key not unlocking door

[peepeeboynotreal]

Your script seems fine to me, the only possible things I think of that would stop it from unlocking are
A) You've made a typo in the level editor and the names aren't matched up exactly, or
B) You need to delete the cache file. Delete "<mapname>.map_cache" and it should be good

Edit: Also sorry but in the future you should probably post questions like this in the development support section

done both of those things and its still not working....
