I replaced battery on mine, it literally takes seconds. Takes the key out, put it in backwards, and use a little tech screw driver to pop the battery out.

I have more of a problem removing the decorative cover I put over the original FOB than changing the battery. After you do it once, it should take less than a minute.

What's the difficult part? I sometimes use a flashlight to see the tab where you use the tip of the key to press against to open the back. Once you find the right spot, it pops right up. I just use an Xacto blade to pop the battery out, I suppose anything with a sharp tip will work.
