need to reprogram ignition key security system when battery disconnected. turn ignition key to the on position for 3 to 10 seconds until the lock light goes out then start vechicle.if lock light dont turn off turn ignition switch to on position 30 seconds until lock light turn off.

you need to replace your switch the theft system is activated with the key maybe try putting the key close to where it goes

Your vehicle security system has malfunctioned, you need to have it taken to the dealer for testing with a special tool called a "TECH2 scanner. There may be a service bulletin on this problem and you may be able to get help from GM on the repair.

abs light means anti lock brake system and the light is telling you that they aren't working properly. you still have brakes it just won't be with the anti lock system your vehicle has. you will need to have your brake system checked out.

If the passkey is messed up, there will be a light on the dash that says security, or have a picture of a car with a lock thru it. If there is no light when the key is turned forward, then its NOT a passkey problem.
