My focus has no central locking and the key fob also don't work ?

Fuses are fine.

 

At the rear of the glove box fusebox there is a fuse for the central locking f63. It's a fiddler fecker to get to but possible. I think the panel is held in with 2 10mm bolts.

If the fuse is ok then the micro switch inside the central locking module in the drivers door will be the culprit. Moisture and water make their way past the seal and drip onto the module causing it to short.

If you want any more info on it just google; focus central locking finally a solution!.
