Good layers of security for your trailers and hitch

Reviewed in the United States on March 20, 2024

Verified Purchase

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

Good value

Reviewed in the United States on October 13, 2021

Verified Purchase

Nice combo set. Good value. I'm sure this won't slow down a determined thief with the right tools very much but will at least make it a harder for the lazy ones looking for a grab and go. Just make sure you spray the lock internals with a little lube. Mine were kind of sticky and hard to unlock when I first got them but fine after that.

Very secure

Reviewed in the United States on August 2, 2023

Verified Purchase

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.

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

Receiver lock not long enough.

Reviewed in Canada on October 23, 2023

Verified Purchase

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.

Hitch pin locked in place you can removed by removing the plastic cap don't need a key.

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.
