Item pickup trigger sound help

[Xallikk]

Hey, sorry for posting so much, just running into a few problems that I can't figure out. I want to make it so when the player picks up a key, a sound is played, but besides using an area near the key to simulate that, I can't see a way to do that.

Also, along the same lines, is it possible to take control of player's camera after the key is picked up and turn them to a closet so a monster can come out kinda thing?
