Programming Ignition Keys To The Win: Notes

The secret key is an ID code that is unique to each WIN. This code is programmed and stored in the WIN, the PCM, and each ignition key transponder chip. When the PCM or WIN is replaced, it is necessary to program the Secret Key Code into the new module using a diagnostic scan tool. Follow the programming steps outlined in the diagnostic scan tool for PCM REPLACED  , WIN REPLACED  , or TIPM REPLACED  under MISCELLANEOUS FUNCTIONS  for the WIRELESS CONTROL MODULE  menu item as appropriate.

NOTE:

Programming the PCM or WIN is done using a diagnostic scan tool and a PIN to enter secure access mode. If three attempts are made to enter secure access mode using an incorrect PIN, secure access mode will be locked out for one hour. To exit this lockout mode, turn the ignition to the RUN position for one hour and then enter the correct PIN. Be certain that all accessories are turned OFF. Also, monitor the battery state and connect a battery charger if necessary.

Each FOBIK has a unique ID code that is assigned at the time the key is manufactured. When a key is programmed into the WIN, the module learns the transponder ID code and the transponder acquires the unique Secret Key ID code from the WIN.

CAUTION:

Read all notes and cautions for programming procedures.

NOTE:

If you are also replacing the PCM and/or WCM/WIN, refer to the module/programming order replacement guide before starting. Refer to STANDARD PROCEDURE  .

  1. Connect a battery charger to the vehicle.
  2. Connect the scan tool.
  3. Have a unique vehicle PIN readily available before running the routine.
  4. Ignition key should be in RUN position.
  5. Select "ECU View".
  6. Select "WIN Wireless Control".
  7. Select "Miscellaneous Functions."
  8. Select "Program Ignition Keys or Key FOBs", Start
  9. Enter the PIN when prompted.
  10. Verify the correct information.
  11. Cycle ignition key after the successful routine completion.
NOTE:

If the original keys do not successfully program to the new WIN after the proper procedures are followed correctly, programming new keys will be necessary.

NOTE:

A maximum of eight keys can be learned by the WIN. Once a key is learned by a WIN, that key has acquired the Secret Key for that WIN and cannot be transferred to any other WIN or vehicle.
