It's amazing how many things take this size battery, I've got a whole box of them stashed in the cupboard

Who needs an instruction manual when this forum exists, super quick fix to replace the D4 battery, as a side has anyone managed to source replacement D4 fob "shell only", a previous owner wasn't so careful opening the fob and has broken the casing.
TIA.
EDIT, I just had a look online and the fob is available readily from the normal amazon, ebay outlets.
Roughly a tenner.

Replacing the outer casing is easy enough, buy the genuine part - you will need a soldering iron or something to melt the two plastic legs that the PCB sits on and keep the pcb secure - everything is simple enoughMust stop buying shiny toys....

Problem isn't replacing the battery, it's getting the battery out of its effing packaging without puncturing it or your fingers.

granny proof packaging, I measured the offending battery it still had 2.8vdc surprising it was producing a fault!
