How to Reset an Anti-Theft Radio on a Chevy

General Motors vehicles, including Chevy, contain anti-theft Delco Theftlock radios that can only be used by entering the correct security code. This security code keeps someone from using the radio in another vehicle if the unique security code is not entered. The radio display will read "LOC" and the device will not turn on. Whenever your Chevy battery is disconnected or the battery dies, the Delco Theftlock radio enters the "LOC" mode. Follow these steps and you can reset the anti-theft radio and return the radio to a working state.

Step 1 - Turn the car ignition to the "ON" position.

Step 2 - Turn the radio off, if it is on.

Step 3 - Press and hold the "Minute" button on the radio faceplate.

Step 4 - Release the "Minute" button once "000" appears on the radio display.

Step 5 - Press the "Minute" button again until the last two digits of the security code for your radio is displayed.

Step 6 - Press the "Hour" button until the first two digits of the security code for your radio is displayed.

Step 7 - Press the "AM/FM" button until "SEC" appears on the radio display.

Press the "ON" button on the radio. The radio is now reset.

TIPS: Press the "Minute" and "Hour" buttons slowly until the security code matches. Going too fast may cause you to skip over the correct numbers of the security code. Store your radio security code in a safe place.
