2001 cadillac deville starting problem - YouTube

No. Disconnect battery for 3 hours to see if this helps. I admit I am not sure about this problem.

There is no unlock code - each radio is programmed with the VIN of the vehicle in which it was last installed. The only way to reprogram it to a different vehicle is with a Tech II scan tool (GM Dealer).

It's hard to say for sure since it sounds like it could be many things. If you turn the key and you hear a few clicks coming from the engine and then nothing, it could mean a very very weak battery. Your first step should be trying a different (fully charged) battery. Good luck.

This is just a guess, but try disconnecting the battery cables for a few minutes, then reconnect them and see if you can correct it.

Yes it will but your going to have to go tot he dealer to activate your radio. The radio is programed to work with the ECM's VIN number and replacing the radio with another radio will not recognize the Vin number and will not activate.
Thank you for using Fixya and good luck.

you will need to reenter your raido code

U will need to enter the radio anti theft code, this lock out was triggered by the loss of voltage to the radio during the battery change, this code is unique to each radio and cam in the owners information packet when the cat was sold new.

I've got a 97 deville d'elegance that has issues similar to these. Last year the red anti-theft light came on and the car wouldn't start-took it to the dealership and they replaced the PCM? (the main brain for the system) for $900...the guy told us the wiring was so corroded he didn't want to mess with it much. Today the message started flashing on the dash that says "anti-theft problem/ car may not restart" but it still turned over in the driveway a couple times so I am hoping I can reset it. The wiring system is jacked and will probably need to replace the wiring harness completely. Doubt its worth it. Not a secure feeling with 2 babies in the back seat in the middle of winter....
