How do you disable anti theft on a 2004 Pontiac grand am?

To disable the anti-theft system on a 2004 Pontiac Grand Am, you can try using the key fob to unlock the doors, as this often resets the system. If that doesn't work, you can insert the key into the ignition, turn it to the "On" position (not starting the engine), and leave it for about 10 minutes until the security light goes off. If you're still having trouble, consulting the owner's manual or contacting a professional locksmith or dealership may be necessary.
