ALL Keys Lost (Domestic)

If you have lost all the keys that the VTD module has learned, the PASS-Key III module can be reprogrammed to learn 10 new keys. This procedure will take 30 minutes to complete.

  1. Cut the new key with the mechanical key code for the vehicle.
  2. Insert the new key in the ignition and turn the ignition ON.
  3. The PASS KEY telltale will flash at 1 Hz.
  4. Leave the key ON in this state for 10 minutes.
  5. After 10 minutes, turn the key OFF and then back ON within 10 seconds.
  6. Repeat steps 4 and 5, for a total of 3 ignition key cycles.
  7. After the third ignition key cycle 10 minute time period has elapsed the PASS KEY telltale stops flashing and the new key has been learned.

This procedure will reset the valid key code counter to 1. To program more keys, refer to Learn More Keys Mode.
