Locks are little blocks made to lock Gates. You place them with left clicks, and they have an area of 16 blocks. They can be opened with keys, weapons/tools and bombs. The locks and keys are numbered, on the name at keys, and on top of them at locks (the same way as name tags), so you can only open a lock with specific key. If a friend gives you a key, they would have two numbers, the normal number, and a number that marks who gave it. Locks from others also have the second number.

They could be made of six ingots, the type depends how strong you want to make it. Place four in a square at the top-right, one in the bottom-middle and last one on bottom-left. It would make a lock and a key. They would have the same shape as Utumno keys.

You can make copy of a key by putting a key and two ingots (the same as the key). Those would say Copy of key ~. You can only copy keys if you made the original one (but you can copy a copy). You can also craft two keys together. NPC's can open any Gates, except locked ones. You can give NPC's keys at the same place you give them armour, as there would be 15 places more, with a shadowing picture of a key.
