Hi it is me!

If any know me now just to let you all know, things are starting to look up.

But one thing has just stopped working.

My key dose not open the car door remotely, it did work one week ago, but I put it with the mechanic and when I got it back it was not working.

I have another key and that is working ok.

But I do not know how to change the battery on my old key.

Any one knows any thing.
