A lot of trouble and expense though <g> Plus it would alert the
thief to the avenue of attack. He could sample and get lucky
with just thousands?
In a way, my scheme is a variation on yours except that almost
anything in the cabin could be a switch. It is just that fiddling
with most things does nothing whereas fiddling with one
particular thing in a very very particular way will do the trick.
(btw I did consider a number of switches and wiring them to have
only one combination that worked, but, of course, this is a just
a variation on keypad locks... <g>)
