Radio Theft-Deterrent Feature
WARNING: This page is about a different car, the 2003 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
Corvette radios come with the THEFTLOCK® radio security system. THEFTLOCK® is designed to discourage theft of the radio by using a secret code to disable all radio functions whenever battery power is removed.
The radio feature THEFTLOCK® may be used or ignored. If ignored, the system plays normally and the radio is not protected by this feature. If THEFTLOCK® is activated, the radio will not operate if stolen.
When THEFTLOCK® is activated, the radio will display LOC to indicate a locked condition anytime battery power is removed. If the system loses battery power for any reason the radio must be unlocked with the secret code before it will operate.
