Programming Ignition Keys To The WCM

WARNING: This page is about a different car, the 2017 Jeep Patriot and 2017 Jeep Compass. 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 WCM, the transponder ID code is learned by the module and the transponder acquires the unique Secret Key ID code from the WCM. To program ignition keys into the WCM, follow the programming steps outlined in the diagnostic scan tool for PROGRAM IGNITION KEYS OR KEY FOBS under MISCELLANEOUS FUNCTIONS for the WIRELESS CONTROL MODULE/WCM menu item.

NOTE:

If the original keys do not successfully program to the new WCM after the proper procedures are followed correctly, programming new keys will be necessary.

NOTE:

A maximum of eight keys can be learned to each WCM. Once a key is learned to a WCM, that key has acquired the Secret Key for that WCM and cannot be transferred to any other WCM 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 WCM memory.
PROGRAMMING KEY FAILED (POSSIBLE USED KEY FROM WRONG VEHICLE) - WCM is unable to program an ignition key transponder due to one of the following:
1. The ignition key transponder is ineffective.
2. The ignition key transponder is or has been already programmed to another vehicle.
8 KEYS ALREADY LEARNED, PROGRAMMING NOT DONE - The WCM 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 WCM memory.
