Locks and lockpicks

[yottabyte]

I know the discussion has been going on a lot about protected chests ever since the start of Kiwike 2.0. I know thieves would hate it and peaceful players would love it.
Some of you may remember nfmous idea about picking locks but nothing really ever happened on that front. So I've been thinking about locks recenly and I believe I have a pretty good idea for it.

Locks
You can somehow buy/make a lock for a chest. I haven't really been thinking too much about this yet but I'm sure we can come up with something. A lock would be pretty expensive to buy/make.

Locks can then be placed on a chest and the chest will be protected

Protection
A chest with a lock on it will be protected from placing chests next to it, tnt, destroying and opening. Only the owner of a chest can open it.

The chest will be fully protected when the owner is offline. After two weeks of inactivity the chest will go semi-protected. Same thing when the user is online.

A fully protected chest can't be opened or lock-picked in any way. It's just there
When the chest is semi-protected it can be lock-picked.

Picking locks
A thief can lock-pick a semi-protected chest using a golden hoe. To lock-pick a chest you stand next to it and right click it with the hoe. Your hoe's durability bar will go down (up to 100 first if it's been used) slowly. When the durability is at zero the lock-pick will be destroyed and you can open the chest. If you move or disconnect when lock-picking the process will be stopped and the durability will go back to what it was before.

Tell me what you think about all this. Anything you would like to point out and/or change?
