Well, one method would be making both the key and door dense, thus when the mob walks into it, call the Bump() proc to verify if it's a door/key. If it's a key, move it to the mob's inventory or if it's a door, check if the key is in the mob's contents, and if it is, open the door...


Procs needed to be looked up in this method:
Bump()
locate()
Move()

Here is an EXAMPLE... read, learn, ask questions ;) Like any eample, this may not be an efficient one but the point of examples is to convey the meaning, rather than the result...wellm most of the times anyways... I think...
item/keys
  icon='key.dmi'
  density=1//item is dense.. meaning people can't walk pass it... important for Bump() to work
  var/unlock//eh some var I made for keys to unlock

  key2
    name="Steel door key"
    unlock="steel" //lets say this unlocks only steel doors

Door
    var/locked//lets say to unlock this door, you need the same key as the locked one
    Steel
        icon='steel door.dmi'
        density=1
        dir=NORTH//Lets say that its blocking the way from continuing NORTHwards
        locked="steel"

mob/Bump(atom/O)//lets say if you did mob/M, you MUST do safetychecks to make sure it is a mob.. such as using ismob()
    if(istype(O,/item)) O.Move(src) //if it's an item, it'll go into the usr's contents
    else if(istype(O,/Door))
        var/Door/D=O//so we don't get any annoying errors (note that locked is only in /Door and unlock is only in item/key)
       if(D.locked)//if the door is "locked" (TRUE)
            for(var/item/keys/K in src)//checks usr's contents for any keys
                if(K.unlock==D.locked)//if the key unlocks this door
                    D.locked=null//door is unlocked
                    del(K)//item is deleted
                    break //stops the loop from continuing, as we already openned the door
        else src.Move(step(D,D.dir))//Moves the usr 1 step north from the unlocked door

These procs are especially helpful:

turf/Entered(A)
    ..()
    for(var/atom/O in src.contents)
        O.Trigger(A)

atom/proc/Trigger(atom/movable/A)
    return

atom/movable/Bump(atom/A)
    A.Bumped(src)
    return

atom/proc/Bumped(atom/movable/A)
    return


Then just have it so when you move over a key, it calls key.Trigger(), and when the key is triggered, it moves to the player's contents.

When unlocking a door, you can use door.Bumped(player), then just search for the proper key in their inventory. If they have it, then set the door to its unlocked state.
