My anti theft message is on in my 1999 Cadillac deville, how do I reset it ?

You need to connect and OBDII code reader to the car. The anti theft system communicates with the car's computer. Turn the ignition key to accessories, and allow the code reader to read for Diagnostic Trouble Codes (DTC's). Any DTC's connected with your theft deterrent system will show up. Reset the codes to remove the theft message from your car. This cannot be done without an OBDII scanner.
