Central locking has stopped working on my ML270. Ive changed the battery in the fob, but is there a simple way of proving if its a fob or vehicle problem?

Thanks.
 
Does it work from the button on the dash?
Does it auto lock when you drive away?
 
The auto lock can be turned off, it was on my W163 when I got it, You can try it from the door key also, of all that works then it's probable the fob.
 
No auto lock, nor does it lock with key from door, or switch on console. Is there a common fuse or other known problem?
Thanks.
 
Central locking fuse is F42 in main fuse box also relays 20 23 and 24 control the central locking.
