If pressing the buttons on the remote key does not open or close the vehicle, the battery may be flat and needs replacing; use a very small flathead screwdriver to pry along the slot at the base of the shell that houses the buttons: you need to unclip and remove the portion of the shell with the buttons to access the battery compartment; then remove the old battery and insert the new one, ensuring the correct polarity, and close the key by snapping the shell back into place.
