After a year all is still operating just fine. Great product for sure.

by:
Had it on my hitch for a month this spring and then could not get the lock to work and the key was stuck in. Tried oiling and the key finally broke off in my hand. After another couple of months I snapped off the bent end of the pin with a long pry bar. The pin was rusting! Very disappointing for a Master Lock product.
Just got a $xx locking pin through you that looks tougher but it is very hard to use: have to push in on the key pretty hard, while keeping the round lock from turning, and holding in the pin against the pushing on the key. I added a small stainless hose clamp to the lock so that the lock can be held to stop the spinning and hold the thrust of the key.
We trailered our old Ferrari to Florida this spring with the old pin to win our class at Amilia Island – 1946 to 1950 limited production European sports and GT cars. If you check we have a lot of trailer stuff that we got from you in the past and your service and stuff have been great.
by:
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.
by:
This locking trailer pin is an excellent addition for my trailer hitch - which by the way was also purchased from etrailer.com - and was a perfect fit , quite easily installed, and looks good. The trailer hitch adapter (also purchased from etrailer.com) is secured as well as my bike rack. I highly recommend this product.
by:
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.
by:
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.

by:
This is a hard one to review. The product looks to be of good Master Lock quality. I could not actually use though because it did not fit my trailer hitch. It was disappointing because it was recommended by the site somewhere. eTrailer was very accommodating, offering to walk me through returning it. I can't give the lock a higher rating because I couldn't use it but it looks to be of good quality.
by:
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.
by:
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!
by:
Installation was exactly as shown… very prompt delivery too.. excellent customer service

It installed easily and quickly. Good price and fast delivery. This is the 3rd product from etrailer and Curt for me.

Very well.No issues.

by:
The pin lock continues to work very well for all my needs - basket, bike rack, etc. Have not had any issues with it. I do advise keeping it clean and use a little powdered graphite for the best operation.
by:
Unfortunately, the clearance opening in my tailer hitch and bike rack do not line up properly and I have been unable to use this device.
by:
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.

by:
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.
by:
The products that I ordered were perfect for what I needed. Ordering the parts was easy and they arrived in a timely manner. I ordered a locking pin for my trailer hitch and a wire connector protector. Both
Items were as described.
by:
My motorhome hitch did not have enough clearance to use a conventional locking hitch pin but this product has the key hole facing out so it solves our problem.
by:
The perfect security lock for my Thule bike rack. I love the 2 different size pin it come with. Very heavy material and good quality lock. Exactly what I needed to replace an old fashioned bike chain
by:
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.
by:
Sometimes you need to leave your rig parked unattended.
With this locking hitch pin chances are that my ball mount will stay on the pickup not is someone else's.
Looks to be good quality and easy to use.

Thanks!
by:
Swivel head trailer hitch works well, but it started rusting after the first rain. So I don't leave it in the hitch, which means it is not available when I need it.

Do you have a question about this Trailer Hitch Lock?
  • Looking for Keyed Alike Trailer Hitch Locks with 5/8" and 1/2" pins
    Thanks for reaching out John, I'd actually recommend going with our etrailer keyed alike locks instead of the Master Lock # 2866DAT . The Master Lock isn't available as a keyed alike option. There's no way for us to guarantee that two separate locks would come with the same key. Our etrailer keyed alike locks are the better fit since your goal is to have both locks work with a single key. The etrailer Hitch Receiver Lock # e98879 has a 1/2" diameter for the 1-1/4" receiver and # e98882...

  • Can Trailer Coupler Lock Pins be Replaced?
    Hey William, thanks for reaching out! Usually there isn't a way to get just the replacement pin, but if you have a kit like the Master Lock # 3794DAT, we have some of it pieced out and you could get just the locking pins as part # 2866DAT or part # 2848DAT. This would come with an additional lock, but you would be able to simply swap it out to the one you currently have so everything is still keyed alike. If you let me know what specific lock kit you have, I'd be happy to see if we have...

  • How to Install ToyLok Mounted Retractable Cable Lock to 4x4 Bumper on 2020 Alpha Wolf
    The U-Bolt mounting kit that comes with the ToyLok ATV/UTV Mounted Retractable Cable Lock # LC337120-337114 can be found separately as part # LC337114. To mount this to your bumper you'll have to get a bit creative because the U-Bolts are designed to fit 3/4" - 1" ATV-UTV racks so there is no way that they will wrap around your 4" square bumper if that's what you had in mind. Another solution would be to install a hitch receiver on your 4" square bumper, like the Curt # E-100, and then...

    Thank you for your purchase of the Class I 1-1/4" Curt Trailer Hitch Receiver # C11510 for your 2008 Infiniti EX35! When it comes to the wiring you'll have to use a splice-in option and for that I recommend the Curt # C59236. This kit has the black module box that helps protect your OEM wiring and a power lead so your trailer lights will be powered straight from your vehicle battery. To install this you will use the tester to see what wires carry the functions you need to connect to but...

  • Replacement Locking Hitch Pin for Subaru Bicycle Rack Made by Yakima
    Yakima did make the Subaru-branded bike rack but they do not offer any replacement parts directly; these proprietary parts can only be purchased from Subaru. Your Forester could be equipped with either a 1-1/4-inch or a 2-inch hitch receiver. The diameter of the hitch pin will be 1/2-inch for 1-1/4-inch hitches or 5/8-inch for 2-inch hitches. You can measure the size of the receiver opening on your hitch (or the hitch pin hole itself) to determine which size pin you need. If your hitch...

  • Do Hitch Pins and Hitch Lock Have Trailer Weight Ratings
    Standard hitch pins like # PC3 and hitch locks like # 2866DAT do not have specific trailer weight capacities because all of them are capable of towing more weight than any trailer hitch they will fit. You do not need to have any concerns with the weight capacity of a hitch pin or lock.

This cargo carrier weighs 30 lbs, which will allow you up to 170 lbs of cargo.Your Subaru's tongue weight rating is at 200 lbs according to the 2017 Forester Owner's manual.

All of the locks you have mentioned # 2866DAT, and # 7682 will all fit it. They will also fit the Surcp Cargo Carrier that you referenced. Since the Surco is no longer available, you might consider the Reese Carrier # 63155. Out of the 3 locks, I would go with # 5200. These are among our best selling locks.

  • Cargo Carrier And Hitch For 2011 Chrysler 300 To Carry Folding Wheelchair
    If you do not have a hitch on your 2011 Chrysler 300, I recommend a hitch and a cargo carrier.
