Hmm fob is annoying. Lock button works but unlock and boot release don't. Can't really get a look at the PCB either it seems to be moulded in there.

Sounds silly but try a new battery in the Keyfob....unless you already have done.

I'll get some batteries today I've got a bunch of stuff that take those batteries that have all run out.

I don't think it's that though. The lock button works just fine so surely there must be enough charge in it.
