Reliable and Secure – Great Value!
I recently bought the Master Lock 6271KA 2 Pack, and I’m very pleased with the quality and security they provide. These padlocks are perfect for locking up storage units, gates, or even lockers. The set includes two locks with the same key, which is super convenient. Pros: ✅ Durable & Weather-Resistant – The locks feel solid, and the weatherproof coating is great for outdoor use. ✅ Same Key Convenience – Both locks use the same key, making it easy to manage. ✅ Smooth Mechanism – The locks open and close with ease, no sticking or difficulty. ✅ Versatile Use – Ideal for a variety of applications like sheds, gates, and storage units. Cons: 🔸 Dont lose your key lol Overall, the Master Lock 6271KA 2 Pack is a reliable, durable, and convenient choice if you need quality locks for various purposes. Highly recommended for anyone looking for dependable security! 🔒🛡️

Another quality product
Great option for my motorcycle trailer. Lets me keep the ramp door and man door locked with one key. I also like the added security of the hidden shackle. Has worked good for over 7 months for me so far, stood up to the New England winter with no problem.

Fantastic locks
Got a trailer? You need these puck locks. Look, yeah, anyone who has the know-how and tools can get through just about any lock. But your everyday aspiring thief doesn’t have either of those in abundant enough supply to get through one of these bad boys. The only issue I have is that the key will very quickly begin to encounter resistance when relocking. A little silicon and you’re back in business.

As secure as I need
These are the best trailer door locks...Ever! Received 3 locks, as ordered, all keyed alike. The cylinders are smooth & easy, and if installed with the opening down they don't collect rain water and freezing locked is not a concern. This would have been 5 stars all the way, except one set of keys was bent beyond repair. Hopefully I can get copies made locally. The encased bolt makes cutting these off virtually impossible. The previous experience I had with one when the keys were lost required drilling the cylinder and then blowing compressed air in to clean out the shavings. It took me about 5 minutes, but I was being careful not to damage the trailer door. If a their really wanted to just break in I'm guessing it could be done in under 2 minutes... But that's a far cry better than the 2 seconds to cut through a pad lock or one of those storage facility locks. All in all, quite secure, works well, and looks professional.

Very Secure
Very happy with these. Great quality like all their other products. Easy to use. Key fits well and has a smooth operation. You will probably need to pair this with their hasp that matched this lock. The fit is very specific, but that is part of what makes it so secure.
