How to Unlock the Car Radio on a Buick Regalby David Clair
Some models of the Buick Regal are equipped with a radio anti-theft system that locks the audio system if it is removed from the car or if the battery is disconnected. A locked radio is disabled until its unique security code is entered. The security code was issued with the Regal when it was first sold. If you no longer have the code, you can obtain it by contacting a Buick dealer.
Turn the ignition switch to "On." Do not start the engine.
Press the "Power" button on the radio to turn it on. Wait for "LOC" to appear on the display.
Press the "MIN" clock-setting button repeatedly until the last two digits of your code are displayed.
Press the "HR" clock-setting button repeatedly until the first two digits of your code are displayed.
Press the "AM/FM" button to submit the code. The radio unlocks if the code is accepted.
