Programming Guide for 2020 Smart Keyless Entry Remote Fob

Important Notice: This vehicle supports onboard programming of remote fobs. A new remote fob can be added either using two recognized fobs or by following a timed procedure if no remotes are available. The vehicle can be programmed with up to eight remotes. Please follow the appropriate instructions based on your situation.

Programming with Two Recognized Remote Fobs: This method is used when two functioning remote fobs are available.

  • Step 1: Ensure the vehicle is completely off and that all doors are securely closed.
  • Step 2: Place both recognized remote fobs inside the front cupholder.
  • Step 3: Remove the key lock cylinder cap on the driver’s door handle to expose the mechanical key slot.
  • Step 4: Insert the mechanical key into the lock cylinder and turn it to the unlock position five times within 10 seconds. The Driver Information Center (DIC) will display READY FOR REMOTE #2, indicating that the system is ready for programming.
  • Step 5: Open the center console storage area between the front seats. Lift the storage tray to access the remote transmitter pocket, and place the new remote fob inside the pocket.
  • Step 6: Press the ENGINE START/STOP button once. The system will register the new remote, and the DIC will display a message indicating readiness for the next remote.
  • Step 7: Remove the newly programmed remote from the pocket and press either the Lock or Unlock button to verify that the remote is functioning correctly.
  • Step 8: Repeat Steps 5 through 7 for each additional remote fob you wish to program.
  • Step 9: After all remotes have been programmed, press and hold the ENGINE START/STOP button for 12 seconds to exit programming mode.
  • Step 10: Reinsert the mechanical key back into the remote fob.
  • Step 11: Reinstall the key lock cylinder cap on the driver’s door handle.

Programming Without Recognized Remote Fobs: If no recognized remotes are available, follow this 30-minute procedure to program new remotes. This feature may not be available in all regions.

  • Step 1: Ensure the vehicle is turned off and all doors are closed.
  • Step 2: Remove the key lock cylinder cap on the driver’s door handle to expose the lock.
  • Step 3: Insert the mechanical key into the lock and turn it to the unlock position five times within 10 seconds. The DIC will display REMOTE LEARN PENDING, PLEASE WAIT.
  • Step 4: Wait 10 minutes until the DIC displays PRESS ENGINE START BUTTON TO LEARN, then press the ENGINE START/STOP button.
  • Step 5: The DIC will return to REMOTE LEARN PENDING, PLEASE WAIT. Repeat Step 4 two more times, for a total of three cycles. After the third cycle, all previously programmed remotes will be erased, and the DIC will show READY FOR REMOTE #1.
  • Step 6: Open the center console storage area and lift the storage tray to access the transmitter pocket. Place the new remote fob inside the pocket.
  • Step 7: Press the ENGINE START/STOP button once. The system will recognize and program the new remote.
  • Step 8: Remove the remote from the pocket and press either the Lock or Unlock button to confirm it has been properly programmed.
  • Step 9: Repeat Steps 6 through 8 for each additional remote you wish to program.
  • Step 10: Once all remotes are programmed, press and hold the ENGINE START/STOP button for 12 seconds to exit programming mode.
  • Step 11: Reinsert the mechanical key back into the remote fob.
  • Step 12: Reinstall the key lock cylinder cap on the driver’s door handle.

Additional Considerations:

  • Maximum Supported Remotes: You can program up to eight remote fobs to the vehicle.
  • Timing Matters: Ensure all key turns and button presses are completed within the required time to avoid resetting the programming process.
  • Proof of Ownership: If no remotes are available, proof of ownership (e.g., title or registration) may be required by the service provider to authorize the programming.
