30-Minute Vehicle Key Relearn
This 30-minute learn procedure should be used when all vehicle keys are desired to be replaced or reprogrammed. This procedure will erase all previously learned vehicle keys from the TDM. Once the 30-minute learn procedure has been completed, any remaining vehicle keys may be programmed using the Adding Keys procedure to ensure their continued functionality.
- With an unlearned master vehicle key, turn ON the ignition, with the engine OFF.
- Observe the security indicator, after approximately 10 minutes the telltale will turn off.
- Turn OFF the ignition, and wait 5 seconds.
- Repeat steps Β 1-Β 3 two more times for a total of 3 cycles or 30 minutes.NOTE: The TDM learns the key transponder information upon the ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.
- With a master vehicle key, start the vehicle. The vehicle has now learned the key transponder information.
- If additional keys are required to be learned, refer to ADDING KEYSΒ .
- With a scan tool, clear any DTCs.
