scripting key and door

i want to script a key and door, where if the user is wearing the keyas an attachment to like a hud or something, and when he or she clicks on the door, and then the key whispers the "password" and the door checks the "password" and if its correct, it opens up.
--edit i figured it out

the simplest way I know to achieve this (for those that didn't figure it out) is to have the key listen for the door. when the door is touched it chats a message including the user id of the person that touched it, the key hears this, and if it matches the key owners id the key chat's back a message to open... the door hears this and opens.

Even though I saw the edit that you've said you got it, I'm providing this... Probably has some idiotic scripting but it works, gave it a good test run.
(I believe quoting gives out the original indentation.)

DOOR: (The included Open and Close functions use my favorite method of HollowDoor.)

If anyone would like, I made a basic system for this.
The included door open/close functions are for a hollow/full door, my favorite type.
Probably has scripting idiocies, but it works.
EDIT: Probably doesn't belong here in hindsight but hey maybe the OP will gain something fro it. XD
