Fortunately, you can try programming your key fob yourself with a few simple procedures.

3. Press “Open” Button (First Remote): Take the key fob you want to program first and press the “Open” button once. You should hear the alarm horn beep briefly to confirm the signal reception. This assigns a memory address to the first remote.
4. Wait and Press “Open” Again: Wait for six seconds after pressing the button, and then press the “Open” button again.
5. Doors Unlock: The doors should unlock, indicating that the first remote unit is now successfully programmed.
6. Mechanically Lock Again: Use the second key to manually lock the driver’s door again.
7. Press “Open” Button Twice (Second Remote): For the second key fob, press the “Open” button twice within one-second intervals. This assigns a memory address to the second remote.
8. Wait and Press “Open” Again: Wait six seconds and then press the “Open” button again.
9. Doors Unlock (Second Remote Programmed): The doors will unlock, confirming that the second transmitter is programmed.
10. Repeat for Additional Remotes: If you have more key fobs to program (up to four total), repeat step 7 and 8 for each additional remote, incrementing the number of “Open” button presses by one for each subsequent key fob.
11. Switch Ignition OFF: Turn the ignition key to the “OFF” position and remove the key.
12. Test Key Fobs: Check each programmed key fob to ensure it is functioning correctly by locking and unlocking the doors remotely.

Method 2: Alternative Key Fob Programming Procedure

This is a slightly different approach that also utilizes the ignition and door locking mechanism:

1. Ignition ON with First Key: Insert one key into the ignition and turn the ignition to the “ON” position. Leave the ignition on throughout this procedure.
2. Lock Driver Door with Second Key: Get out of the car, close the driver’s door, and use the second key to manually lock the driver’s door. The ignition must remain ON during this step.
3. Press “UNLOCK” Button (First Remote): Take the key fob you are programming and press the “UNLOCK” button once. The alarm may beep, but the door will remain locked.
4. Unlock and Lock Door with Key: Using the physical key in the driver’s door, unlock and then relock the door again.
5. Test Remote: Press the “UNLOCK” button on the key fob again. The door should now unlock if the programming was successful.
6. Open Door and Cycle Ignition: Open the driver’s door, turn the ignition off and then back on again using the first key. This completes the programming sequence.
