A: I need to speak with the manager, please.

B: Yes, this is the manager. How may I help you this morning?

A: We are having problems getting into our apartment.

B: Is this the first time that you have tried this key since I gave it to you?

A: Yes, this is the first time that we have tried this key. 

B: Does the key go into the lock okay?

A: It fits in the lock just fine.

B: Let's try it one more time. Just try to gently slide the key in the deadbolt and turn it to the right.

A: It still doesn't work.

B: I will come up to help you right away. I'll bring another key to try.
