What is passlock on GM cars?

The PassLock system was designed to prevent vehicle theft by disabling fuel to the engine if attempts are made to start the vehicle without the correct bitted key. PASSLock increased the level of security while retaining the ease of service and costs offered by standard ignition lock systems.

Why did GM change to a PassLock system?

The first generation PassKey systems incorporated a resistor pellet into the head of the key. The resistor made contact with terminals in the lock cylinder and the system read the resistance value of the resistor pellet. These systems had a high failure rate, so GM changed to the PassLock system.

How often does a GM PassLock light flash?

You need a scan tool. If the signal is not correct, the PCM disables the injector and the starter and flashes the light once per second. If an illegitimate key is used or a system problem exists, the light flashes twice per second. This system allows starter operation, then kills the injectors 1-2 seconds after startup.
