Theft system will not go off
I have a 06 Cadillac cts the theft lock
comes on out the blue and will not turn off.
The key will get stuck in the ignition. I can
turn the car on and even put it in drive. Pls
I have an 07 Cadillac - same issue -- theft lock is on, cant turn key to "off" position - stops at accessory -- "service theft system" message comes up along with traction control icon -- makes no sense! -- a "mechanic" mentioned a non factory installed remote starter may be the problem -- still trying to get someone to disconnect that for me under dash -- very frustrating!!!!
I have an 06 CTS with exactly the same problem. Took it to dealership and they diognosed it as ECM gone and key lock cylinder. I have replaced the lock cylinder via locksmith, no change. New ECM comes tomorrow but I don't know if I can do the 10 minete programing when the key won't turn past ACC. I guess I'll find out if the ECM takes care of everything.
Sorry I forgot to update. ECM fixed all the problems and is still working just fine.
Bobby5876 Hey did you have to do the key relearn process once you replaced the ECM?? My car is throwing the anti theft crap and eats the key but will still start and run. Anyhow I was messing to know if I have to do the relearn process please let me know
Had same problem. Had to do the key relearn. After about 5 minutes my theftlock resets allowing access to systems & removal of the key. Replaced ECM & problem went away for awhile. Next step for me is the key identifier (ring around the key mounted on the ignition switch).
'06 CTS 3.6
