My friend got locked out three times, and I got his door opened three times. The first time the locksmith stuffed some strings into the keyhole and magic happened - he unlocked the door like that. The second time the locksmith (different one) went through the peep whole and hooked the door open. The third time, the locksmith (another different one) had to change the lock to open it. Funny how different people do things in drastically different ways.
