W203 key resync.

[Tim203]

Changed batteries and tried the resync ( turn to 2nd click, press lock and unlock 5 times etc but still doesn't make the central locking work.
Has anyone got any ideas please.

When ever I changed the batteries in my W203 fob never had to resync anything

Thanks guys, must have buggered it up when I got lobbed in a hot tub the other week then

Do you have two fobs - and if so are both having issues?

I believe the central locking fuse is no 8 in the boot fusebox.

Chefin's key works fine, mine starts the car but won't do the locking. I had my phone fixing guy clean it and replace the batteries as well. Thanks for your help.
