Rendezvous - S2-E10
Corrected entry: When Mahoney is locked in the cage, you can see that both sides of the cage door have key locks, but when William Kim comes to rescue him, William magically has The Key. (00:13:20 - 00:33:40)

Correction: While locked in the cage, Alex called Kellerman but instead Bill Kim was sent to pick him up. So he not only knew where he was locked up at, but had plenty of time to get a key.
