Find the key in the inventory (read back on how to find an item in the inventory), delete it, and let them in.

Try this:
turf/keydoor
  var/keycolor

  Enter(M)
    for(var/obj/key in M)
      if(key.keycolor==src.keycolor) return ..()
    return 0

  Entered(M)
    for(var/obj/key in M)
      if(key.keycolor==src.keycolor)
        del(key)
        break
    // replace the door with a blank turf
    var/turf/keydoor/door=src
    src=new /turf/floor(src)
    M.loc=src
    del(door)
    src.Entered(M)

obj/key
  var/keycolor

This uses keys of various colors, so you could have a red door with a red key, etc. It's actually easier to check for a specific key, but this way is more common to lots of games.

The above code is untested; I've never messed with modifying turfs at runtime before, so you might want to try it and tweak it as necessary.

Enter(M)
for(var/obj/key in M)
if(key.keycolor==src.keycolor) return ..()

I got a question, when your defining the mob/M and using it as Enter (M), where are you defining this?
Is it a global path?
or something like mob/M, obj/O, turf/T, area/A???

He didn't define it as mob, but it was a quick snippet to demonstrate the concept. You would probably want to make sure it's a mob, but since the only other thing that could ever trigger Enter() is an obj it wouldn't be much of a problem. Unless of course some clever adventurer stuffs the key in a bag and throws the bag through the doorway to open it from a distance. ;)

No, these aren't global defaults, but they have become an unofficial tradition in BYOND snippets. :)
