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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Heavy duty firva combo lock *by on Reviewed in the United States April 13, 2026* Pros: Good quality, hefty, does the truck to secure my garden shed. Easy to set the 4 digit combination just follow the directions.Cons: the rubber flip down flap that protects the number dials falls off easily. Dials only rotate one direction. These 2 things dont bother me or the application fir my lock but others might be annoyed.Would buy again ### ⭐⭐⭐⭐⭐ Recommended. *by on Reviewed in the United States July 22, 2026* 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. ### ⭐⭐⭐⭐⭐ Great lock. *by on Reviewed in the United States August 9, 2026* Good lock. Some lowlife tried cutting it to steal our mini bike. Couldn’t make it through and walked off. It’s possible (likely) that was just a weakling but either way the lock held strong. ## Frequently Bought Together - Master Lock Combination Lock, Heavy Duty Weatherproof Padlock, Resettable For Outdoor Use, Brass Finish, M175XDLF - Lumintrail 12mm (1/2 inch) Heavy-Duty Security Cable, Vinyl Coated Braided Steel with Sealed Looped Ends (4', 7', 10', 15' or 30') (4-FT) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/8321880-combination-padlock-heavy-duty-weatherproof-lock-brass-m175xdlf](https://www.desertcart.us/products/8321880-combination-padlock-heavy-duty-weatherproof-lock-brass-m175xdlf) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-14*
