Already do - because my volume buttons are knackered!

Now there's a really simple DIY job right there.

Carefully "fiddling" your way around the seam of the remote you'll
eventually workout where the internal clips hide (4 most likely)and
which direction to ease them with a fine bladed tool to split the case.

Once you have the remote in half(s) the conductive "rubber" key-pad can
be lifted off as a complete sheet and you'll spot the dirty contacts on
the PCB.
Give them all a wipe with your preferred cleaning solvent (Think I used
nail varnish remover last time) and clean the contact side of the rubber
buttons while you're at it.

Reassemble and your remote is good as new once more.

I'll try that - ta.

I used to think it was the conductive layer wearing off that caused
failure, not dirt.
