Key Fob Programming

The Radio Frequency Hub (RFH) may be programmed to recognize up to a total of eight FOBIKs. When replacing or adding a FOBIK, the integrated key must be cut to match the door lock cylinder in the vehicle for which it will be used. Once an additional or new key has been cut, the RFH must be programmed to recognize it is a valid FOBIK  . When programming a FOBIK it will be necessary to have a vehicle Sentry Key PIN. Follow the instructions on the scan tool screen.

This procedure will require you to log into DealerCONNECT and enter a PIN when requested. The PIN is temporary and will be active for 12 hours. After 12 hours, a new PIN will need to be obtained from DealerCONNECT. 

NOTE:

Only ONE FOBIK can be programmed at a time.

NOTE:

Do not put a Laptop or other wireless device (cell phone, cell phone, audio device, and others) 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. Make sure that 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.

NOTE:

Before programming any FOBIK (new or used), the FOBIK battery should be tested using the RFI tool.

The FOBIK should be tested by pressing ALL buttons, the RFI tool should respond to every button press by lighting up and beeping.

  1. Turn the Ignition on.
  2. With the scan tool select RFH
  3. Go to "View", select "Data" tab. Select "Number of Key/Fob programmed" to ensure programmed FOBIKs are fewer than eight (8).
  4. Turn the ignition off. The ignition must be left off throughout this procedure.
  5. With the scan tool select, "Misc. Functions", and then "Program Ignition FOBIKs".
NOTE:

Premium System (Push-Button Start) - When programming a FOBIK hold it near or on the center console between the seats. When you instructed to "Press the Unlock Button" (if Unlock is not present, press the Panic button), it is important that the button is not held down. Press the button one time only. DO NOT PRESS BUTTONS WHILE PROGRAMMING IS IN PROGRESS.

NOTE:

Baseline System (Rotary - FOBIK Insertion) - When programming a FOBIK, place the new, un-programmed FOBIK into the ignition. Leave the FOBIK in the LOCK position. DO NOT PRESS BUTTONS WHILE PROGRAMMING IS IN PROGRESS.

  1. Have Sentry Key PIN available as this will be required to be entered into the scan tool.
  2. Press "Continue" and follow the instructions on the screen. Programming can take as long as 20 seconds. ONCE PROGRAMMING HAS STARTED DO NOT PRESS BUTTONS ON FOBIK.
  3. When the programming is completed the screen will display "Programming of Ignition FOBIK successful, continue to program another or close", or "Unable to Program FOBIK".
    1. If the programming is successful, select "Continue" to program another FOBIK or "Close" if no more FOBIKs are to be programmed.
    2. If the programming is unsuccessful, another programming attempt can be performed.
NOTE:

A second attempt at programming will automatically return a programming failure, as this attempt will try to reset the FOBIK to factory defaults. A third programming attempt must be performed before a determination that the FOBIK cannot be programmed can be made.

  1. Final programming step requires pressing any button on the FOBIK to synchronize the rolling count. A single button press is required, and there should be no response from the vehicle.
  2. Verify successful programming. On Baseline vehicles (Rotary - FOBIK Insertion) remove the FOBIK from the ignition. On all vehicles press the various buttons to verify operation. Verify the vehicle will start (NOTE: On Premium Vehicles (Push-Button Start), ensure no other programmed FOBIKs are inside vehicle when attempting to start).
  3. Using the scan tool, select RFH, select "View", select "Data" tab to verify "Number of Key/Fob Programmed" equals the new programmed FOBIK count.
