing sound)

Customer service
The guy at the Asheboro office is one of the most UNFRIENDLY people I have met. We all don't like the fact that we have the THING in our vehicle, but when we go to pay and get our device checked on. At least the person doing your device can have some personality. Didn't ask if the next date to come back was a good date and or time for me, just highlighted the date and time handed me my paperwork. Fortunately the date and time he just GAVE me works for me. But if it hadn't he would have had to print out another one.
The guy at the Greensboro location was great, smiled, joked was happy that I was early, his last for the day. Meaning he could go home a bit early.
Asheboro guy????
Never smiles, doesn't engage in any conversation. Doesn't say hello or anything like he doesn't like his job. Walking robot.
Get a grip dude 🙄

After in Monitech (Ignition interlock) fried my vehicle.stallation of interlock by…
After installation of interlock by Monitech, my alt went bad (or so I thought) had it replaced. Gremlin's in dashboard telling me charging issues flashing, staying on etc. Went bad again and took out battery this time. Had both replaced again. Battery was new. Wiring checked. Battery died, replaced again, wiring checked again. 3x because of flashing lights on dash. Mechanic said only thing it could be was interlock and they were not authorized to touch it.
Noticed that when I would grab the interlock to start car I was getting popping noise from under the dash. Car is not on. Only thing touched was the device. Called Monitech, they said not them. Asked installer to check work in november. He did not do it. Asked again in December. He went outside to car for 5 minutes. Came back in and grabbed his tools and was out there for 25 minutes this time. Came back in and said all tight. And guess what, it was. So $7000 in Tows, parts, labor and ubers, car seemed to be fine.
Waited a few weeks to make sure. No issues. So file a case with Monitech for the repairs and towing as it was obvious it was installer fault as it was fixed when he finally went over his own work… 4 months later. They did nothing. Not even a call.
Sensor went out 1.5 months later. Car was taken to transmission shop first, they said transmission was fine. They started and drove the car and it was throwing a few codes. But they did not do that kind of work.
I called an auto repair shop around the corner from them. Mechanic drove car to his shop. Informed mechanic what happened with device prior. He called me the next day and said I was looking at chasing electrical issues since my car had the short in it so long. Other components would start to go that were electrical because of what electrical short do to connected electrical. He stated the car was not worth fixing.
Filed another claim for loss of car. Received a call from mechanic saying Monitech was there adn they were going to tow the car. I was told nothing by Monitech. I said do not let them tow the car. 1.5 hours later Carl from Monitech calls me. He and his technicians were there and could not find fault in the wiring from their device. I explain the story to him as I did above and said that was fixed by the installer finally in December but the damage had been done. He said I should replace my battery. I said he may want to look at the battery as it had been replaced 2x already in last few months and was only 2 months old. He said he understood what I was saying and would call me back. Never heard from him again.
His supervisor called me. Would not allow me to talk. Just kept trying to explain electricity to me. Something about a person sticking a fork in a light socket and dying. I was like what? After listening to him for 5 minutes, I asked him if he read any of the emails I had been sending regarding the electrical issues and what had been happening. I said Carl seemed to understand. He seemed mad and said I will talk to Carl and get back with you and hung up. Never heard from him again.
The following monday I went to the shop to get my belongings out of my vehicle. Vehicle hatch would not unlock. I thought odd. Opened drivers door and the Interlock device was gone. Tried to start car and it was completely dead. Not even a light would come on. The mechanic came out with booster/diagnostic box. We started the car. He said the Alternator is shot as well. Both were only a few months old and remember the car was driven by 2 mechanics before Monitech got there. No one told me they were taking my device. No one called me. Nothing.
Knowing not having device in my car would cause me to lose my license I immediately called Monitech. They had no record the device was removed. I received a call from another supervisor the next day. I told them my story and that because they again messed with my car by uninstalling the device my alternator and battery were yet again shot. He said "prove it". I was like It drove there with no issues. I had no issues since the installer fixed his work in December. It was now late February. There were no battery or Alternator issues until they touched my car and took that thing out. He said was on me to prove it.
Needless to say not too long after I received a notice from DMV that my license is revoked because I do not have interlock installed. I called the DMV Interlock division and they said there is nothing they can do. That I surrendered the device. They said per Monitech it was voluntarily removed. I told him it was not and that I had also contacted my DMV hearing officer prior to that and she said whatever I do, do NOT let them take out the device. Why would I let them remove the device as I knew what would happen.
So now I am out $7000 in repairs, $9000 vehicle, and my license.

Vehicle battery problems are not usually related to the interlock device, although the timing of a battery problem can make it seem that way. We have had multiple Monitech technicians and managers review your situation and found no device/wiring fault. Outside mechanic shops have also been able to determine that the issues were caused by the interlock device or wiring.

This company does NOT care about it's…
This company does NOT care about it's customers my truck has been in permanent lock out for over 24hrs have called the number numerous times trying to pay $45 to get the code needed so I can start my vehicle it's currently Sunday the offices are closed so you depend on someone answering the phone to the 24hr line and you never get though to anyone it rings until finally your sent to a voicemail when you leave a message your never called back theirs been several times I've left messages and never get a call. Your truly at the mercy of these people that don't care. This is the first review I've ever left on any place of business but if this can just help one person not end up in the position I'm currently in it's worth it. Wouldn't be near as mad if this wasn't a constant problem it happens every time EVERYTIME I've ever called needing help..

If I could give 0 stars I would
If I could give 0 stars I would. The equipment constantly gives false reads in which you have to pay $45 every time to clear. Like how did I fail and seconds later pass but still the $45 is required. Then here I am now needing to go in for the 2 month check and the agent scheduled me for a location that was closed so of course I had to pay $45 again even tho I showed up with no one there. Spoke to another agent same day to avoid my car getting locked again as I do have a job scheduled another appt and of course the car was locked!!! This is completely unacceptable and truly unconstitutional. I will be removing it and going with another company at my next appointment for sure. I have had 2 out of 10 decent experiences with agents all others were remedial.

We appreciate your feedback and understand your concerns. All Ignition Interlock Device (IID) settings are dictated by state regulations. Please note that the IID will register any trace of alcohol from any source containing it - this is how the device effectively ensures an impaired individual cannot start a vehicle, and how we can confidently state the Monitech ignition interlock is fulfilling its purpose.
