Keyless Entry Module: Service and Repair

MODULE-SENTRY KEY REMOTE ENTRY

WARNING: TO AVOID PERSONAL INJURY OR DEATH, ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE SUPPLEMENTAL RESTRAINT SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, AIRBAG, OCCUPANT CLASSIFICATION SYSTEM, SEAT BELT TENSIONER, IMPACT SENSOR, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING FURTHER DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE SUPPLEMENTAL RESTRAINT SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT.

REMOVAL




1. Disconnect and isolate the battery negative cable

NOTE: The Sentry Key REmote Entry Module (SKREEM) can be removed from the ignition lock housing without disconnecting the Brake Transmission Shift Interlock (BTSI) cable.

2. Lower the ignition key cylinder, lock housing (2) and switch (3) from the instrument panel as an assembly far enough to access the SKREEM mounting bracket.
3. Remove the screw (4) that secures the SKREEM mounting bracket to the ignition lock housing.
4. Disengage the SKREEM antenna ring (1) from around the ignition lock housing and remove the SKREEM.

INSTALLATION




1. Position the Sentry Key REmote Entry Module (SKREEM) onto the ignition lock housing (2) with the SKREEM antenna ring (1) oriented around the lock cylinder.
2. Install and tighten the screw (4) that secures the SKREEM mounting bracket to the housing. Tighten the screw to 2 N.m (20 in. lbs.).
3. Reinstall the ignition key cylinder, lock housing and switch (3) into the instrument panel as an assembly.
4. Reconnect the battery negative cable.

NOTE:
- On vehicles equipped with the optional Sentry Key Immobilizer System (SKIS), when the SKREEM is replaced with a new unit, a diagnostic scan tool MUST be used to initialize the new SKREEM and to program at least two Sentry Key transponders before the vehicle can be operated.
- On vehicles equipped with a premium Tire Pressure Monitoring (TPM) system, when the SKREEM or the spare tire pressure sensor is replaced with a new unit, a diagnostic scan tool MUST be used to run a routine that allows the SKREEM to be programmed with the ID number and location of the spare tire pressure sensor mounted in the wheel of the spare tire. Follow the programming steps outlined in the diagnostic scan tool for Learn Spare Tire Sensor ID under Miscellaneous Functions for the WCM/Wireless Control Module menu item as appropriate. In addition, if the SKREEM is replaced, the spare tire must be dismounted from its wheel to access and note the ID number on the spare tire pressure sensor so that the ID code for that sensor can be programmed into the new SKREEM.
