[ACS] Checking if player attempts to unlock door?

Hi,
I want to recreate the keycard functionality from duke 3d, in which the player pulls up the proper keycard when he unlocks the appropriate door. Would it be possible to check, regardless of the map, whether the player is attempting to unlock a key-locked door?
