Programming The SKREEM

WARNING: This page is about a different car, the 2006 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.

The SKIS Secret Key is an ID code that is unique to each SKREEM/WCM. This code is programmed and stored in the SKREEM/WCM, the PCM/ECM, and each ignition key transponder chip. When the PCM or SKREEM/WCM is replaced, it is necessary to program the Secret Key into the new module using a diagnostic scan tool. Follow the programming steps outlined in the diagnostic scan tool for PCM Replaced  or WCM Replaced  under Miscellaneous Functions  for the WCM/Wireless Control Module  menu item as appropriate.

NOTE: Be certain to enter the correct country code for the SKREEM/WCM. If the incorrect country code is programmed into the SKREEM, it cannot be changed and the SKREEM must be replaced.
NOTE: In addition, the SKREEM/WCM must be configured for certain optional equipment in the vehicle, including Tire Pressure Monitor (TPM) and Remote Keyless Entry (RKE). Follow the programming steps outlined in the diagnostic scan tool under MISCELLANEOUS FUNCTIONS for the WCM/WIRELESS CONTROL MODULE menu item as appropriate.
NOTE: A replacement SKREEM/WCM is supplied with TPM enabled by default; therefore, if the vehicle is not equipped with TPM, the ElectroMechanical Instrument Cluster (EMIC) will incorrectly learn that the vehicle has TPM after the replacement SKREEM is installed. The TPM indicator in the EMIC will illuminate to show a TPM fault condition after TPM has been disabled in the SKREEM. The EMIC must unlearn TPM to correct this false TPM indication. Follow the programming steps outlined in the diagnostic scan tool for CLEAR LEARNED FEATURES under MISCELLANEOUS FUNCTIONS for the INSTRUMENT CLUSTER menu item as appropriate.
NOTE: If the PCM/ECM and the SKREEM/WCM are replaced at the same time, all vehicle ignition keys will need to be replaced and new keys programmed into the new SKREEM/WCM.
NOTE: Programming the PCM/ECM or SKREEM 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 then enter the correct PIN. (Ensure all accessories are turned OFF. Also monitor the battery state and connect a battery charger if necessary).
