  • They get the job done
Style: Combination Lock, 2 Pack
I have three of these locks on my outside gates and shed. It's great that I can use a code to open them instead of looking for a key. They feel sturdy and with the locks located inside the fence I don't see anyone trying to pick them anytime soon. They have been outside for about a month now and function like the day they were put out there. ... show more

  • Heavy and handy
Style: Combination Lock, 1 Pack
I have a few storage sheds and used to have military style pad locks which required a key. I was hesitant about using combo locks because the ones I saw were light weight and apparently not well made. These Master locks are heavy weight and obviusly well constructed. It sure beats having to back into the house to get a key. Very handy and I feel confident they do the job. No I didn't get paid to rate this 5 stars. ... show more

  • Solid lock, easy to program
Style: Combination Lock, 1 Pack
Well worth a couple more dollars over other locks. I’m sure it could be cut, but it’ll discourage most people from trying.

  • Holds up and No Issues
Style: Combination Lock, 1 Pack
Many locks claim to be outdoor rated but end up rusting over anyway. This lock is the real deal, no signs of any rust and still operates smoothly, this has been used outdoors in CA weather.

  • Super high quality lock
Style: Combination Lock, 2 Pack
They look good, it is great not to have to fumble with a key, and the quality is outstanding. I've got 6 of these so far (first time double pack, and then came back for more). The brass, on the bottom, where the combo lock is, is really cool and the lock seems indestructible. One of the six was a little fussy at the beginning, did not want to open easily, but after messing with it for 5 minutes, it worked perfectly well. Amazing locks. ... show more
