Currently, emags can't open firelocks: you get the message "access denied", which doesn't make sense.
Also, remember that time when you were a nuke op with a bag full of weapons and had no space for tools? Because no one carries a crowbar as a nuke op. Then the rest of your team bombed the whole station, firelocks were on high alert, and you found yourself stuck there forever with no way out. You kept trying to use your emag and thinking to yourself "WHY!".
Also, this is my first PR.
