Put your good key in the ignition and turn to "ON", do not start the engine. Make sure all the remotes you want to use are present because they have to be programmed at the same time.
- Close the door and insert key #2 into the driver's side lock. Lock the door.
-Within 5 seconds of locking the door, press unlock 2 times on the new remote, key #2.
-(if this is remote #3, press unlock 3 times. if this is remote #4, press unlock 4 times).
-If there's a chirp or beep do not press it again. This means that the car has recognized the new keyless entry remote.
- Repeat with other remote or unlock the car and turn off - done.
