Got weatherproof lock?
Have been using this for 3+ months on my outdoors side gate. So far holding up well. No problems.... yet.

Great in different weather conditions, easy to use to set code & re-code when needed.
We have bought these for years. We find them easy to code & re-code. We mostly use them outdoors in a marine environment, and have had to replace one or two at that location over the years. For the most part, they are great in that element (rain/wind/salt water air), with minimal corrosion, and very rarely lock up. Indoor use, we have no issue with them, and appreciate the heft & caliber of the metal is great. ... show more

I purchased this lock for a Second backyard gate I didn't use. Locked it and walked away. 1 Year later, I came back to the gate and was surprised to see this amount of rust on the lock. Also, the protective Rubber door on the bottom was open. It did not stay shut. The lock still functions fine and unlocked without any issues. ... show more

CAUTION!
Be VERY CAREFUL when you set the combination on this lock. After you set the tumbler wheels to "your combination", and BEFORE re-inserting the shackle, CHECK, CHECK, AND DOUBLE-CHECK that the tumblers have not moved. I just goofed this and now I'm out $22+ dollars for a lock I can't use. My fault, and I'm not blaming MASTER LOCK, but again, be careful. Pros: It's a MASTER lock. It's heavy-duty, well-built and I'm confident that it would have worked as well as the other MASTER lock's that I have used for years. Cons: a) English is not the first language presented on the instruction sheet and the instructions are in very, very fine print. b) The number centering on the combination wheels, IS NOT in the center of the lock. Don't know why they designed it this way, but I'm sure there's an engineer somewhere that had a reason... ... show more

Stands up great to summers and winters
This lock has held up amazing over three 100 degree F summers and snowy single digit winters. The instructions were easy to follow and the lock still works smoothly after these couple years. The only tiny down side is that the little rubber cover over the numbers does fall off sometimes. It’s easy to put back on as long as you can find it. Definitely recommend ... show more

feels heavy in hand
feels heavy duty, like it has some weight to it. roller can be a little tricky but overall, I think it's a good lock. my only complaint is the little rubber cover on the bottom does not stay on very well. would buy again
