No complaints, arrived with three keys which is a plus.

So worth it to have all of these things keyed the same!! Great lock set.

Was really looking for the ball lock. I got way more than I was expecting. This seems bulletproof...

Great product, will order another for my other trailer

Product came as listed. Customer service has been very thorough.

by:

Nice compact easy to use and shipping is always fast.



by:

I bought and returned 2 different coupler locks that didn't fit my new camper(Amazon and Wal-Mart). This set works great! etrailer has never disappointed me.



by:

Great price for a good product to keep casual thieves at bay. The kit is well made, I just need to see how well the finish on the pins holds up to road salt spray in the winter.



by:

The hitch ball lock is coated with what feels like a rubberized paint. Not much chance for rust. The other locks work great and i appreciate the kick covers. I’m very confident that they will prevent the non professional theif.



by:

I'm overall happy with this lock set, except for the receiver hitch pin is to short, my truck has a 3 inch receiver hitch, the hitch pin wont work.

Do you have a question about this Trailer Tongue Lock?
  • Best Trailer Locks to Help Secure Your Trailer
    Yes, we do! A great all around option is the Master Lock Trailer Security Set, part # ML44VR. It comes with an adjustable coupler ball lock, a coupler latch lock, and a locking hitch pin, and they're all keyed alike so you only have one key to keep track of. It's a solid setup if you're looking for a convenient way to add some extra security to your trailer. That said, we also carry heavier duty locks depending on your trailer and what you're trying to protect. If you're mainly looking...

  • Will the Curt Echo Brake Controller Work w/a 2025 Tesla Model Y?
    Yes, it does David. The Curt Echo Wireless Brake Controller item # C51180 will plug directly into the 7-Way connector on your 2025 Tesla Model Y Long Range. You will then be able to connect the 7-way from your Casita trailer to the opposite end of the Curt Echo item # C51180. Have you had a chance to tow with your Tesla yet?

  • Will Master Lock Trailer Coupler Lock Fit Demco eZ-Latch Coupler
    Hi Robert; the pin lock that comes with the # ML44VR will work but I've seen some issues with fitment for the surround lock on your coupler style because of the shape and design. Some people have had success with it on that Demco eZ-latch but I'm not overly confident. Are you wanting to upgrade from your current lock? You could still get the Master Lock Hitch Receiver and Coupler Latch Lock Set # 2848DAT which excludes the surround lock so those are keyed alike and then get a different...

  • Availability of Lock Set for Trailer Coupler and 2-1/2 inch Hitch
    Hey Tim, we have the Trimax lock set part # TMX86SR that is a similar multi lock setup that comes with a locking hitch pin that is long enough for a 2-1/2 inch hitch like you have. These are all keyed alike as well. What are you towing?

  • Recommended Keyed Alike Coupler and Hitch Lock
    Hey Heather, unfortunately the Master Lock Trailer Hitch Receiver Lock and Coupler Lock Set # 3794DAT is keyed unique so it's not available to be keyed alike. Instead, you'd have to use something like the Master Lock Set # ML44VR which come with all three locks keyed alike. This kit also works with 1-7/8", 2", and 2-5/16" ball couplers and 1 1/4" and 2" trailer hitches. If there is anything else I can do for you, please feel free to drop a comment and let me know!

  • What Locks Can I get Keyed Alike to a Lock I Already Have on my Trailer
    That's a really great question, Donald. The short answer is yes, some of our locks can be keyed alike, but not all of them. The key thing to know (no pun intended!) is that locks can only be keyed alike within the same brand. So, for example, if you already have a Master Lock, you’d need to choose another Master Lock that offers the “keyed alike” option to match your existing key. When you’re browsing our locks, check out the filter menu on the left side of the page, there’s an option...

  • Will The Master Lock Coupler Ball Lock Set ML44VR Fit 2" and 2-5/16" Ball Sizes?
    Hi Splash Man! The Master Lock Set - Coupler Ball Lock, Locking Hitch Pin, and Coupler Latch Lock # ML44VR will actually fit 1-7/8", 2", and 2-5/16" couplers, so you are good to go there! It's pretty versatile. That said, they are not able to be keyed alike, unfortunately. This goes for all the kits like this we have. All the pieces included with it are the same key number though. There is a chance that ordering two will end up having the same key numbers, but there is a pretty wide...
