A padlock is configured to be locked and unlocked by a key and includes a lock body having an internal cavity with a locking mechanism and a keyway extending through the lock body into the internal cavity to provide access to the locking mechanism by the key. The locking mechanism is configured to be selectively moved over a range of positions when the key is received therein to lock and unlock the padlock. The keyway has an eccentric profile that permits the key to be removed from the locking mechanism in only a single position of the range of positions.
