You really can’t go wrong with anything from E Trailer. It does exactly what it’s designed to do.

by: Keith 08/23/2024 One Year Later

I have owned two of these for a year now. And both of them are still in excellent shape the one on my truck and camper stay on year round.And neither one of them show any wear at all. And both work flawlessly yet. If you want a coupler and hitch lock keyed the same. I would highly recommend you by this set. And you can't beat trailer price and shipping rates also.

i own 2 sets of these and they both work the same as the day i bought them. They are a must have if you want a high quality keyed alike coupler lock and trailer lock. i leave them on both of my hitches and trailers year round. and they both work flawlessly when i switch my regular trailer hitch to my camper hitch om my truck. highly recommend them.

I trust Masterlock plus I already have this lock system for another vehicle and love it. My old set is about 9 years old and still works great.

Michigan uses salt on their roads and this Master Lock is still working like the day I bought it. Our roads are some of the worst in the country with rusted out vehicles and things like that. It may not shine like a new penny, but its completely functional.

I still have the Hidden Hitch ball mount and the Master Lock locks. Theball mount is great. My only knock on the locks is the flimsy dust coverthat covers the key holes. The narrow strap that attaches them broke aftera few uses and the caps dont stay on well. I use a piece of duct tape oneach lock to keep the dust out, since Im often going down gravel or dirtroads with the trailer.

by: LaVern H. 10/06/2017

I think that master lock makes a great lock. I like that the hitch receiver & coupler latch lock is stainless steel & won't rust. I will be using the locks when I am pulling my UTV trailer. And now I have less keys to carry. I would recommend this combo lock set to anyone.

My stainless steal Master Locks for my receiver hitch & trailer hitch lock are still working great for me. I like that I only need 1 key for both locks. Im loving my locks.

Excellent product.

by: Joseph A Marie Jr 01/18/2014

Excellent product and excellent service. The product arrived sooner than expected and that is really appreciated. I will be ordering an aluminum ball mount soon as I like the hitch and all accessories to be as rust resistant as possible and the ball mount as light as possible. Thank you very much

The product is still in excellent condition and have had no problems.

by: Scott Y 09/29/2014

So, the hitch receiver looks well made and makes a tight fit to reduce the chance of cutting.

The hitch lock on the other hand does not tighten up enough leaving the shaft exposed to a hack saw. Too bad.

Patrick B.

Yes, you could get a hack-saw on the lock. The bar is solid 58 inch stainless steel. It can be cut with a hacksaw, but youll be there for a bit, and thieves dont usually hang around long.

Outstanding product. Still look and act like new. With these I know my trailer is secure to my hitch and my hitch is secure to my truck.

First order for a hitch and wiring kit arrived quickly. However, the wiring kit packaging looked damaged and was missing the main electrical adapter. Customer service was very helpful and shipped replacement harness quickly. Giving 4 stars for the original order being packed incomplete.

by: Francis 09/01/2020

Does the job, easy to use, nice to have one less key to keep track of. I really like the sturdiness of the hitch lock. The coupler latch lock feels like it would be simple to break for the determined thief, but it serves its purpose as a deterrent for the casual criminal. The rubber lock cover was ineffective; after a night of rain, the lock had plenty of water in it under the cover. Probably best to point the lock towards the ground if you are concerned. But at this price, I don't expect it to last forever anyway.

by: Leslie R. 08/25/2017 One Year Later

Performed very well and still in good shape after towing light camping trailer over 10,000 miles on a 3 1/2 month trip. Lots of hitching/un-hitching. I found these easy to use and have been very pleased.

by: Jim 03/11/2021

This product is stainless which its excellent for the hitch pin and lock as it's always outside in the weather. Both pin locks are keyed alike, simplifying locking & unlocking. I made the mistake of going with the cheapest shipping with the postal service. It took 10 days to get here. Otherwise everything was excellent.

by: Christopher 11/15/2022

Out of three items I ordered, I only received the ball mount and lock, no ball.
The two items I did receive are well made and fit with no issues on my 2018 aftermarket hitch. The ball itself has not been shipped and the expected delivery date is over four weeks for delivery, so I can’t comment on it or the whole unit as a whole.
Terrible shipping , but quality ball mount and locks.

I have ordered from them on a few occasions. Everytime, shipping is quick. Prices are reasonable.

It has been working perfectly well

by: Dan B 10/12/2011

the number of keys we need to carry around. I like the dustcover over the lock, it fits well. Both locks fit tight against my hitch/ball lock, which makes it harder for someone to get in there with anything to cut them.

by: Glenn 10/20/2021 One Year Later

It's a little wonky to lock as the interior bolt has to find one of the relief grooves in the shaft. You will get used to it. My trailer has not been stolen, nor has it jumped off the ball on rough roads, so the lock does the trick.

by: Mark 09/15/2022

1st time customer. Great experience start to finish. I really enjoyed "seeing" the people who made it happen on the shipping confirmation email. What a great way to honor the employees. I also want to provide positive feedback on how the order was packed using a high quality box designed for heavy items with convenient side knockouts for hand holds. So maybe the dozen or more staples securing the top was overkill (ended up cutting top off instead of pulling staples) but the package was 100% good condition when it arrived. I was also surprised and pleased how quickly it arrived. The tracking tool on the email was quick and convenient. I will be ordering again when I rehab a 5 x 10 landscape trailer I had custom built 25 years ago. Thanks!

Totally painless dealing and FAST! I would have had to drive miles out of my way, but instead it comes right to the door. I really like the double lock package with a trailer hitch lock and the tow receiver lock that are keyed alike. Thanks and I'll be back for more.

by: Bill S. 07/10/2013

This product gives me a better sense of security when pulling my new trailer. Finding a trusted name like Master Lock with both the trailer coupler and the receiver lock both keyed alike was also a big plus.

Keyed Alike Hitch Locks for 2-1/2 Inch Receiver and Trailer Coupler Latch
Although it isn't sold as a kit, we do offer a hitch lock that's compatible with a 2-1/2 inch receiver and a coupler latch lock that can be keyed alike. For the hitch lock, use # e98881 and # e98886 for the coupler latch lock. On the product page for both items, right above the 'add to cart' button there's a drop-down menu where you can choose the option of a keyed uniquely or keyed alike lock. If you choose the keyed alike option on both locks, they will be keyed alike for the same key. I've...

Does Master Lock Hitch Pin Lock Have Weight Capacity
Great question Shaun, so hitch pins like the Master Lock part # 1481DAT are not weight rated because they don't ever really fully take on the weight of the trailer so it's not realistic to give a number. We've had our hitch manufacturers tell us the hitch would fail before the hitch pin would.

Availability Of a Keyed Alike Hitch and Coupler Lock With a Coupler Latch Lock Wider than 1/2"
You are going to want the Master Lock Hitch Receiver and Coupler Latch Lock Set # 1481DAT as it has an adjustable coupler lock which fits multiple coupler latch sizes. This like the etrailer Hitch Receiver and Coupler Lock Set # e99039 you found will fit a 2" wide class IV receiver with 5/8" diameter pin. We do also have the etrailer Hitch and Coupler Lock Set # e68ZR which will also include a storage lock to keep your trailer safe when not connected. And finally we have the larger 2-1/2"...

Comparing Master Lock Hitch Receiver and Coupler Latch Lock Sets
The main difference between the Master Lock Hitch Receiver and Coupler Latch Lock Set part # 1481DAT and part # 2848DAT is that the former is for 2" hitches and the latter is for 1-1/4" and 2" since it comes with both pin sizes (1/2" and 5/8". The locks are both very similar, I wouldn't say one is more secure than the other.

Coupler Latch Lock Pin Recommendation for my 2-5/16" Coupler
The etrailer Surge Brake Coupler Lock part # e98887 is perfect for your needs. It has a 2-1/2" useable span and is 1/4" in diameter. This is the size they use for these. I understand it is 1/32" smaller that your request but it is designed for your purpose. I've included a video I did on the lock for you to check out and see some more specifics on it.

Is there a Weight Capacity for the Master Lock Hitch Receiver and Coupler Latch Lock Set
Hitch pins and locks don't actually bear any of the weight of a trailer or accessory so they don't have weight ratings. The only weight capacities you need to consider are for the tow vehicle, the hitch, ball mount, and hitch ball. The tongue weight of a trailer puts so much downward force on the ball mount that it binds it up so well in the hitch that the hitch pin doesn't actually have any force put on it. The hitch or ball mount would fail before the hitch pin would. The pin hole for...

A-Frame Coupler Lock for Wide Latch
There is a solution for you, though the Master Lock Hitch Receiver and Coupler Latch Lock Set # 1481DAT will fit coupler latches that are 2".

Trailer Coupler and Hitch Lock Set for a 2013 Subaru Outback Wagon and A-Frame Trailer
The Master Lock hitch and coupler lock set # 1481DAT includes a coupler lock (the smaller one) that would fit in a hole on a latch style coupler provided that hole is 1/4 inch in diameter (which is industry standard). With the lock in place whether towing or not towing, the latch cannot be opened so it could not come off the ball or be placed on a ball. I have included a picture that shows the hole in the coupler I mentioned. If you have a different type of coupler this type of lock may...

What Coupler Lock Set do you Recommend for My Coupler and Reciever
With the Master Lock Hitch Receiver and Coupler Latch Lock Set part # 1481DAT not meeting your needs in function I recommend using the etrailer Trailer Hitch Receiver and Coupler Lockset part # e99039 instead. These utilize a screw together lock set that work very very well. I like the coupler lock much more that the one that comes with the Master Lock set because it is not as long. The etrailer lock will snug right up against the coupler latch and will help prevent theft.

Locking Pin Set Recommendation for Buyers Products Coupler w/ 3-Position Adjustable Channel
I recommend using the Master Lock Hitch Receiver and Coupler Latch Lock Set # 1481DAT to lock your ball mount to your tow vehicle as well as the Buyers Products Coupler w/ 3-Position Adjustable Channel # 3370091553 to the hitch ball. This kit comes with both the coupler and hitch locking pins which are keyed alike so you only need 1 key to unlock them.

Can The Kuat Hitch Lock # HL2 Be Used For Towing Applications?
You will want to use the Master Lock Hitch Receiver and Coupler Latch Lock Set # 1481DAT when towing with a 2" receiver. This pin is 5/8" diameter to match the receiver and ball mount. The Hitch Lock for Kuat Bike Racks # HL2 is only 1/2" in diameter and was specifically designed to be used with a Kuat bike rack only for securing the rack to a 2" receiver.

Is There a 3/8" Pin for a Coupler Latch Lock
The pins used in the latch hole on a trailer coupler are not actually holding anything together. They are simply an anti-theft mechanism which stops anyone from being able to open the latch and either uncoupling or coupling the trailer with the pin left installed. I supposed they could also be looked at as a fail safe while out on the road as well. That said, the pins are all 1/4" so I think the manufacturer may have confused that part.

It has a 5/8 inch diameter, 2-1/2 inch span to fit the 2-1/2 inch overall hitch width. The # e98881 lock is for 2-1/2 inch hitches (inside width of receiver) and the recommended lock, # 1481DAT is for 2 inch (inside receiver width) hitches.

Which Hitch Pin Lock Set Works with Aluminum Ball Mount Kit # AM3410
Thanks for your recent purchase!! What I recommend is the trailer hitch lock # AM3492. It is 4-1/4 inches long and will work with the aluminum ball mount kit # AM3410. The hitch lock # AM3492 will also include a hitch pin lock and both keys are keyed alike. The Master Lock hitch lock set # 1481DAT you referenced will not work with the aluminum ball mount kit # AM3410 because it's too short. It's only 2-3/4 inches in length. I included a couple video reviews too.
