If you want a real key challenge, try those used by mid-90s IBM AS/400s.
They were electronic; a lozenge-shaped slab of plastic with a bunch of
contacts concealed in one end, and a chip of some kind inside (I never
dared hack one apart!)
IIRC, from the time I tried to obtain a spare, they weren't made by IBM;
the system was subcontracted out to a Native American owned company on a
reservation somewhere.
(The key in question was used to lock and unlock the front panel, select
IPL modes etc)

Is all the keyed stuff just power on type switches
or do we have real padlocked type stuff?
