Theft-Deterrent Feature
THEFTLOCK® is designed to discourage theft of your vehicle’s radio. The feature works automatically by learning a portion of the Vehicle Identification Number (VIN). If the radio is moved to a different vehicle, it does not operate and LOCKED displays.
When the radio and vehicle are turned off, the blinking red light indicates that THEFTLOCK® is armed.
With THEFTLOCK® activated, the radio does not operate if stolen.
