Question about 1994 Cadillac DeVille

1994 cadillace anti theft system

I go to start the car and the dash board reads that the ignition as been disabled due to the anti theft system in the car. Also a "Security" light keeps flashing. I tried disconnecting the battery and relpacing the fuse that powers the anti theft system and nothing works the car will not start. I do not have any aftermarket theft system at all. Is there a way to bypass this or disarm it?

I just had this same problem with a '96 . do you have a vats key in your '94? you need to bypass the VATS system. read some of the blogs on this site and it will tell you how to do it. I fixed mine with a $2 resistor from radio shack.

97 cutless supreme it will start and only run about 10 seconds then die

Does it have anti-theft system ?
The vehicle theft deterrent system is designed in order to prevent vehicle theft by disabling the fuel injectors unless the lock cylinder is correctly engaged by a mechanical key. The theft deterrent system uses the following 4 components for theft prevention:
• The lock cylinder
• The ignition switch
• The body control module (BCM)
• The powertrain control module (PCM) Do you have a SECURITY light lit on the dash ?

I have a 03 cavalier it starts up then shuts back off what causes it

Hi Missy , There are a number of thing's that can cause this . Fuel system problems , ignition system problems , the PCM - powertrain control module , the PCM is the engine computer ! There are multiple sensors on this vehicle as with all cars for the 80's on . From 1996 on they have more electronic modules then before , Anti-theft systems , air bags, anti - lock brakes etc.
Does you car have any lights light on the dash ? check engine ? Security ?. When you first turn on your key the dash lights light up an after 7 seconds the lights should go out , Do they ? You should check for DTC's - diagnostic trouble codes . That means hooking your car up to a scan tool . If it starts an shuts back off right away I would think a anti-theft system problem . If the anti-theft thinks it being stolen it disables the fuel injection in some cases !

Find unit under dash ( if you can), trace wires from ignition and bypass (jump) before to after unit, disables security but led light still flashes, you can then at least drive to a service centre.

89 firebird anti theft code won't let car start

If code 53 involves the PASS system for your car, the chip in the key has failed, or the sensor in the lock cylinder, or the control module.
The anti-theft system disables the starter and the fuel injectors. You could bypass those circuits to get the car started.

Starting: car will not start; dash reads "starting

Hello, RW Betton,

Here is a few things to try then please read toward the bottom. Please read my whole page here of ideas for you.

Question? when it does disable it usually will say " starting disabled due to theft system remove key from ignition and wait 3 minutes'. Are you able to start car after the 3 minutes? or it wont period? My car does this a lot to but I think its cause you have to unlock the car, get in it, shut the doors and then start the car because mine does it when i open the doors.

Also some times if you have a chip in your key will do this as they ware out, and would have to try you back up key (if you have one) and if turns out to be your key, that has bad chip, dealer would have to replace that.

Finally, this is your other choice as well below, and you can click on that site and it should help you. Most the times this whole issue is triggered from the key itself into the ignition, that cause this.

If you have the GM pass lock system in that car, this is a site that will show you how to disable it:

However, if it were my car I would see what the dealer will charge to fix it first. It may just be a simple reprogramming is needed or a inched wire in the steering column. I would want the car to have an anti theft system working as it should.

I hope my free advice has helped you, and if you could please rate my help accordingly and some kind words too. I appreciate it, and keep me informed on progress. Here is also my direct link for all my services I offer to help you.

That is my personal page of all my areas of ads of my expertize. Mike

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.

Dash dead ,turn key nothing happens,no click,battery good,ignition switch is new,starter turns over when jumped with screwdriver,lights,horn,

It there is a problem with the dash, there is probably no power to the anti theft module in your ignition. The car is in anti theft mode due to not being able to read your key transponder. Basically if it cant read the key, it thinks its being stolen. Either fix the dash lights, or fully bypass the security. All the security info you need is on here including how to bypass it.
