Master LockHeavy Duty Disc Padlock [Combination] [Stainless Steel] [Outdoor] M40EURDNUM - Best Used for Storage Units, Sheds, Garages, Trailers and More

I needed some good locks to lock down my father’s gates to his fence as we go through probate to settle things. These locks are great to protect from gaining access to the gates. I had some of the thinner metal locks on the gate and some cut through that lock. Well, they will not cut through these locks. The are really heavy and great quality. I did find the instructions a little hard as mines got torn off when I opened the packaging and it took me an hour to try and understand where are they located and I finally found the passcode and stuff. It was torn off with the packaging so I never found it where it said it’s was. Need to do a better job of placing the passcodes where they will not get torn with the packaging and then you can not find it as I thought it did not come with a passcode. Other than that, excellent heavy locks to secure a gate or anything more securely. They are expensive but worth the extra cost.

We purchased this lock for a storage. We followed the instructions. The lock looks strong but it does not work very well the rotating numbers are difficult to line up and you are never sure whether you have them in alignment or not as there is no definitive click even if you are using any set of numbers (you wouldn't want it to be definitive only when you had the correct 4). I used the code behind the key on the back and got the lock to open then I opened the bolt and inserted the little combination key and rotated clockwise then I set the new code. turned the key removed the key after turning it counter clockwise to set the new code closed the bolt and tried to open it with the new code and it didn't work. Then I tried to go back to the original code but it didn't open so then I tried multiple combinations used the new code but changing each dial either up one number or down one number on each code ring. Then I tried adjusting two at number rings at a time using the same methodology and never got it open again. So, it may be operator error but be careful because your will be in trouble. I thought i followed the intructions to a T but no such luck. Then I searched online to see if there was a number to call to try to reset it since I have the original combo and key. No luck.

Lock arrived all dirty and grimy, as if it had been used and returned. Number wheels are fairly difficult to spin, both due to internal resistance (I hope that will ease in time/use), and the fact that they are recessed a bit so my big fat fingers have a hard time reaching and only spinning one at once. I have to use my other hand to hold the numbers that I don't want to move while I spin others.Otherwise, it seems very sturdy and a good lock for our shared storage unit. I tried to find one that had a combination lock so I dont have to distribute keys.

Very solid, heavy duty lock. Comes with a key (don't loose it!) to reset the combo when you need to. Number dials are tough to turn, but I take that as a sign of it's robustnesss--if you have weak fingers, maybe not the lock you want.

Does what it should, no issues.

While this lock seems to be high quality and works fine, buyers should be aware that it is a product of Master Lock EUROPE and therefore is not supported in any way by Master Lock USA. This has caused a problem for us in trying to obtain a replacement combination change tool. Only one such tool is provided with the lock and if you lose this tiny tool, Master Lock USA says your only alternative is to buy another lock.

Needed a lock for a Pod shipment -This one is easy to reset the combo with the included key, easy to open and easy to lock.Quite heavy and feels like a secure piece of hardware.Much easier to use than those locks with the combo in the bottomI hope I don't need to replace it - but if I had to, I'd get one of these again.

This name brand combination lock is a disappointment. It's solid and heavy duty but difficult to use. The numbers are very hard to turn and must be placed exactly right (which is not right at the marks but a bit below). Because all the tumblers are sunken down the ones on far right and far left are even harder to manipulate. I would send it back but I sprayed it with oil hoping to make the tumblers easier to turn - but that didn't work at all. I will be tossing it. What a waste. I expected a much more thoughtful design and smooth functionality from Master Lock.
