This is a solid, easy to use hitch lock. Unfortunately the rubber dust cover snaps off very quickly. Not a big issue unless you do a lot of towing in muddy areas.


Excellent lock and well made. I really like that the lock swivels. Makes it so easy to unlock. Thanks to Justin for helping me with my order.

excellent purchase. My son just bought the whole trailer set up as well.

Great products and communication. Installation instructions were detailed and complete, no missing parts, and I was able to finish attaching my wife's new wheelchair carrier quickly since all of the hitch parts arrived here in Canada super quickly, undamaged, and fit together smoothly. Thanks etrailer!


Great quality products

The swivel lock system is working great one year later!

Absolutely perfect. Even better than e xpected!


Exactly what I wanted. I can now lock my bike carrier or my trailer hitch to my vehicle with ease.


It was too short to fit through the hitch and connect the lock so I never got to use it.


This is very easy to use, fits both 5/8 & 1/2 inch receivers, and seals nice.


I had to wiggle this lock pin around to get it inserted into the factory hitch receiver of my 2020 Explorer ST. Hopefully it will come out easily when the time comes. I am disappointed that the chrome finish is showing some surface rust, but it is not visible behind the hitch cover without looking closely.


Got the delivery on time. Watched the video before installing the hitch. I had it installed myself in less than one hour on the ground with 2 jackstand supporting the hitch. Great video instruction. Will buy more products in the future. Thank you.


Worked great to keep the [trailer] secu re


Liked my first time etrailer ordering and delivery experience. Master hitch receiver lock exactly what I was looking for. Very satisfied. Etrailer will be my go to choice when future trailering equipment needs arise.


Keys don't fit that well into lock; worry they may get stuck in lock mechanism

I will have our customer service team reach out to you. The lock does have a limited lifetime warranty.

I just put them on my receiver so I don't know yet how they will hold up under load. They appear to be made well enough to keep honest people honest. Though I'm pretty sure a good whack with a hammer would open them up.

They are working well after a year on my truck. The rubber keyhole covers fell off in about 3 months. So no protection from sand I live in Florida getting into the lock itself. Just have to them clean and lubed.

Just what we needed to secure our bike rack to the hitch receiver. Great price and fast shipping


Decent lock


Works great - no problems


Great product and very helpful customer service from etrailer.


This product has proven to be most versatile. I have used it on my Harley Davidson and my truck. It has protected my custom rack on my trike, and the hitch on my truck. It requires only minimal upkeep. I oil the unit lightly before each use. To maintain maximum ease of usage. I use the small pin on the trike and the big pin on on my truck. Great product.


Been using this lock for over 1 year and it still is providing excellent security and safety to the boat-car connection.


Perfect security!


Unique company with great products


Ok. Lock can be touchy to actuate at ti mes


This locking trailer pin is an excellent addition for my trailer hitch - which by the way was also purchased from - and was a perfect fit , quite easily installed, and looks good. The trailer hitch adapter (also purchased from is secured as well as my bike rack. I highly recommend this product.


The locking hitch pin made by MasterLock is one of the better locking pins I have seen - very 'beefy' and well constructed. The locking head swivels so I can access the key slot as it is facing me, versus the others that have the key slot facing to the side of the vehicle which makes it difficult to see if you are trying to find the key slot in the dark. The only minor drawback is that the rubber protective cap that is attached is a little loose and falls away from the lock mechanism occasionally and needs to be put back on again. Nothing a couple wraps of electrical tape didn't fix.
