Have you tried resetting the alarm by locking and unlocking the drivers side door?If you do this a couple of times in some cars it will restet the factory security system and allow the key to work again

Some ignition keys have a resistor built into them and the cars computer is programmed to that resistance. The security system needs to verify the resistance for the key before it will let the car start. What I have read recently about this subject basically states that if you are having problems with a car not starting, won't turn over, no clicking but the car still has power....and everything seems fine in the car....battery, starter, alternator, etc. but the security light comes on in the car and the car eventually does start usually 5 minutes or so later then it is the cars security system that is causing the problem. It doesn't recognize the resistance of the key. It sounds like the security system needs to be replaced or bypassed. A friend of mine has a '94 olds royale 88 that started having this problem a few months ago. The car isn't fixed yet but that is just because I just found this information on the security systems on the internet a few days ago. It looks like it is a somewhat common problem with some of the cars that GM made when they first started installing the Passkey I, II and III systems into their vehicles. I and if someone else has more information on this subject I would be interested in hearing about it.

its not the drivers side door lock the car with the remote . go to pass side and manula uulock door. that should rest it

You should check the ignition key switch on the steering colum it will have one of the two wires broken.This sets off the security system which kills the ignition and the fuel pump system.When replacing the key switch make sure you buy one from the dealer most aftermarket switchs are poor quality and if go through the trouble of taking the steering wheel off and parts of the colum do the job right the first time.After you put the new key switch in remember to connect the two wires in the correct electrical terminal.Turn the key to the on position and wait about 10-20 minutes for your computer to recongnize the new switch and program it into it's memory and your car should start right up.
