Well it has passlock two and this is common with these cars. never seen the other issue to accompany it but if you do a relearn of the key and it starts then it could be two different issue's but if it don't work then they are related.

a relearn of the key is done with the ebrake up to keep the day time running lights off ( not an issue for you) but do it anyway. put key in the ignition and turn it to the on postion right before crank for 10 sec. turn it off for 10 sec. then turn it back on for 10 mins. repeat two more times back off for 10 sec. and then back on for 10 mins. it is cruishle you try to keep with in the times or very close. 10 seconds and 10 minuites three times and that will relearn the key and if it starts then you may have two issue's but hard to tell with out testing. but i think this is the best thing you can do for now.

i have a customer that can't afford the passlock module and labor so i taught her this and she is better then me now at it. lol... but like i said very common issue. let me know if you have any more question. good luck

SOURCE: 1998 ford expedition wont start. theft like is

If you are reseting a factory alarm...lock and unlock the drivers door with the key. If you don't know the code look under the dash driver side in left corner there should be a black cover with a sticker with a code on it 6 numbers that is the factory code.

1997 Chevy Cavalier. How do I bypass the anti-theft system forever?

Question edited for clarity and correct name of vehicle.

You can't bypass it Cherie, it involves transponder chips, receivers and the engine computer (ECM).. The anti-theft system is there to stop theft of the vehicle, basically what you are trying to do. You have to fix the system, not find a way around it. This is the reset. As long as you battery is good and fully charged, it should only need doing once.

Just leave the key in the run position and the "Theft System " light on the dash will be flashing. Leave the key on for about 10 minutes and the light will stop flashing and go on solid. Then the theft system is disable.

I have a 1998 chevy cavalier LS and my car will crank but it shuts off after about a second. i've heard that its the theft system shuttin it off. is there a way to do it without going to the deale

If the theft was the culprit,the security light would be flashing and the car would not start at all. I would check fuel pressure first,might want that ecm to be flashed for the car that it is in.

The 'theft system' light does not turn off with the key in the run position on my 1999 chevy cavalier. car won't start, it won't even crank over. the battery and the starter are brand

try locking your car with the key and unlocking it with the key, leave it for 30 second or so between the locking and unlocking , the car thinks some one has tampered with it

It is probably not the anti theft system if it cranks over fast then slow it is your timing chain. If you want to try resetting the anti theft system disconnect the battery cables for 24 hours and reconnect them.
