One serious drawback of the electronic lock is powering it, but as
I've been writing this, it's occurred to me that one could mount a
power jack alongside the combination buttons. ;-)

Seems to me last time I looked at an eletronic combination lock safe
it was battery powered, and you could change the battery without
opening the safe.

Some of the security safes at work use a "wind up" lock. It has a magneto
in it, and you spin it several times to power up the lock.

the only catch with those things is eventually everybody loses track of
how many codes/users were set for it.
