Master LockMaster Lock Brass Combination Padlock for Indoor and Outdoor use with Resettable Combination for Gym Locker, Gate, Fence, or Shed Lock, 175D

Very strong and secure lock, ease to use, no key required. I use it on my gym locker, though it is capable of much more. I do this because the thin locks are easily cut by thieves and that sometimes occurs at the gym. This has protected my belongings well for sometime. It is also nice because I can set the combo to something that I easily remember.

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!

Great gym lock. No key to have to worry about. Keeps your things safe.

Great lock! Have many of these and like the ability to have the same combination! Withstand the elements in the environment!

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!

This is a secure combination lock. I was unable to use my decoder lock picks on it due to the tight tolerances. There are ways of popping it open, but the average mook isn't going to do it. For the price, an excellent value.

Works like it should. Am using it outside and no problem unlocking. We'll see if in the future dust gets in a stops it from working.

Love the ability to set my own code. Easy to set and the brass looks like it will be able to withstand the elements
