My remote has a small compartment on the back side where the battery resides. I have changed my battery on two occasions and it looks as if I will have to change it once again. I needed a jewelers screw driver in order to unscrew the tiny screws in the remote battery compartment. I was told originally by the dealership/stealership that I would need to purchase a new remote because my remote had no battery when mine stopped working... Simply turn your remote over and look near the bottom quarter of it, you should see a plastic strip which pops off exposing two small screws, underneath that panel is the battery. It looks like a watch battery. Might I suggest Radio Shack... Good Luck, and Happy motoring...
