I like the way the Model 30 implemented its keylock. Locking the key switch
will short out two terminals on the motherboard and disable the keyboard.
One of the wires going to the switch is captured by a metal piece and held
right next to a hole that is covered by a rubber foot. If you lose your key
you simply remove the foot, reach in with a small pair of wire clippers and
your back in business.
