Is there a problem with the PassLock sensor?
The short answer is there’s a problem with the sensor. Some have suggested that the pins in the system are “tin” plated and subject to oxidization over time. Others say their system is possessed by the devil and in need of an exorcist.
What do I need to fix my PassLock security system?
The fault is almost always in the lock cylinder case sensor or the wires from the lock cylinder case to the BCM connector. The fix is to install a new lock cylinder. Pros: Cheap. You just need resistors
What is the system fault code for PassLock security?
When the sensor defect starts, it usually presents itself as system fault code B2960. 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.
How does the PassLock security system work on a car?
When you insert the key and rotate the lock cylinder, a magnet passes by a sensor and the sensor sends a voltage to the body control module (BCM). The BCM has been programmed to expect a certain voltage. If it receives the expected voltage, it sends a start signal to the PCM.

What happens if you have the wrong PassLock code?
Also, the ignition lock cylinder must be rotated to the “crank” position. If the incorrect code is read, the system will not allow the engine to start for four minutes—even if the correct code is received. The security light will remain on or a message will be displayed on the Driver Information Center (depending on the model) when this occurs.
