[Solved] Open Gates with key .

[BLazeKraze]

Ehem... Ahmm, I have a little question because I'm confused ..
How do I open a gates with key . For example the unit has a key and the unit enters to the region and the gates will open.
And without key, the gate will not open .
How I can do that ?
Can you show some triggers ???

EDIT :
Oh no, I already solved, sorry for post
