Calibration
Ignition interlock devices require regular calibrations that will vary depending on your state's regulations. State regulations require your device to be calibrated anywhere from every 30 to every 180 days. Ignition interlock device calibration ensures that your car breathalyzer accurately reads and records your BAC every time it is used.
Installation
Ignition interlock device installation typically takes around 1-2 hours depending on the make and model of your vehicle. You have the option to drop off your vehicle and pick up at a later time or wait in the provider waiting area while your car breathalyzer is installed.
Removal
Removal of your ignition interlock device is a quick and simple process. Your service provider will remove your car breathalyzer from your vehicle and return it to LifeSafer for you. Be sure to only have your ignition interlock device removed by a certified LifeSafer installer/provider.

I come here about once a month for maintenance, and every time the owner is there along with the rest of the crew. Everyone is always friendly, knowledgeable, and takes the time to answer any questions. It’s hard to find good people you can trust, and I’d definitely recommend this place to anyone looking for quality work and great service.
