Review on 🔒 Secure Your Trailer with the Master Lock 389DAT 2 Pack Coupler Lock - Red by Brandon Havlicek

The lock works fine. It's easy to put on, easy to remove. The problem is the keys. They are made of such soft metal that they are very difficult to pick when the locks are exposed to the elements or when it's cold outside. The keys bend before the lock turns. I've tried the locksmith's lube, but the keys still flex against the lock with little resistance. I broke 2 keys in winter when the locks were so cold they wouldn't open. I could pull the keys out with tweezers and swear in the cold for an hour. It's actually a good lock, so if the weather in your area never goes below freezing, you won't want to get the locks dirty and fish out the keys. when they break off. To be honest I've tried removing the lock without a key and it's not easy.
