Question
I drive a Cadillac Seville 1990.I put my key in the ignition and the car turned on but the engine wouldn't start. It said anti theft system remove key and wait 3 minutes.I did and tried again it said again anti theft system wait 3 minutes.How can I cut the anti theft system off so I can drive my car? I went to the passenger door and put the key in, I locked and unlocked it 4 times then I put the key in the ignition and it started.I drove around and took the key out and tried to restart it.The driver's information system said "wait 3 minutes due to anti theft system"

Answer
Ok then, from your desription and the
make/model/year of the car you have there,
it appears you've reset the VATS.

The car's security immobilizer
reader at the key switch
does not recognise the coded
chip in the ignition key any longer.

You can try to put the key
in the ignition, turn to the on position &
wait at least 10 mins like that.
(Do not turn off the key switch before
10 minutes as elapsed!)

Once done, the key is re-programmed and
should allow the fuel injectors to work again.
The car would start now if corrected.

In some cases, the VATS (GM'S VEHICLE ANTI THEFT SYSTEM)
will re learn the code this way, and will then
allow the restart, however if this does not work,
then you can simply tow it to any GM vehicle dealer
to have the service department re code it.

There is a permanent solution though.
Adding the PLJX Self learning Bypass module (69.95)
will bypass the PASSLOCK system in your vehicle
for good. See this at www.PASSLOCK1.com

Good luck I hope method 1 does the trick!
