Key of the Locksmith

Looking similar to an old fashioned key, this magical item is able to claim any lock as its own. If this key is used on a door, it changes the lock to only fit the new key, to only allow its owner (or duplicate keys) to use that door. This effect only happens once per day, so any lock not previously affected by the key, may not use the key as a skeleton key.
