    The guys at the shop are awesome! It is the Intoxalock customer service representatives on the phone that are terrible. I have been trying for two months to get it looked at and have been getting the run around. I call and the CSR says the can not reach the service center, that no one picks up the phone and I would have to call back. I hang up call the service center they answer and say they are here and have not gotten any calls. This happened three times.

    Customer service does not give you ALL the information you need. I had to call more than a few times in one day. I was put in the wrong county by them and I had to provide proof of what county I was supposed to be in.

    Customer service DOES NOT give you all the information you need. So always have a list of questions in front of you so you don’t forget to ask anything. When I say customer service I don’t mean the service center that installed I mean Intoxilock’s service representatives they will only give you information you are asking for no more no less. Then I had an issue with the county I was put in. Francis Hensley put me in the wrong county then I had to prove what county I was supposed to be in.

Frequently Asked Questions About Intoxalock Ignition Interlock

How does an interlock device work?

Once the device is installed, drivers blow into the car breathalyzer mouthpiece to provide a breath sample. The device tests for breath alcohol content (BrAC) within the legal limit. If it's under the limit (typically .02), then the driver can put their keys in the ignition and start the car.

What is the cost of ignition interlock device?

An ignition interlock device, also frequently referred to as a car breathalyzer, ranges in cost between $70 and $150 for installation. This fee is a one-time fee paid at the start of your lease period for the device to be installed into your vehicle. This fee is paid directly to the service center for the work done to complete your installation.
