How to Reset the Passlock System on a 2000 Silverado

by David Clair

The 2000 Chevrolet Silverado is equipped with the General Motors Passlock theft-deterrent security system. The system disables fuel to the ignition if a valid key is not used when attempting to start the engine. If the Passlock system is activated, the Silverado will not be able to be started until the system is reset. When the system is activated, a "Security" message appears on the instrument panel.

Insert the key into the ignition. Attempt to start the engine. If the Passlock system identifies the key as unauthorized, the engine stalls.

Leave the ignition switch in the "Run" position as the "Security" light blinks on and off for approximately 10 minutes.

Turn the ignition switch clockwise to start the engine immediately after the "Security" light stops flashing. The Passlock system resets and the engine will start.
