Great lock for my trailer. I have had it for a while now and no rust. It installs and removes very easy. Light weight and good look.

Though all security locks can be defeated with time and the right tools, this set allows you 3 different layers which simply makes it more difficult for a thief to bypass. Hopefully forcing them to move on to an easier target. Made from good materials, this Master Lock 3 piece set are all keyed the same so having 1 key for all is very convenient and easy on the key ring. I’m very pleased with overall function of this set and consider it a good value. 5 stars

This lock set from Master Lock works great for both my boat and travel trailers. The key fits every piece in this set which is really what you want. Make note that this set is primarily for a 2" hitch receiver and the hitch pin locks won't work on anything larger. I have a 2-1/2" receiver on my Super Duty and it isn't long enough to go all the way through.

Wanted an insertable locking piece to go in the ball socket of the trailer's tongue. Having matched keyed locks for the latch and for the truck's hitch plug-in really saves on keyring clutter, and Master Lock is always good quality. Highly recommend.

Too easy to get off however I have many anti theft devices on my travel trailer and any one of them is easily dismantled but the noise that is made and the time taken to dismantle them all works as a major deterrent.

Very needed item in my area as trailer theft is through the roof currently. It won't stop them, but hopefully it'll slow them down enough that they'll consider moving elsewhere. Worked as expected, would buy again.

The pin locks are fine, maybe a little thin. But I guess they need to be, But I really don't like the ball lock. Too much effort to getting it placed just right to lock it. I wlll say that I like having just one key for all the locks.

Bolt for the truck hitch is far too short. I had to buy a different one.

Overall this is a good setup and the locks are quality products. Only problem is the receiver lock is short and doesn't fit the 2022 Tundras. May just be a problem on the Toyota hitch.I tossed the box before fitting so I can't return. Not a big deal. Just would have been nice to be able to lock the receiver as well.

The hitch pin is a bit tricky to ensure it is on, but works fine, nice finish; great system.

Piece of junk!!! don't buy this crap. You can remove the plastic blue cap and remove the lock pin with out using a key. is this some kind of joke? I have to buy a whole new kit package to be keyed alike. this here pile of garbage is going to the garbage. It wasted my money and time.
