  • If that doesn't work, there is a TSB No.: 01-08-56-001A on this that identifies a problem with the Passlock sensor due to a faulty, broken or corroded wire in the connection between the sensor and the body control module.

    I would try the 30 minute relearn procedure below, otherwise it may have a Passlock Sensor failure or other anti-theft component failure...which will need to be scanned with a dealer level scan tool. There is no way to bypass this style of alarm system, and the keys are not programmable.

    1. Turn ON the ignition, with the engine OFF.
    2. Attempt to start the engine, then release the key to ON (vehicle will not start).
    3. Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF.
    4. Turn OFF the ignition, and wait 5 seconds .
    5. Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes (the vehicle is now ready to relearn the Passlock(TM) Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK). IMPORTANT: The vehicle learns the Passlock(TM) Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.
    6. Start the engine (the vehicle has now learned the Passlock(TM) Sensor Data Code and/or password).
    7. With a scan tool, clear any DTCs if needed (history DTCs will self clear after 100 ignition cycles).

    It seems logical that if you had an s-10 that had a passlock security system and an s-10 that did not have a passlock system then you would be able to convert one system to the other to cut the system off to start and run your truck.

    Everthing is an option package.
