2006 cadillac sts I swapped radio for navigation unit and it says theftlock protection activated anyone know how to fix this if it can be fixed


I have a scanner that does this for domestic vehicles, I do them for free. Just for extra work, the harder jobs. I work at a shop that can't, but they want to charge and not give me anything , so I don't do it for them. Some garages have them though. But dealer is the most likely spot. Usually around $50.

1997 cadillac deville theftlock activated bose stereo


There should be a code in your manual in the section about the radio, or in the section about electrical maintenance. This lockout is triggered every time the battery is disconnected.

I need a radio code to unlock gm part 10356164


Your '05 is too new to unlock on your own.

There are 2 types of GM Theftlock, Theftlock I and Theftlock II. The Theftlock I is found in pre 2000 vehicles, and Theftlock II is in the later models.


Theftlock I - Uses a volatile user settable code that is input through the key pad on the front of the Radio. If the power is lost (dead battery etc.) the code is gone and must be re-entered for the radio to work. But with the correct procedure the owner can unlock it.

Theftlock II - Uses an EPROM (erasable/programmable read only memory) or a PROM (the difference is you can not alter the prom once it is programmed).

In either case the code is burned in and holds even when the power is lost. With Theftlock II the radio is married to the vehicle by way of the VIN. When the vehicle is started the computer compares the number in the radio with the VIN in the body control module. If they match, the radio works, if not the radio displays LOC and you are finished, there is no easy way around it. The radio will not work until you make a trip to the dealer.

The dealer will use a TECH 2 scanner to change the VIN stored in the radio. The radio does not need to be removed (for the serial number or any other nonsense). The technician just plugs into the computer and resets the VIN in the radio.

Thank you for using fixya and keep us posted.

After my husband changed the battery in my STS, the CD player will not work. I have 3 CD's loaded in the player. It will not play or eject.


You need enter the unlock CODE for extract your CDs; check in your owners manual (any label in the last page .

THEFTLOCK is designed to discourage theft of your vehicle’s radio. The feature works automatically by learning a portion of the Vehicle Identification Number (VIN). If the radio is moved to a different vehicle, it will not operate. If the radio is removed from your vehicle, the original VIN in the radio can be used to trace the radio back to your vehicle.

With THEFTLOCK® activated, the radio will not operate if stolen.

Hope helps.

I just bought another factory radio/CD player for my 2005 Cadillac CTS. The installed cd player is inop. When I installed the new unit, I get "Theftlock" on the screen. How dod I reset the radio?


Hopefully you got the unlock code with it, otherwise, write down serial number and model number off back or side of deck, and give dealer a call, they should be able to give you the code .
