level doors

[megsb927]

ok so I start the game in my first map, the door to the second map says locked when you try to open it, then I get the key and use it on the door. I can hear the unlock sound and the key dissapears but when i click on the door it still says locked. In the entity tab the door is checked as locked and the map it goes to is my second map and player start area 1 for the next map but it won't let me go to it.
