What does an interlock cost?

Don't pay two companies for one service!  Lifesafer is the only provider in California that includes calibration, installation, and equipment rental on an ignition interlock for one monthly cost.  Our competitors will send you to mechanics that will charge you separately.

We stand by our price.  We charge one monthly fee of $92.  If you find a better deal on an ignition interlock we will match their price and give you a $25 credit.  This includes all required services for the interlock:  installation, calibration, as well as court and DMV paperwork,  are included.
