Actually, after consideration, I need just such a system. Keypads would

Easy enough to do with one of the telephone door opening devices that
just move a plate back on a solenoid from what is otherwise a normal
front door lock keyed from both sides.

I also use a pair of electro magnets to hold a sliding gate closed but
manually operate able in the event of a power failure.
