What I'm talking about is way simpler than some of you presume. I
simply want electromagnets in the doorframe which hold to metal plates
in the door when on. No moving parts! The magnetic reed switch would
be used to swich the circuit off. don't need super high security, but
something a bit better than what I have now. Since they would be on
whenever I'm out, I would want very low current drain. I've found some
suitable units, but I would prefer to pay less.

Put the magnets in the frame and the plates on the door - lots of room and
no trouble with wiring or supply.

Don't drop a watch (or worse, your key on a steel ring) on the sill when
it's locked.
