Programming Ignition Keys To The SKREEM/WCM

WARNING: This page is about a different car, the 2006 Dodge Grand Caravan, 2006 Dodge Caravan, and 2006 Chrysler Town & Country. However, it is still accessible from the selected car via links, so may be relevant.

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/WCM. Once a key is learned to a SKREEM/WCM, that key has acquired the Secret Key for that SKREEM/WCM and cannot be used on any other vehicle at the same time.

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/WCM is unable to program an ignition key transponder due to one of the following:
1. The ignition key transponder is faulty.
2. The ignition key transponder is or has been already programmed to another vehicle.
8 Keys Already Learned, Programming Not Done - The SKREEM/FCM 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/WCM memory.
