If you need to replace the remote key battery because it can no longer open and unlock the doors, follow the instructions below. First, get a small Phillips screwdriver to remove the screw located at the back of the key. Then, remove the back cover, and underneath, you will find the transponder and the battery inside it. Use a sharp object to remove the old battery and replace it with the new one, being careful to maintain the polarity orientation.

Then, reposition the transponder on the key and reinsert the cover screw.
