Just to reiterate, so you have this in writing:

30 Minute Learn Procedure

Important: The vehicle learns the Passlock™ Sensor Data Code and/or password ***** the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.

  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™ Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK).
  6. Start the engine (the vehicle has now learned the Passlock™ 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).

Let me know how it turns out!
