I think the key lock is prevent the aircraft from walking away without its
owner.
Turning on the radio with the keyless master buss will not steal the aircraft.
Interestingly, on topic, the WWII warbirds I have been in did not have keyed
switches
at all originally. I guess an armed guard was supposed to served the security
purpose. From what I have heard more modern warbirds (F16, A10, UH-1Y,
Cobra, etc.) maintain this tradition. Maybe Bud can expound on this, round the
campfire this week at KOSH.
