Programming Ignition Keys To The SKREEM

Each ignition key transponder also has a unique ID code that is assigned at the time the key is manufactured. When a key is programmed into the SKREEM/WCM, the transponder ID code is learned by the module and the transponder acquires the unique Secret Key ID code from the SKREEM/WCM. To program ignition keys into the SKREEM/WCM, follow the programming steps outlined in the diagnostic scan tool for "Program Ignition Keys or Key FOBs" under "Miscellaneous Functions" for the "WCM/Wireless Control Module" menu item.

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

If ignition key programming is unsuccessful, the scan tool will display one of the following error messages:

Programming Not Attempted - The scan tool attempts to read the programmed key status and there are no keys programmed into SKREEM memory.
Programming Key Failed (Possible Used Key From Wrong Vehicle) - SKREEM is unable to program an ignition key transponder due to one of the following:
- The ignition key transponder is faulty.
- The ignition key transponder is or has been already programmed to another vehicle.
8 Keys Already Learned, Programming Not Done - The SKREEM transponder ID memory is full.
Learned Key In Ignition - The ID for the ignition key transponder currently in the ignition lock cylinder is already programmed into SKREEM memory.
