Question about 1999 Cadillac DeVille
1999 deville ran fine now wont start. dash says security system problem car may not restart any ideas?
Had the same problem, a service guy at the dealer soldered a fuse between the ignition wires. Never had a problem again. The problem is the keys, they have a resistor on the key, if the ignition doesnt detect the right resistance it will not unlock the security system. The fuse allows the system to always read resistance in the ignition system. Seriously I could not make something that silly up, but the fuse worked. 5 years not a problem
