How do u disable a 94 cadillac deville anti theft system

U can bypass it (called the VATS system) but not fully disable it, what is done mimics the key code to fool the VATS module into sending a OK to start signal to the fuel injection computer (called the ECM). go to the web link below for instructions on the bypass.

Hi,

You can disable the 94 cadillac deville anti theft system either by the remote module or by using the door key, and turning the door outside lock cylinder.

Best regards.
