These kinds of locks are a locksmith’s dream. They’re just one of the least difficult locks to open. A few padlocks may be re-keyable, while other are not. In addition, some padlocks retain their key once the lock is unlocked so that the key cannot be removed. Some other padlocks are bolt-cutter resistant by having a surrounded shackle.
