I don’t see being unable to unlock the door without the switch and leave or am I missing something?

It is not stated. All is implied. We are told he could lock the door from his desk, with a switch.

We do not know if it could be unlocked without the switch, but that would be very tricky. It would require a third mechanism.

I would love to see the contract for the lock installation!
