I have a Philips Pronto universal remote control which has been stored away for a year or so. Unfortunately, as I discovered today, the batteries were left in place (I can tell by the weight). The slide-off battery cover is now completely unslideable and I suspect that one or more of the batteries has leaked, sealing the cover tightly shut.
If I'm right then the unit is probably a write off anyway but, just in case, is there anything which might persuade the cover to become moveable again? Mild heat? Cold? A quick poke with an angle grinder?
Many thanks.
