How to make Iron maiden slam doors shut.

[2pikachuno]

So I'm working on a custom story and for the gameplay the player needs to go into an iron maiden so he can hide from the monster. But I want to program it so that when the player gets inside the iron maiden it will slam the doors shut on the player so the iron maiden is definitely closed. Any ideas how this can be achieved with a script. I have it set up so far that when the player enters the iron maiden a collision script is set to run but I just can't get the doors slam shut. Any advice or ideas?
