Programming Guide for 2023 Smart Keyless Entry Remote Fob

Important Notice: This vehicle supports onboard programming for smart key remote fobs. A new fob can be added using two recognized fobs or by following a timed procedure if no remotes are available. Each vehicle can support up to eight remote fobs. Follow the instructions below based on your situation.

Programming with Two Recognized Remote Fobs: Use this method if you have two working remote fobs.

  • Step 1: Ensure that the vehicle is off and 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 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 to program.
  • Step 5: Open the center console storage area between the front seats. Lift the storage tray to access the transmitter pocket, then place the new remote inside.
  • Step 6: Press the ENGINE START/STOP button once. The vehicle will recognize and register the new remote, and the DIC will show that it is ready to program the next remote.
  • Step 7: Remove the newly programmed remote from the pocket and press the Lock or Unlock button to confirm the remote is working properly.
  • Step 8: Repeat Steps 5 through 7 for each additional remote fob you wish to program.
  • Step 9: Once all remotes have been programmed, press and hold the ENGINE START/STOP button for 12 seconds to exit programming mode.
  • Step 10: Return 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 remotes are available, follow this timed procedure to program new remotes. This process takes approximately 30 minutes and may not be available in all regions.

  • Step 1: Ensure that the vehicle is off and all doors are securely closed.
  • Step 2: Remove the key lock cylinder cap on the driver’s door handle to expose the mechanical key.
  • 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 10-minute 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, lift the storage tray, and place the first new remote inside the transmitter pocket.
  • Step 7: Press the ENGINE START/STOP button once. The vehicle 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 the remote is working.
  • Step 9: Repeat Steps 6 through 8 for any additional remote fobs 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: Return the mechanical key to its original position inside the remote fob.
  • Step 12: Reinstall the key lock cylinder cap on the driver’s door handle.

Additional Considerations:

  • Maximum Supported Remotes: This vehicle can support up to eight remote fobs.
  • Timing is Critical: Ensure that all actions involving key turns, button presses, and other steps are completed within the allotted time to avoid resetting the process.
  • Proof of Ownership: If no remotes are available and professional assistance is needed, proof of ownership (e.g., title, registration) may be required to proceed with programming.
