Review: Buy - I really like these Master locks, I have ordered several of these for almost all my uses. I don't like carrying around a bunch of keys so I use the combination locks. These are extremely heavy duty and easy to use. They hold up to weather pretty well. Sometimes they slightly get a little bit of white crusty corrosion on some portions when they are in contact with a different type of metal but definitely never rust. Good quality lock and wood. Recommend them to anyone for any use.
Review: Solid sturdy lock. Easy to reset combination. - Use this to lock my shed and gates around my home. Log is Master Lock quality and strong. Easy to reset the combination. The little rubber cover is not a great design, but lock still easy to open over the winter even at freezing temperatures.

## Questions & Answers

**Q: I recently purchased one, but the four digit code on the packaging doesn't work to unlock it. What can I do?**
A: As of 5/2023, master lock says you are out of luck if one shows up and the preset code doesn’t open the lock.  I ordered this lock - code doesn’t work (I have a few of these, it’s not operator error), called master lock.  They say they can’t help.

**Q: How many digits are in the combination?**
A: 4 digits

**Q: Can anyone confirm that the numbers do not spin if unlocked, but show the combination? This is a huge security flaw on job sites where it will be left**
A: I DISAGREE with the two other posters.  I just had one delivered yesterday (8/13/19) and am returning it because, among other problems, once it's unlocked, you CANNOT rotate the numbers unless you return the shackle to the locked position.  If you leave the shackle open, the correct combination is there for anyone to see.

**Q: Is it possible to get a replacement rubber cover for the lock? It was delivered with that part missing.**
A: Don't bother.  It'll fall off within days or hours.  The rubber part holding it to the lock is very flimsy and flexible, so it won't stay on.  You'd have to super glue it.  Horrible design.  And the lock can be defeated in 30 seconds WITHOUT any tools.  Someone can identify your combination numbers in 30 seconds or less even if you scramble them.
