Review: Solid lock for multiple users - Very solid lock and perfect for gates or anything outside in the weather. We love it because you can set a combination for your individualized needs, and change from time to time to maintain security. Also because we can share the code, for example, give code to our lawn maint folks so they can access a locked part of the yard anytime vs our having to unlock it for them. Only thing I did NOT care for is that we have bought these over the years and they last a long time. However, on this one the keypad cover has been really cut back, VERY thin rubber now, and will not stay shut. So therefore its pretty worthless. I did not reduce the rating due to that as its easy to keep the lock sprayed with lubricant, but come on Master Lock, stop going backwards on your products!
Review: Recommended. - Bought as like new or used: very good, but the plastic bumper ring around it was broken, more cosmetic than functional, I believe it was going to break eventually anyway. If that's a concern, just rap some rubber bands around it. The lock is very sturdy and the rubber flap that covers the combination underneath appears to be sturdy enough, moreso than the plastic bumper ring. Works well, smooth operation, very sturdy, and the combination was easy to reset to one of my liking. I think I'll hose it down with spray lube to prevent deterioration once or twice a year. Could have chosen a cheaper knock off that would have worked well, the technology is not rocket science. I'm happy with the Master lock, I believe it's probably more refined than a cheaper alternative and some needed a tool to reset the combination which was about as desired as having to keep track of a key (not a desirable feature for me, partially defeats the purpose of this kind of lock: simple security if not top flight). The construction is top flight but a four digit combination, by nature is not, but I opted for simplicity. The construction, materials and sturdiness are excellent and maybe over the top for this kind of lock, but it's what I wanted. Looks very secure and in security: perception is reality 90%+ of the time.

## 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.

### ⭐⭐⭐⭐⭐ Sturdy and convenient!
*by E***U on October 14, 2026*

I love this lock! It is far more sturdy than the one I had on my storage room before. Somebody cut that one and went right in and trashed my stuff. I love not having to have a key every time I happen to be driving by and wish I could stop.
