Several buttons are not functioning but I can not get this darn thing open to
attempt a repair. Anyone know how to open it? TIA
As with any other remote control, if you take the battery cover off
and can't see any screws, then it's likely the two halves simpy click
together. Even if you know where the plastic lugs are, you may end up
sacrificing one or two when you do separate the two halves.
There's a section on remote controls in the group FAQ:
