Does not for my 2 in coupler. Pic sent.

This coupler lock is meant to work with couplers that have a flat lip like part # DM14976-52. The lock recommended for your coupler is part # C66DR.



I looked up the part number you suggested. That will not work on the trailer as there is no place to put the lock through anything. It has to be a lock that goes up inside the coupler. The latch flips down to secure it and there are no holes for through locking. If you can recommend the correct lock I’m happy to buy it but I don’t want to waste money on locks that don’t fit like the one I purchased already.

My apologies as I picked the lock for the Demco EZ latch couplers, however looks like yours does not have the hole in the side for it to slide through. In that case then I recommend part # TMX77FR instead.


Most coupler locks won't fit on our vintage camper because the ball closure sits on top. This lock is compact and does the job great. Very pleased and the price was reasonable.



Still working great. No worries about theft.


The coupler lock was exactly as etrailer described and easy to use. Ordering was easy and delivery was quick.



Works great. Very easy to install and remove.


I order 2 of these and one of them came with the key in it. The slot the key fits in was pulled out with keyy in it.I think I got it in right. Someone tried the key and pulled all the guts out. I wish I would of taken pictures!

These locks should come with two keys each. I see that you wanted them to be keyed the same. With these locks we will take the lock cores out to key them alike. I suspect this was a shipping error. I will have our Customer Service team reach out to you.


Bought this for my boat trailer. Very well made and it's going to be a relief knowing it's secured.



All is working fine with no issues


These work okay. It's also nice being able to have all of the locks keyed the same.
I purchased two, One for a 2-5/16" coupler a year earlier and this one for a 2" coupler. The larger one is still working okay, but this one failed after about 9 months. Not sure if defective or poor quality. Waiting to see how the other one holds up.

We would appreciate an update to your review of your experience and how your new item is working for you.


It works well ! And a great replacement. Easy to install!


Looks well made. I would recommend.



Perfect. Know way your taking a trailer with this on unless you carry it away or use a blow torch.


I like that it has a tighter fit than other locks


Good value. Easy to use.


I just looked inside of the tire cover box.  The hitch lock was in there.  No markings, no indication that misc. Items were in the box marked as the tire cover.  Good thing that I looked as it was gifts for two separate people and the boxes would not have been opened until Christmas.

I suggest a note or something be placed in the packaging box if multiple items will be placed into other boxes.


This lock doesn’t fit my Atwood style coupler even though a picture in your product reviews show it installed on a coupler that looks identical to mine. Perhaps some work with a file, grinder or dremel tool would modify it for acceptable use, but not what had planned for the money.

Etrailer Expert

Jenny N.


You mentioned that the lock was not fitting your coupler. I wanted to ask how it is not fitting. How wide is your coupler? How thick is the lip on the coupler?


I have only installed on one trailer that I don't use often but the device seems well made easy to use and I am happy with my purchase so far.


Fits great, easy to use and I feel secure that no one will be able to hook up to my trailer! Great security investment, highly recommended.


Same as my above review

Scott E.


is working as it should. Also keyed as my other locks, so is handy.


1 year followup: Very pleased with this set of 5 keyed-alike locks. With 3 boats and 2 travel trailers, digging for the correct key was always a pain. Now one key unlocks them all, and with the extra keys I can keep one in my garage, one in the shop, etc. so no time spent retrieving the key from my truck. The high visibility yellow powder coat lets folks know that my stuff is protected. Also, when parking the boat trailer in camp, I can double up security by using my pin type Master adjustable stainless latch lock as well.

Norman C.


Totally pleased. After a year of use, all 5 are working great and my equipment is nice and secure. There may be some types of tongue that these will not fit, but overall the design is nearly 100 universal. I do have one trailer, a 1946 home built tear, and these locks wont lock onto that 75 year old socket, but I just use a pin lock on that one. No complaints whatsoever. The keyed alike feature sure saves a lot of steps too.


Great customer service. Products arrived quickly and in excellent condition. Have purchased items here in the past and never disappointed.


It’s beefy and secure.


Looks great - will be put to test starting in July. Perhaps another survey then but I foresee no issues - thanks!


I bought two and it has been so nice not grabbing the wrong key since they are both keyed the same and I managed lose all my spare keys but one i was able to call and order two more. While speaking with the lady she was trying to look up my locks to find the key number having the one key just made it simpler. I had faith in her that she would be able to find my key info. I would suggest that you take a picture of your key number or write it down somewhere you will be able to remember to simplify your order


I have three locks on my trailer. This one is made great. When i first put on wouldn't go all way on so I had to hit it with palm of hand then it locked.
I will only guess because of paint is why it was difficult. But it's on and it works.


It fits perfect and looks great!


They fit great on my 2 trailers. Love one key for everything.

John L.


Works great. Bought 2 for an utility trailer and a kayak trailer. Easy to use and secure. Love the single key feature.


I really enjoy doing business with etra iler.


E trailer has quality products.

  • Will Coupler Lock Fit Atwood 8700 Coupler
    So long as your Atwood 8700 coupler uses a 1-7/8" or 2" ball, has a flat lip with a width of no more than 3-3/4" and no thicker of 5/16" then you can use the Trailer Coupler Lock # e98897.

  • Trailer Coupler Lock for a U-Haul 5x8 Enclosed Trailer
    There isn't much information on what size coupler the U-Haul trailers use. However, they state they are compatible with 1-7/8" and 2" hitch balls. So, more than likely they use 2" couplers. The 2-5/16" Coupler Lock, part # e98895, will fit on them, but there will probably be quite a bit of play. I recommend going with the smaller version, part # e98897. This one is designed to fit both 1-7/8" and 2" couplers, so it will have a more snug fit around the U-Haul coupler. I've linked to a...

  • Can Lock Core for Older Gorilla Guard Coupler Lock Be Replaced
    You might be able to have a skilled locksmith remove and change out the lock core on your older Gorilla Guard trailer coupler lock, but for your application it might just be easier to replace the entire unit since the company that makes the keys (Horizon Global) was bought out earlier this year (2023) and there's no telling when or if they will have replacement parts available. If you do choose to replace the lock then I recommend the following: - 1-7/8" or 2" Coupler # e98897 - 2-5/16"...

  • Recommended Hitch Cargo Carrier for a Honda CR-V
    I recommend going with the 20x47 Reese Cargo Carrier for 1-1/4" Hitches # 63155. This is a steel carrier with a weight rating of 300 lbs and the feature I like best about it is that there are light mounting brackets built-in so if you know your cargo is going to get in the way of your tail lights you can easily install a light kit like part # 20174. The carrier does come with a hitch pin & clip but if you'd like to add some security I recommend using the Trailer Hitch Lock # e98897 as...

  • Can the Master Lock Trailer Coupler Lock be Keyed Alike
    I have a solution but unfortunately the Master Lock Trailer Coupler Lock part # ML389DAT can not be ordered with a specific key number. Instead the etrailer Trailer Coupler Lock for Flat Lip part # e98895 can be ordered keyed alike. It doesn't work on the 1 7/8" coupler, for that use the etrailer Trailer Coupler Lock part # e98897. These are very nice quality locks that will keep your trailer secured. Check out the video I did on them that I have linked it for you.

Instead, what you'll need is a surround lock that fits over the coupler where the hitch ball attaches and is wide enough to fit your lip, which is a lock from Fastway: - Fastway Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers # FA86-0015-316 The Fastway # FA86-0015-316 fits couplers with a width up to 4-1/2 inches, comes with a pair of keys, and has...

  • How to Use the etrailer Coupler Lock for Flat Lip Couplers
    I can absolutely explain how the etrailer Trailer Coupler Lock for your flat lip coupler works, and it is extremely simple. What happens is you will slide the lock over your flat lip coupler, and push the pin up - it won't take any strength at all, you can do it with a finger. With the pin up, just turn the key and you're done; it's locked to the coupler. When you want to remove it, turn the key in the opposite direction and the pin will come down. That's literally all there is to it!...

    We have a variety of locks for your coupler, each with their own applications. If you have a fat lip coupler, I recommend the etrailer Trailer Coupler Lock - Flat Lip, part # e98897. This yellow lock can fit a 2" coupler and is an immediate deterrent as the color quickly grabs attention. The lock has a stem that reaches into the coupler and can't be wiggled free.

I am attaching a link to our selection of ball mounts that you can filter through to find one that has the correct rise/drop for your towing application (see attached helpful article).

  • Is etrailer Coupler Lock As Easy to Defeat as Curt Coupler Lock
    While the etrailer coupler lock part # e98897 and the Curt # C23086 are somewhat similar the etrailer has a different lock setup so it would not be able to be defeated in the same way. With that said I really like the Fastway coupler lock part # FA86-0015-317 as fits easier and provides the best protection that we've found.
