Review on TOWSMART Trailer Coupler Anti-Theft Lock Kit – Chrome Coupler Lock, Boomerang Hitch Pin, Brass Coupler Lock, 4 Keys – Securing Trailers in Tow, Protecting Unhitched Trailer from Theft by Gary Stringfield

Do you want total security? Well, you're probably going to spend as much as your trailer cost you. Locks are basically deterrents and low-hanging fruit flakes when the tough pro wants to get at your stuff. He'll get your things. When a guy tries to take my classic rollback car no certainty other than the good fortune that I saw him lighting a cigarette in the dark will stop that determination :-) but 99.9% of criminals aren't that smart. looking for easy money and a simple dash or smash and take. This type of lock is VERY effective at doing this and THAT is what most of us really need. Got a race trailer with a half a million dollar car and tools in the back? You probably want more than that. But for most of us. enough. This is a 3 piece set. A corner pin lock holds the drawbar to the hitch. If they can't unlock the trailer, they can try taking the entire trailer and hitch and just attaching it to their hitch. it stops it. It's also a double size that's really slim. thick and thin, and the lock fits on the locking pin located on either end. really cool idea! I almost missed it. The other 2 pieces are for towing, not towing. If the trailer doesn't pull, you put a big red lock in the hitch like it's going to your car. Of course, if the trailer is "in tow," that doesn't work, and that's what a padlock is for. Instead of a safety pin to keep the hitch from popping out, replace the pin with a padlock. Now they can't just unhook the trailer and they can't pull all your traction and steal it like that. 99.9% of thieves see this and just move on. too much work, too much risk, and that's basically what locks are for. containment keep going baby find easier prey. and they do. All in all a pretty decent deal for a pretty complete set of locks and they all have the same keys and you get 4 keys. Good.
