Question about 1994 Cadillac DeVille

1 Answer

I just replced my starter in a 1994 Cadillac deville and we think it may be the security or theft system for the car. And, now the car will not start. And the dash says to "wait 3 minutes" and try again but when I try to turn it over it will not. How do I deal with this problem without having to go to a dealership or a shop?

OK. Make sure that the black and silver resistor on the key is clean of grease or moisture that can cause the security system to reject the key as a valid one coded for this car.

If you replaced the starter, hopefully you disconnected the battery first, so that there would not be any jolts of electricity or shorts when turning the wrenches or turning the bolts with the socket and ratchet.

I have a 1990 Cadillac Deville and a 1997 Cadillac Deville which have a similar key. Yours is probably similar in look and function to mine.

Another thing to mention, is that if you hear a click or it tries to turn over but doesn't, your connections may not be as good as they should be at the starter coming from the battery.

Or, finally, the starter might be defective, even though it is newly rebuilt or built.

So, I hope this helps.

1988 Cadillac DeVille


The 88 Deville is one of many cars made by GM that is using the antitheft system called VATS PASSKEY. (its that little black chip in the key) When this system fails, the car can't get the signal from the chip, so it locks out the starter to prevent theft. The car thinks it's being hot wired, so it shuts down. Look for a light on the dash that says SECURITY or ANTITHEFT. This is proof of a security failure. This might be your problem. This link explains more.

Can't get ignition starter switch to go on my 91 cadilac deville 870-688-8335


Do you see a light that says SECURITY on the dash somewhere? This can turn off your starter and disable your car. Read about it on this link with options on how to fix it yourself.

I bypassed the security system the car still want start I placed a hot wire directly on starter and the car turned over but there was no fuel going up what is the problem now


Try hooking the security system up again so that it's functional, then take out the fuse that's located on the fuse box in the trunk that's associated with the security system. It should be labeled "theft" and it's a 10amp fuse. The system will still function as normal only the horn will not sound if the security system is tripped and it will not shut down the fuel pump.

94 Cadillac deville will not start due to security system it states to take key out of ignition and try to restart in 3 minutes and still nothing I have replaced the starter and still nothing but...


this seems like the theft prevention system, same as on my dads cadi, the chip in the key may be bad,but this is an issue best resolved at a dealership. the computer may need replacing, but its about 1k. take it to a competant gm dealership.

Security system for automobile


u can't just clip the wire however you can install a resistor that equals the value of the key into the anti-theft module to bypass it.

I think its my starter or fuel pump, but not sure.


If your security light is on it may be your key that's preventing the car from starting. It's programmed with a code to prevent theft (Pass II theft deterrant system or something like that). So either the key is screwed up or the module that reads it is screwed up - either way it will disable your ignition.

Car wont start


as long as security theft system is on, car wont start.

don't you have the remote key to disable the theft system?

you can bypass security but you have to have wiring experience and splicing before you can proceed.
