    If this is the case you have a fault in the system and need the GM dealer to scan the Passkey module for fault codes.

2000 grand am security light comes on can i bypass that with remote start


Are you the one who bought the vehicle new ? Replaced ignition switch or the ignition lock cylinder ? No , sorry, but a remote start will not by pass 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)
When starting the engine, the PCM searches for a password from the BCM through the Class 2 serial data circuit. If the password is not recognized or not present, the PCM will disable the engine. Two modes of tamper detection are provided:
No password received
The engine will start and stall quickly. SECURITY telltale will flash on the instrument panel cluster (IPC) and then stay ON steady.
Incorrect or disable password received (More than 3 invalid passwords are received)
The engine is disabled for at least 10 minutes and the SECURITY telltale will illuminate solid on the IPC during the 10 minutes.
After the vehicle has passed theft detection, the PCM will continue normal operation.

Disable alarm


Its not a wire. The anti-theft system is part of the engine computer.
If locking and unlocking the driver's door does not help, you'll need to get the system checked out. It could be the chip in the key, or several other components.

you cant. the wcm which is the wireless control module can not be by passed. it keeps the tipm which is the total intregated power module from allowing the asd auto shut down relay from letting the vehicle start. you have to tow it to a dealer or a shop that has the wi-tech.

the problem seems to be the door switches which are not working giving fasle alarm to anti theft device. use contact cleaners on the door switch with the cabin light active on door open. you may then evaluate wether working or not. check all the doors one by one

Trouble starting once in awhile


it does sound like the anti-theft system. There are only 2 ways to bypass your problem. 1) disconnect the anti-theft system which runs into your ignition, cut the wires to the system and join them back together without hooking it back up to the anti-theft. 2) Bring it back to the dealer so that they can replace your anti-theft sensor. The part is rather cheap but the labor is the killer.
