    (Update at the bottom) Everything with the device has been fine until today. I checked my account and I have a balance. I was initially told by Reyna that installation and shipping and everything else would be free. After the initial install, 2 weeks after, I would be charged. And now the device says my battery is low? That battery is not even 2 months old. I understand that the battery needs to provide for both the vehicle and device but I find it ridiculous that it’s draining my battery THAT MUCH. Considering that I had to bring my device inside due to the weather and I haven’t even driven my vehicle since Friday. Update: Patricia reached out to me and better explained the situation for me! We were able to resolve the issue with the balance on the account and get everything squared away! And with the battery, i guess it might have just been that I hadn’t driven the vehicle, everything seems to be fine with it

    You can't get a hold of anyone and they are not helpful if you finally do get someone. The technician got his dirty hand prints all over in my car and it looked terrible when he was done. Extremely rude and barely speak English.

    The guy was poor with his explaining and did nothing to show me how to use this device. He told me to download a QR code and when I did it was in Spanish. I do not speak Spanish. Then he tells me to read the packet. After I left I got a few blocks away and the machine starts beeping and I had no idea why. So I went back and told him and he blew into it and got it going

    I was told my services to install would be waived due to a "promotion" and then after I set up my account on the app the day of installment I have a overdue balance of 151.43 to pay when I just got on and was told to only pay $51 dollars and change every two weeks. If I've known they do me dirty like this i would have went another direction for sure. Only had this thing for two weeks..... how!? Make it make sense. (This was a 1 star when I first made this) However the same day few hours later, Patricia called me about my situation and resolved everything and made things put at ease on my part eventhough I was ready to blow off steam on someone she listened to everything I had to say and really understood my frustration and made me feel alot better after I was heated at the beginning. You get her make sure she's on speed dial in your phone. She's great. Thank you for resolving everything and making things easier and better on my end. (It would be 5 stars but the fact I had to even deal with this situation in the first place is deducting a star and why im doing 4 instead of 5.)

Frequently Asked Questions About Intoxalock Ignition Interlock

How does an interlock device work?

An ignition interlock device (IID) is a small breathalyzer installed in your vehicle to prevent it from starting if alcohol is detected on your breath. Before driving, you'll blow into the device. If your breath alcohol concentration (BrAC) is below the programmed limit, the car starts. Periodic retests occur during your trip to ensure continued compliance. To read more on Intoxalock, you can read our ignition interlock device guide.

What is the cost of an ignition interlock device?

The installation of an ignition interlock device, often called a car breathalyzer, typically costs between $70 and $150. This one-time fee is paid at the start of your lease and covers the service center's labor to install the device in your vehicle. Payment is made directly to the service center at the time of installation. For more on cost breakdowns, you can read our cost of ignition interlock device guide.
