High Security Padlock Single - Military Grade Ideal for Storage Sheds, Toolboxes, Worksite, Gym Locker Lock, Portable Door Lock, Bolt Cutter Proof, Steel Alloy Design

I'm on my second purchase because the storage unit folks cut my lock off by mistake -- and they called me as soon as they realized it. I asked how it went and the guy who cut it off said "yeah, I wrecked the bolt cutters." When I showed them THIS one, the guy who cut it off took one look at the shackle cover and said "if you had that on, I never could've gotten in." I told him the only reason I didn't have it on was because I couldn't close the lock with it on, the door mechanism was just a bit too wide.

I BOUGHT THESE LOCKS BECAUSE SOMEONE WAS STEALING MY STUFF AT METRO STORAGE, THE LOCKS DID NOT FIT, HOWEVER, I STILL HAVE THESE LOCKS IN MY TRUNK.

I saw the reviews and thought 'why are people complaining about the lock being difficult?'Well, they're not kidding. It's easy to open when you have the key, but I consistently had issues trying to get it re-locked with the shackle cover on.Here's what I found that seemed reliable for me:First, look at the lock body as one hole goes deeper than the other. Make sure you insert the long side into the deeper hole. Turn the key however you need to shackle to insert. Turn the shackle so it's 180° from the lock body, then find the position where you can get the key to spin in the other direction. spin the shackle closed and insert it, and you should be able to remove the key.

This is the worst lock I have ever purchased it is supposed to be extra fancy this thing took me half an hour to try to unlock it then trying to relock it I couldn't

A few months back I was at my Globo-Gyms in one of the shadier areas of town, and I got a notice from my bank that someone had tried to use my debit card at a gas station. I finished up my set and went and saw that my flimsy combo lock had been busted and my bag stolen-- including my wallet. I'm still trying to replace my RealId.I did some research and found this lock from Commando Lock.It has mixed reviews, but I feel like most of the negatives can be mitigated.Despite being reasonably compact, this lock is heavy, like you could put it in a sock and use it as a deadly weapon. The shackle guard makes it incredibly hard to cut, and it also blocks access to the vulnerable part of the lock where the shackle enters the body. While you can technically leave the shackle guard off, I don't recommend it, as it greatly decreases a lot of the security of the lock when you do.The key part is also very secure-- but it's where the biggest caveat of this lock comes in. It takes some practice to use, because you have to turn the key twice to get the lock open and detach the shackle from the lock. I recommend, as soon as you get this lock, play around with it, and practice unlocking it. There are videos on YouTube discussing A. How thief resistant this lock is B. how to use it. It has a learning curve, but once you get it, you can open and close it pretty quickly. You don't want to use it without getting some practice in, especially if you're in a hurry to get it open.Overall, I really love this lock. I feel like I can leave my expensive laptop, wallet, and even passport in a locker for a 90-minute-long workout session without having to worry about it getting broken into-- I think a thief would have to break the actual physical locker before they're going to get past the lock. Your average gym locker thief isn't looking to spend 20 minutes getting into a locker, they're going to go to your neighbor's locker that has a cheap luggage combo lock before they go for yours.

Difficult to use, yes. Definitely takes some practice and won’t fit on all storage units because of the shackle guard but that’s the idea. Tough to mess with so it deters. No way anybody is breaking this off my storage unit, it would honestly be easier to just cut the door apart. Heavy duty and has lasted over a year in the Seattle rain with no issues. Will be buying another one for my trailer once I pull the crap out of my storage unit.

This lock is complicated. And it won’t take large chain as far as I can tell and have tried. I can’t use it for what I wanted it for, but I will keep it. What I tell you to buy it, No.

I've been using these locks for a bit now and they have performed well. Some users have reported difficulties with opening and even broken keys. It is true that these locks don't open as easily as a standard padlock but that's kind of the point. Isn't it?To open you turn the key clockwise about a quarter turn or so. That releases the shackle. Then you turn the lock around 180 degrees and turn the key back to the starting position and about a quarter turn anti clockwise. At this point the lock should come free of the shackle completely. To relock it simply do the steps in reverse.If you want the lock to function like a regular padlock simply remove the guard from the shackle and use as you normally would.Pros:A hard steel guard covers most of the shackle making cutting the lock off much more difficult.The complex unlocking sequence, while only somewhat cumbersome with the key, is a nightmare for picking (I've tried it).Cons:The lock has a learning curve but honestly not more than a few minutes of practice. Once you get it it's a piece of cake 🎂.The lock is probably a higher carbon steel. while this is good for cutting resistance it does make it more prone to rusting and if used outdoors will need periodic cleaning and maintenance. (I flush the lock with carburetor cleaner and swap with a cotton swab, then give it a generous lubrication with WD-40 or some equivalent)
