Some Chevrolet Aveo models have a theft-deterrent feature built into the audio system. If the radio is removed from the car or the battery is disconnected, the radio will lock and will not be usable until an unlock code is entered. When you enter the code, you will reset the radio and restore it to its normal state. The code is provided by a Chevy dealer at the time the Aveo is purchased. If you do not have the code, contact a dealer so they can provide it for you.

Step 1

Turn the ignition switch to the “On” position.

Step 2

Press the power button on the radio. Wait for “Loc” to appear on the display.
