The Pontiac Grand Prix 2003 uses a PASS-Key III system, which is a personalized automotive security system. This security system is activated when someone attempts to open the vehicle with the wrong key. Upon detection, the system turns off the vehicle's starter and fuel system, preventing the engine from running. You may need to reset the security system to program it for a new key.

Step 1

Put the key into the ignition and turn it clockwise. The engine should start and the security light should come on.

Step 2

Turn the ignition counterclockwise and turn it on again if the security light doesn't appear. It may have been damaged somehow if the light isn't displayed.

Step 3

Insert the original key into the ignition and turn clockwise to turn on the engine. If you don't have the original, you will have to go to your GM service shop to obtain a new one.

Step 4

Turn the key to "Off" and remove the key.

Step 5

Insert the key that you want to program and turn it to "RUN" within five seconds of removing the original key. The security light will turn off to indicate that the key and security system has been reset.
