Elevator Attacks

Fireman mode/service technician mode

Might be keyed-alike. Can also be picked.

Fireman mode overrides any access restrictions that have been programmed into the elevator. So you can use it to gain unauthorized access to restricted floors

Tailgating

Let’s say the top floor is restricted. You can keep calling elevators (going up) until you get one where a person is riding to that restricted floor. Then just keep going with thatperson. If you get empty elevators, then just send them down.
