Review: Good trailer lock - Great trailer locks. Keys only fit lock it comes with, not universal
Review: Hey, it's a Master Lock, and does its job. - The very act of purchasing a lock means you want to protect that item you are locking; don't scrimp and save a few dollars and buy an off-name brand, buy this Master Lock. Lost my keys to my other hitch lock and had to cut it off with bolt cutters; this Master Lock is to replace it. I have trusted Master Lock brand for 50 years, which influenced my decision to purchase this item. Solid, seemingly good quality, I'm sure it will work fine for years.

### ⭐⭐⭐⭐⭐ Good trailer lock
*by B***N on April 23, 2026*

Great trailer locks. Keys only fit lock it comes with, not universal

### ⭐⭐⭐⭐⭐ Hey, it's a Master Lock, and does its job.

The very act of purchasing a lock means you want to protect that item you are locking; don't scrimp and save a few dollars and buy an off-name brand, buy this Master Lock.

### ⭐⭐⭐⭐⭐ Where's the Lock??
*by M***S on January 27, 2026*

I give this Product 5 Stars because I have had this product on many different trailers and they last forever. Great Product. But, this time I receive my order and open the bag and there is only a set of Keys? The lock was obviously cut off the product packaging because there were white zip ties that were cut. Amazon doesn't have an Option that the Item I ordered is Missing? First time this ever happened to me. Now I have a date to return the so called Defective Item that I never received or I have to pay again. I am not to happy to have to drive accross town to a UPS Drop Off site and drop off a set of keys? Well........What can you do. Anyway. This is a weird review I know. But product is superior if ya get it. LoL. 8o)
