You can also expect them to share the same problems. Most years within a generation share the same parts and manufacturing process. This problem has popped up in the following Chevrolet generations. Generations Where This Problem Has Been Reported has a solution for how to fully bypass the PassLock system in GM cars. Replacement cylinder with new sensors can cost, with labor, as much as $450.īypassing the sensor will void any warranty, but since most of these vehicles are out-of-warranty at this point that might not be of any concern. Rinse, repeat, and cry.Ī more permanent solution is to either replace the ignition lock cylinder or bypass the sensor. When the light shuts off you can try to start the engine again. How to Fix Passlock for Chevy Vehicles ∞Ī temporary fix is to leave your key in the ignition, at the “auxiliary” position for about 10-15 minutes until the security light shuts off. A red (or yellow) “security” warning light will stay illuminated and the engine will either a) never start or b) start for a moment and then shut down. When the sensor defect starts, it usually presents itself as system fault code B2960. I’ll let you decide which one sounds more accurate. Others say their system is possessed by the devil and in need of an exorcist. Some have suggested that the pins in the system are “tin” plated and subject to oxidization over time. The short answer is there’s a problem with the sensor. When the key is inserted into the ignition, a magnet on the cylinder creates a signal to the ECM (engine control module) that essentially says everything is ok to start and run. Passlock uses a coded lock cylinder that essentially stops the engine from running until the proper key is detected. GM introduced many security systems – VATS, Passkey, Passlock, but if your GM has a key without a chip in it, chances are it’s passlock.
