New Padlock with Key, All Wood

This is a new rendition of a padlock. There's a key this time, so don't lose it. This one was designed as a challenge to make an unpickable lock. As is in most cases, the picker has never seen the key. The key would give away too many clues as to how to pick the lock.
I'll update this when I find out what broke first: the lock, or his resolve. :-)

Update: :-) His resolve! :-)
