Transponder Programming: Notes

NOTE: After a SKREEM/WCM is replaced, the ignition/transponder keys need to be programmed to the new SKREEM/WCM. Follow the directions on the diagnostic scan tool. The transponder key for the SKREES/SKIM and the RKE will both be programmed during this operation. There is no need to program the fob of the key for RKE functionality once the transponder key is programmed to the new SKREEM/WCM.

NOTE: When a PCM and the SKREEM/WCM are replaced at the same time, perform the following steps in order:

Program the new PCM.
Program the new SKREEM/WCM.
Program all ignition/transponder keys to the new SKREEM/WCM.

. Refer to STANDARD PROCEDURE .

All Sentry Keys included with the vehicle are pre-programmed to work with the Sentry Key Remote Entry System (SKREES), sometimes referred to as the Sentry Key Immobilizer System (SKIS), when it is shipped from the factory. The Sentry Key Remote Entry Module (SKREEM), sometimes referred to as the Wireless Control Module (WCM), can be programmed to recognize up to a total of eight Sentry Keys. When programming a blank Sentry Key transponder, the key must first be cut to match the ignition switch lock cylinder in the vehicle for which it will be used. Once the additional or new key has been cut, the SKREEM/WCM must be programmed to recognize it as a valid key. There are two possible methods to program the SKREEM/WCM to recognize a new or additional valid key, the Secured Access Method and the Customer Learn Method. Following are the details of these two programming methods.
