Welcome to Norcal Interlock

Thank you for visiting NorCal Interlock. We appreciate your business.

NorCal Interlock is located in Roseville, Ca and services customers in the greater Sacramento area (Sacramento and Placer Counties). We specialize in ignition interlock device installation on your vehicle, when required by the State of California and the Department of Motor Vehicles. An Ignition Interlock Device prevents a driver from starting a motor vehicle until a breath alcohol test is passed. This is also known as an in-car breathalyzer.

We look forward to working with you.
