Brady SafeKey Lockout Padlock - Heavy Duty Aluminum Safety Lock with 1.5" Steel Shackle, Keyed Different (6-Pack) - Ideal for Industrial Equipment, Electrical Panels & Workplace Safety Lockout Tagout Procedures

I never write reviews however I feel like I should on this lock since there are not many posted. Right off the bat, I love this lock. However, I almost returned it right when I opened the box. The reason was that the key was so difficult to put into the lock I had to force the key in by pressing the key on my desk and pushing as hard as possible into the lock. I decided to put one tiny drop of 3-in-1 oil into the keyhole and the lock instantly freed up and works amazingly. Hopefully, my lock was just a factory defect that they didn't put any assembly lube in. The only downside to the oil I used is I had to wipe the key off each time I used it for the first 15 times because otherwise, the key would leave greasy marks on stuff.Final criticism and this will probably be the most important fact for most buyers. This lock comes with only one key, I am unaware of any locksmith that carries the blanks for this key to make you a second one. I really wish that would sell a model of this same lock with 2 or 3 keys, even if it's $10 more expensive I would pay it.
