Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** most likely means the Theft Deterrent Module has failed which is also known as the passlock sensor. This part is located near ignition switch and costs around $250 to have replaced at the dealership. Even without the remote everything should work normally. If car is not starting right now the only thing you can do is the 30 minute relearn procedure "let me know if you need procedure". Let me know if you have more questions or if there is anything else I can do to help. Thanks.
