A little lock with a key symbol on it which is yellow when you buy it or the lock is set to allow everyone to build, green when you own the placed small lock and red when you do not have the access.This lock costs 50 gems in the store and is the smallest of all the locks. Using the wrench on this lock after it has been placed in a world allows the owner to alter which people can build within the locked area and what shape/size the area is as long as the intended area is 10 blocks or less. This is most often the first lock bought by a player to claim a world. It is the cheapest lock, and not surprisingly, the worst.
