Programming The Secret Key To The Win

2009 Jeep Grand Cherokee SRT-8SECTION Programming The Secret Key To The Win

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.
