Programming The RF Hub And Key Fobs

WARNING: This page is about a different car, the 2021 Jeep Grand Cherokee L. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

An "Erase Programmed Key" procedure is provided within the wiTECH service tool. A Personal Identification Number (PIN) is required to erase original fobs. If programmed fobs are erased accidentally, then original programmed fobs can be reprogrammed to the SAME Vehicle Identification Number (VIN) ONLY. A pre-programmed fob cannot be reprogrammed to another VIN. A new blank fob obtained from Mopar® service can be added to a VIN only one time and will remain mated to the VIN even if the fob is erased from the VIN. It can, however, be reprogrammed.

NOTE:

If a Body Control Module (BCM) is also going to be replaced at this time, before proceeding. Refer to IMMOBILIZER MODULES REPLACEMENT .

NOTE:

The key fob must be held against the Keyless Ignition Node (KIN) during programming.

After the Radio Frequency (RF) Hub module has been replaced with new unit, connect the diagnostic scan tool to the Data Link Connector (DLC). Refer to CONNECTOR, DATA LINK (DLC), DESCRIPTION AND OPERATION .
Using the diagnostic scan tool, navigate to the Immobilizer Modules Replacement in the "Vehicle View" screen.
Use the diagnostic scan tool to select "Immobilizer Modules Replacement" and then perform the "Immobilizer Modules Replacement" routine.
NOTE:
Do not put a laptop or other wireless device (cell phone, audio device, etc.) on top of or near the center console (between the seats to the dash). The Low Frequency (LF) antenna is below the center console and these devices may interrupt programming. Verify the key fob that is being programmed is inside the vehicle away from nearby consumer electronics. Disconnect aftermarket cell phone chargers before attempting to program the key fob.
Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
