Keys to unlock copper door

Just like an iron door can be opened with redstone signal, copper door should also have a unique way to open it. The lock on the copper door texture give me an idea, which is to use a key to unlock the copper door

We know that the trial chamber will be separate into multiple rooms with copper doors. If the copper doors requires keys to unlock and open them, and the keys are hidden in potteries, then the players will be forced to search carefully in the trial chamber structure in order to get the keys, otherwise the player will continue under the buff of mining fatigue, unable to get in new chambers

The player can set the ownership to the copper door with the key by right-clicking on the copper door. Then the copper door will only unlock by this key. Hold the key and press shift + right click on the copper door will clear the ownership

The key will be crafted with gold nuggets and named in the anvil. The copper doors of each chamber will be locked with different keys with different names, so that players wont be able to open the doors only with one key

The unlocked copper door can be opened by hands and redstone signal, but it wont open by hands nor redstone when its locked

Unlike the named keys, the unnamed key will be able open every copper doors that set ownerships with the unamed keys, so players will need to named their keys then set the ownerships to the cooper doors in server

Keys can be copied in the smithing table, the copied keys will help when player lost the original key
