Master Lock Universal Trailer Coupler Lock is rated 4.0 out of 5 by 10.
Rated 2 out of 5 by from Basic lock Will provide more protection than a pin style lock, however not as comprehensive as one with the steel bar and ball. I would spend a little more money and get a coupler lock that is extremely difficult to remove/break/unlock.

Rated 5 out of 5 by from Strong and easy to install! Strong and easy to install. Feels good knowing someone can’t hook up and steal my trailer.

Rated 4 out of 5 by from Good visual and practical deterrent. We purchased this recently to take on a camping trip with us. I kept reading online about people having their camper stolen right from the campground or from parking lots where you leave it when you are sightseeing in between stays. It’s easy to use, seems like it would fit pretty much any hitch, and provides a very visual deterrent for someone who might be opportunistic and looking for a camper or trailer. They would pass ours by and go for something else if they saw this is the way we thought about it. Overall a good product at a good price.

Rated 3 out of 5 by from Size matters I bought this to go on my Jayco flight. The ball does not come all the way off and my tongue has a bit of a lip around it. I had to file down the lip of the lock to get it fit into my hitch and lock. It could be improved by being able to remove the ball all the way, insert it into the hitch and then reattach it to the rest of the lock and lock it.

can i get keys if i lost mine

Asked by: Ed17
Hello. There should have been a key code stamped on the key. This code can be taken to a local Tractor Supply store to have a new key cut. Please call in advance to ensure this service is available at your location.
