The Yellow Door Lock (YDL) is an item from Baldi's Basics In Education & Learning. The protagonist can obtain this item when they visit a specific Faculty Room. There are no other locations in the game in which this lock can be obtained.
It is nothing else than a lock with silvery-tinted colors.
Its only use is to lock any yellow door in the school, preventing any character, including the player, from entering the door from either side. When the lock is applied to the door, Baldi will try to find another way to the player. The lock can only stay on the door for around 10 seconds, but for the player it is most useful when they're running away from Baldi in the later stages of the game unless Baldi knows a shortcut to the Player.
- The Yellow Door Lock might be similar to an Old English Padlock.
