There are ways to bypass the system, but without knowing what the correct resistance in the chip is, its not going to be easy or cheap.
There are a dozen or so different chips, each with a different resistance. The resistance completes the circuit for the VATS system sensor. You can buy a trick box to wire into the circuit, or have the computer changed to skip the VATS signal.
As long as the computer you have now does not get the signal from the VATS the injectors will not work.

    A push button will allow the engine to crank, but like I said before, without the resistance of the chip, its not likely you can get around the computer. And a remote start would still need the chip resistance or it would have a module that would have all 12 or 15 resistors built in. Most people actually tape a good key to the inside of the column to trick the sensor. But you still need the right key chip.

    If you could find a donor car with a computer and the keys you could switch them out.

    ok i went to the parts store and they have a bulldog remote start system and the first piece is a vats bypass module for the remote start is there a way to wire it in as primary ignition

    I've not used a remote start as the primary - I would think you would have to use the remote every time since the bypass would be powered by the remote system. If you do some internet searching you will find bypass modules much like the one you found without the remote feature. As far as I know they can be wired into the circuit. How long they last in daily use I don't know.

    thanks is is there a way to find out my key code since it does not match the vin

    I doubt the dealer would still have the equipment to scan the sensor on a model that old, but some locksmiths would have the equipment to do it. They have a device that jumpers the sensor in the cylinder with the 15 different resistors to find the right one. Or 15 blank keys one for each chip.

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.

My theft system is on and my 1997 cadillac deville will not start what can i do?

you will need to replace the vats lock cylinder and key. the wires break at the ignition switch. the new cylinder will come with a dummy key . you will need to get a new vats key cut to that blank. take yor old key or vin# to the dealership so they wil know what your vats# is.

I cannot locate the starter relay on my 1992 cadillac deville

this is a security system problem most likely and has nothing to do with any relay. You may have a defective VATS module or a defective VATS key sensor or a defective key, is the little piece of wire still embedded in the shaft of the key? VATS stands for Vehicle Anti Theft.
