My 99 Deville with 135,000 would not start this morning. No symptoms or problems til this morning. Got the message"THEFT SYSTEM PROBLEM CAR MAY NOT START". Codes are: B0533, B2471, B2750, C1276, U1016, U1255.
Looks like the passkey is messed up. Any ideas or suggestions? I tried both of my keys too.
Happy New Year,
Bill.

Somebody should beat me over the head with an old heater hose! After spending 2 hours with the bypass and $80 for a new battery I replaced a 10 amp fuse and she popped right off. CHECK THE FUSES FIRST YOU IDIOT!!!!
