Understanding the Radio Lock Feature
The GM radio’s Theftlock system triggers a security lockout if the unit loses power or is removed from the vehicle, necessitating a specific code to regain functionality. When you re-establish power or reinstall the radio, the display will read LOC, indicating the Theftlock system is active.
To unlock your GM radio, you’ll need to retrieve the six-digit serial number and contact a GM dealer for the four-digit radio unlock code.
Once obtained, enter the radio code using the Hour and Minute buttons. Press and hold the preset buttons as instructed to confirm the code. If correct, the radio will display ‘SEC,’ signifying a successful unlock.
Locating Your Radio’s Security Code
To locate your GM radio’s security code, start your vehicle and activate the radio system. If the display reads ‘LOC,’ your radio features the Theftlock system. Quickly press and hold presets 2 and 3 until the radio’s display shows a three-digit code. Write this down immediately.
Next, press the AM/FM button; a second three-digit code will appear. Note this down as well—you now have a six-digit code unique to your radio.
Contact the Chevy Radio Code phone line at 1-800-537-5140. Input 106010, followed by the # key. Then, enter your six-digit code, followed by the * key. The system will provide you with a four-digit security code. Write it down; this code will unlock your radio.
If you encounter issues, contact your local GM or Chevy dealer for assistance.
Inputting the Unlock Code Correctly
Having located your GM radio’s security code, you’ll now need to input this code carefully to unlock the radio successfully. Ensure you enter the four-digit radio code accurately to avoid triggering the Theftlock system. Here’s a table to guide you through the process:
| Step | Action | Display |
|---|---|---|
| 1 | Turn the ignition to “ON” position | Radio display should be on |
| 2 | Press and hold presets | Enter unlock mode |
| 3 | Input the first digit | Press corresponding button |
| 4 | Repeat for remaining digits | Input each digit in sequence |
Contacting GM for Assistance
Should you encounter difficulty unlocking your 2012 GM radio, consider calling the Chevy Radio Code support line at 1-800-537-5140 for guidance. The specialists on the Radio Code phone line understand the intricacies of Theftlock radios which render them inoperable without a proper code. When you call the Chevy Radio Code support, be ready to provide the six-digit radio identification number.
If the phone line can’t resolve your issue, contact your local GM Dealer and give them the identification number. They’ll assist with radio code retrieval, typically offering the service for free or a nominal charge. Be wary if a dealer is charging an exorbitant fee; you might find better alternatives online or at another local GM Dealer.
Preventing Future Radio Lockouts
While obtaining your radio code can resolve current lockouts, it’s crucial to take steps to prevent similar issues in the future. Be aware that the Theftlock system only allows a specific radio code to deactivate the security feature. Vehicles both feature Theftlock radios, so it’s imperative to keep this code handy.
To prevent future radio lockouts, write the code down in a secure location. Consider using a permanent marker to note the code inside your owner’s manual or on a card in your vehicle.
Should you need to enter the number again, such as after a battery disconnection or if you Unlock Your Chevy, the code will be readily accessible. If you sell the car, pass the code along to avoid inconvenience for the new owner.
Always have the radio hotline number available for urgent queries.
Conclusion
Now that you’ve unlocked your 2012 GM radio, keep your security code handy to prevent future lockouts.
Should issues arise, don’t hesitate to call GM for support.
Remember, proper input of your unique code is crucial for access to your stereo.
