PASS-Key@I1 Your vehicle is equipped with the PASS-Key I1 (Personalized Automotive Security System) theft-deterrent system. PASS-Key I1 is a passive theft-deterrent system. It works when you insert or remove the key from the ignition. PASS-Key I1 uses a resistor pellet in the ignition key that matches a decoder in your vehicle. When the PASS-Key I1 system senses that someone is using the wrong key,it shuts downthe vehicle's starter and fuel systems. For about three minutes, the starter won't work and fuel won'tgo to the engine.If someone tries to start your vehicle againor uses anotherkey during this time, the vehicle will not start.This discourages someone from randomly trying differentkeys with different resistor pellets in an attempt to make a match. Clean and dry the key. Wait about threeminutes and try again. If the starter still won't work, and the key appears to be cleanand dry, wait about three minutes and try another ignition key. At this time,you may also want to check the fuse (see "Fuses and Circuit Breakers'' in the Index). If the starter won't work with the other key, your vehicle needs service. If your vehicle does start, the first ignition key may be faulty. See your Buick dealer or a locksmith who can service the PASS-Key 11. If you accidentally use a key that has a damaged or missing resistor pellet, the starter won't work and the SECURITY light will come on. But you don't have to wait three minutes before trying another ignition key. See your Buick dealer or a locksmith who can service the PASS-Key I1 to have a new key made. If you're ever driving and SECURITY light comes on, you will be able to restart your engine if you turn it off.
