Step 1: Enter Programming Mode
- Insert the original key into the ignition and turn it to the "On" position without starting the engine.
- On the vehicle's display, make sure the odometer is shown and the radio is turned off, as these may cause interference during programming.

- Toggle through the menu options using the trip odometer reset stem (located on the instrument panel) until you find "Press to Relearn Remote Key."
- Press and hold the trip odometer reset stem for approximately three seconds until the message, "Remote Key Learning Active," appears on the display.
Step 3: Program the New Key Fob
- Create a comfortable distance from the vehicle with the new key fob in hand.
- Press and hold both the "Lock" and "Unlock" buttons on the new key fob at the same time for about 15 seconds.
- You'll know the programming was successful when you hear the door locks cycle, locking and unlocking.
Step 4: Exit Programming Mode
- To complete the programming process, turn the ignition to the "Off" position and remove the key from the ignition.
- Test the new key fob by locking and unlocking the doors to ensure it operates correctly.
Troubleshooting
- If the key fob programming fails, repeat the steps. It's essential to ensure each step is followed precisely.
- Check the battery of the new key fob, as a low or dead battery can prevent successful programming.
