Lock dilemmas

Saturday morning when I brought a friend of mine back home, we ended up standing in front of a very locked gate. The key managed to turn the turnable inside part of the lock as it is supposed to, but the catch that is supposed to move decided not to do so.

The end of the story was that nobody came and went at 3AM, the lock didn't open, and my friend ended up staying at my place for the night. On Sunday I brought him back on my way to the office. Another resident there had no problems with his key, so it could be a key related issue.
