[No Author]

i got into game and picked key up and it says picked up
and i tryed using it on the door that it supposed to unlock and it says no object to use item on??

Did you put your custom key name in the .lang file ?
Also for the "no object to use item on", when you double click the key in your inventory, you have to wait at least 1 second to make it work.
