    • Easy to use

These are great little locks. I use them outside and they don't seem to mind the rain. Easy to program...works every time.

    • Rugged and functional
Size: 2 Pack Style: Number Combination Pattern Name: Lock
These are strong and durable. We have quite a few of them scattered across the farm - on various buildings and vehicles. The ability to set the combination is invaluable for us. It is easy to set them all the same so we only have to remember one.

    • These work!
Size: 4 Pack Style: Number Combination Pattern Name: Lock
They have short comings for daily use in all weather, but those can be worked around. First the brass number wheels tarnish and get difficult to read. This can easily be cleaned off which I do about once a year when I lube them up and get them ready for winter. They will freeze up if wet when frozen, but fortunately they can easily be thawed with boiling water or lightly warmed with a propane torch. Once dry the cold doesn’t matter much. If really gummed up so they’re not relocking a few taps on the side of the lock will get it locked until you can clean it up! Towing as a trailer hitch lock it for hours through a blizzard didn’t change it’s normal behavior. A tea kettle full of boiling water got it unlocked and the trailer unhitched in record time. I continue to get good use out of these year after year! ... show more

    • Good locks
Size: 4 Pack Style: Number Combination Pattern Name: Lock
Works as a lock should, keeps the honest thieves out of your stuff. Comes with the “key” to change the combo and very easy to do. Haven’t ever had to cut one so I can’t tell you how strong it really is but I figure it’s about average.

    • Durable and Versatile Combination Lock
Size: 1 Pack Style: Number Combination Pattern Name: Lock
We absolutely love our Master Lock! The combination feature is super convenient—no need to fumble with keys, and it's easy to set your own code. The lock feels really sturdy and well-built, giving us peace of mind knowing our expensive items are secure. We’ve used it to lock up our E-bikes and also on a storage unit, and it’s held up great in both situations. The heft and quality of the lock make it feel really durable and reliable. It’s reassuring knowing that it’ll withstand the elements and keep our stuff safe. If you need a solid, trustworthy lock for anything valuable, I highly recommend this Master Lock. It’s tough, secure, and has definitely earned its place in our everyday use! ... show more

    • Comination Master Lock 4 pack
Size: 4 Pack Style: Number Combination Pattern Name: Lock
Purchased in December 2025 pack of 4. Installed 3 immediately on my trailer after setting all 3 with same combination. Tried to open each today 2/20/26 none would open with combination I set. Wasted over an hour working with them. Used oil and striking locks finally opened. Afraid to use again. Wasted my time and money. Of course after 30 day return time. ... show more
