For what it's worth - when I worked in the Cooler
department here
at Coca-Cola we used a automotive dent puller (which is a kind of
slide hammer) to pull locks in vending machines. We had the hardest
type to break into because we used Abloy locks.
I hope this is never necessary for a classic computer! For the DEC
and DG machines that I'm familiar with and which used a real lock
cylinder, all you have to do is remove the front panel, loosen a nut,
and pull the cylinder. It does pay to look carefully before doing this,
as when you put in the new cylinder you want the cam in the correct
position to activate the microswitches.
If you aren't patient enough to put in a new cylinder, you can use
small objects (my favorites were guitar picks) to close the
appropriate microswitches you need to operate the machine.
