Exit Door, Regular Doors (Gates), Trap Doors

No puzzle game would be complete without arbitrarily locked doors! These doors have to be activated with a button OR unlocked with a key if they have a lock and chain on them. Mechanically they are all almost identical, both Chucky AND Dexter have to leave through the exit door to complete a level. Trap doors are on the floor and can only be accessed by Dexter.
