Master Lock Magnum Heavy-Duty Stainless-Steel Discus Padlock with Keys, Keyed Alike Heavy Duty Storage Lock for Indoor or Outdoor Use, M40XKAD

I live by the ocean where everything is constantly bathed in salt. I use these locks on my outdoor sheds, and they last longer than any other locks I've tried. The little cover over the keyhole prevents corrosion, and even after several months they still lock and unlock easily. It's also convenient to have the same key for all three locks.

I got this for two different storage units. I really like that they use the same key. No lock can stop a determined thief but these do seem much better quality than the cheap ones the Storage office sells.

Worked great. Durable. Comes with keys to unlock. Would purchase again, as it did the job. Used to lock U-Haul traveling across country.

Bought this for my storage unit in a college town—very sturdy and feels super secure. I love that it comes with two keys so I can give one to my roommate. The only downside is that you have to leave the key in the lock to keep it unlocked, which can be a little inconvenient when you're moving things in and out.

I thought my storage unit was going to be outside, so I liked the idea of a key cover to protect against elements. It’s nice having a lock now that I can confidently use outside when the time comes. Nice quality, definitely better quality than the standard locks of this style.

I use this lock for my storage unit. It actually saves me money on the insurance because it's the specific type they require. Has a pad over the keyhole to prevent rain from getting in and resting it.

I have bought these before for our trailer, they are top notch and great quality. I feel better with these than regular padlocks. Will buy again if we need to!

Great lock for storage buildings!
