Auto theft device activates on it's own car won't start. sit for 10 minutes with key on then it will start

A nice simple answer, you can't. Think of it this way, the car doesn't know you are the owner, and it is there to stop exactly what you are trying to do. You have two computer ECM and BCM, plus the antitheft module and a number of sensors all trying to stop you. All you have to do is the re-learn procedure. Plan B is an auto electrician or alarm / radio installer or auto locksmith.

30 Minute Re-Learn Procedure

1. Turn ON the ignition, with the engine OFF.
2. Attempt to start the engine, then release the key to ON (vehicle will not start).
3. Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF.
4. Turn OFF the ignition, and wait 5 seconds .

You can't bypass the anti-theft system. It is computer controlled and there to stop exactly what you are trying to do if you are trying to work a way around it..

If you just went out to the vehicle and you can't get in, or you put the keys in and the Security Light is flashing and won't let you start the car, there are re-learn procedures. This usually involves turning the key to the position before start, (dash warning lights on) and waiting for a chime or a light to flash (5 minutes), then you turn off and do the same again. You do it a third time and there is a chime and the Security Light goes off. A thief doesn't have 15 minutes to sit in the vehicle and wait.

Or

you need an auto-electrician to reprogram it.

Make sure battery is strong and try leaving key in on position for 5 to 15 minutes. Then go to start. This works on many vehicles - but many are different. If chip key and theft module working leaving key on for several minutes is supposed to be long enough to tell system vehicle is not being stolen (not many thieves willing to sit in car waiting for 10 minutes). If chip key or key "reader" has failed you need dealer help.

hmm your car has a problem with theft sistem or one of your theft modules is going out or wireing problem most likely some how you activeated your theft sistem only the dealer can help you on that they have to erase code and reprogram it othereby me saying modules i mean them antena on your colom your key or the theft module hope this helps im a auto repair mechanic no shop can help you ok

If you have a spare set of keys try using the different key. The identity chip in your key may be shorting.

Otherwise the "Reader" in your ignition switch may be cutting out. This puts it into an activation loop.

The late-90's GM Passlock system (e.g. 1997 Malibu, Regal, Impala, etc.) has a part around the ignition tumbler that goes bad and no longer reliably detects the valid key. In that situation, the "Theft System" light will slowly flash and the carburetor is cut off so the engine won't start. The time-out on the system is 10 minutes - you don't have to do anything, you don't have to disconnect the battery, the key can be out of the ignition -- it's just a time delay. After 10 minutes, the light goes out and you can try again (but if the key is again not detected, the light will start flashing again and you have to wait another 10 minutes)
Someone else, who had this problem, told me to remove all other keys from my keyring. The weight of the other keys pulls on the ignition key causing the key to be unreadable. It has been 7 weeks since I have been doing this and have not had a problem

usually a sign ur ignition switch is going bad and ur looking at about $200 cause the dealer has to recode it just a direction to look at its pretty common on those cars

I have a 97 Malibu and when the theft system light kept coming on and would only start after letting the car sit for 10 minutes we ended up replacing the complete ignition where the key goes in. Then it was fine. It wasn't cheap either. Sorry, good luck.
