I’ve never felt more compelled to make a positive review for a business. My experience with Juan at Imperial Audio in National City (SD) has been one to write home about. They are so helpful in helping to navigate my Lifesafer ignition interlock system. This whole debacle is already a big headache and a little kindness and compassion go a long way. I’ve had to cancel and reschedule appointment times (last minute) and risked getting a pricey infraction, Juan helped me understand the interlock system, facilitated my reschedule, explaining how the process worked, ultimately saving me a lot of anxiety and money. If you find yourself in a pickle and require this service, this is the place you want to go, trust me. In a world that seems relentlessly judgmental and disrespectful, it makes a huge difference to be met with kindness and understanding, especially in the wake of a perilous predicament. I’m so thankful to the Imperial Audio team!

How do I use my ignition interlock device?
During your appointment at LifeSafer, you'll receive comprehensive guidance on operating the LifeSafer ignition interlock device. 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.
