Help with Locking door Script

Hello, I have a unique type of door on a boat which consists of three pieces that slide together to close. There is a rotation script that allows the doors to do this but no locking script. I've noticed further down on these forums that a few locking scripts have been posted here so I've tried to insert those scripts into each piece of my rotating doors, but it doesn't seem to work--even after I've added the av key. When I say "lock" or "unlock" I hear the word "confirmed" but the door never locks for anyone. Also, the other person whose av key I've inserted doesn't even hear the voice confirmation. This locking script does work for the single piece doors I have on my house.

I feel like I'm going about this in the wrong way and since I'm very, very new to scripting I thought I would ask for help here. Even if someone knows of an inexpensive ready-made solution in world I would appreciate it very much!
