Durable and Versatile Combination 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!

Good locks
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.

Great lock if you have good eyesight.
works like a charm, sadly the numbers are small and not easy to read for old folks like me.

Great Buy!
Extremely durable and easy to use; the resettable combination is seamless, and the brass construction holds up perfectly against the elements.

Time will tell, but so far so good
MUCH better than their cheaper, low-end combination locks (similar shape). Looks like it would slow down an honest thief. I took one star off because of the pictures of a corroded bottom plate in several other reviews. Shouldn't happen.

Comination Master Lock 4 pack
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.
