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.

They completed the IID installation in the allotted time period, and their onboarding/training in how to use the device was thorough. The only negative part of this experience was that Cambridge Sound and Security charged me $250 for the installation fee, when the LifeSafer agent who scheduled the appointment for me told me it would only be $170.

This includes instructions on proper usage, what to avoid prior to using the device, and tips for ensuring it operates effectively. Please do not hesitate to ask your certified installer any questions you may have about your car breathalyzer and our services.
How much does an ignition interlock device cost?
The cost for installing a LifeSafer ignition interlock device, also known as a car breathalyzer, usually ranges from $70 to $150. This is a one-time installation fee that you'll pay at the beginning of your lease period for the device. You'll pay this fee directly to the service center that installs the device in your vehicle. Additional fees are usually incurred every time you must have your device calibrated and vary by state.
How does an interlock device/car breathalyzer work?
After the device is set up, drivers need to breathe into the car breathalyzer's mouthpiece to provide a sample. This device checks the driver’s breath alcohol concentration (BAC) to measure it is within legal limits. Typically, if the BAC is below .025, the driver is then clear to insert their keys and start the vehicle.
