Use the New Key Fob: Use the new key fob to manually lock the driver’s side door.
Hold in Lock Position: Hold the key in the lock position for 10 seconds. The red LED alarm light next to the lock button should be blinking. If it does not blink, the alarm does not recognize the door is closed, and it will not go into program mode.

Press a Button: Within 2 seconds, press any button on the new key fob.
Press Again: Immediately press the same button again.
Check for Confirmation: The turn signal lights should flash, indicating that the remote is now recognized by the car’s system.

Test the New Key Fob: Test all the buttons on the new key fob to ensure they are working correctly.

3.3. Programming the Transponder Chip
