Trial key needed for opening locked copper doors and trapdoors

The community will undoubtedly love it if they add locks to copper doors and trapdoors!!!
So the details:

• The key can be used to lock and unlock copper doors and trapdoors. The copper door or trapdoor is unlocked by default and requires a trial key for locking.
• The trial key can be renamed to change the password. Anyone with the trial key with the same name can unlock copper doors and trapdoors.
• If a locked copper door or trapdoor is destroyed/broken it will emit redstone signals in all directions.

Moreover, if they add copper chests or lockable chests:
It's also lockable and unlocked by default.
If it is breaked then:
        a) A random percentage of items inside it will disappear.
       OR
        b)An item is dropped as a last chance to obtain existing items using the trial key of a specific name.
It also emits a redstone signal upon breaking

Note: Mojang feel free to change these ideas. But of course, the community will love it. :D
