F. Program the WIN Receiver
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 WIN is replaced, it is necessary to program the Secret Key Code into the new module using a diagnostic scan tool.NOTE:
Programming the WIN is done using a diagnostic scan tool and the vehicle's 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 the "lockout mode," place the ignition in the "RUN" position for one hour and then enter the correct PIN. Be certain that all accessories are turned OFF and the left front door is open for the entire hour. Also, monitor the battery state and connect a battery charger if necessary.
1. Connect a battery charger to the vehicle.
2. Connect the wiTECH scan tool.
NOTE:
Have the vehicle's PIN readily available before running the routine.
3. Starting at the "Vehicle View" screen, select "WCM/WIN".

5. Select "WIN Replaced".
6. Enter the PIN when prompted.
