I have a 2005 S-Type.t oth remotes have stopped working. First one stopped so i switched the the spare and now after a few weeks it no longer works. Please tell me there is a way to replace the key fob battery cheaply!

I poped the key fob apart and sadly did not see the expected watch battery.

 

It's in the handbook

 

You must remove the circuit board to get to the battery. One small Phillips screw holds the circuit board in place. Remove the screw, lift up the circuit board, and you'll see the battery....

 

Thanks Jon, that did the trick. I now see a great post with pictures of the process. Good stuff.
