Use this sturdy, rustproof aluminum coupler lock with high-visibility yellow color to help prevent trailer towaway theft. Fits trigger-style, 1-7/8" and 2" ball couplers with flat lips. Can be keyed alike to match other etrailer locks.


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.
MJ-TX - 11/17/2022


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.

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?
-- Etrailer Expert Jenny N - 04/05/2022


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.

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.
NORMAN H - 12/10/2021


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


After a mix up about the keys, everything was corrected & this lock is great. I like the yellow color, so people don't walk into it if the trailer is on the ground.


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

Works great. Bought 2 for an utility trailer and a kayak trailer. Easy to use and secure. Love the single key feature.
John L - 04/30/2022


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


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


After having a $1,500 utility trailer stolen via cut Master lock, I upgraded to this lock! Try to get this one off!
Works well and fits very good on Shorelander boat trailer!
Installed on my boat trailer with 2 inch flat tongue ball


I shipped back the two smaller ones but never received the larger ones

We ped the ball on that David! I sent your information over to customer service to take care of it.

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.


Looks well made. I would recommend.


Fits good and looks good hevy metal good lock.


Excellent customer service!! I would recommend them to everyone!


Like all your products it’s excellent!


Quick shipping, good communication, great product


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.


Same as my above review


This is the best so far. Fits perfect. Tight fit


It was snug, maybe a little too snug... had to sort of force it on in order to get the pin up. I would still rather have snug rather than loose.


Easy to install/remove. I do wish it was there was an option made of a different material. maybe a stainless steel? I think the aluminum could be overcome with a few good blows from a hand sledge. Love the fact that most products have videos. Very helpful in choosing the correct product.


The lock works great even a child can put it on or remove it


Another level of security and easy to u se.


Fast shipping as advertised great customer service


I have yet to use it on a trip or in storage. I use it on a 2" coupler. Fits very good and should send a thief to another trailer.

  • 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 etrailer Coupler Lock and 5th Wheel Lock be Keyed Alike
    Yes since both of the locks are etrailer brand locks with keyed alike options you can key the part # e98896 and # e98897 together.

  • Difference Between etrailer Trailer Coupler Lock e98897 And e98893
    The etrailer Trailer Coupler Lock - Flat Lip 1-7/8" and 2" Ball Couplers - Aluminum - Yellow # e98897 and the etrailer Trailer Coupler Lock for Flat Lip 1-7/8" and 2" Ball Couplers - Aluminum - Silver # e98893 is the exact same part, the only difference is what color they are powder coated.

  • 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...

  • Trailer Coupler Lock For 4-1/4 Inch Wide Coupler Lip
    We have a lock that will work for you, though the # e98897 won't work with a coupler that has a maximum of 4-1/4 width. 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 # DT25013KA The Fastway # DT25013KA fits couplers with a width up to 4-1/2 inches, comes with a pair of keys, and has an anti-drill...

  • 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!...

  • 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.

  • Comparing Different Types of Coupler Locks
    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. If you don't have a fat lip coupler but still want a lock that reaches into the coupler, I recommend the EZ Lock Trailer Coupler...

  • What Will Prevent Movement/Noise in 1-1/4 inch Hitch
    Sounds like what you are looking for is a hitch anti-rattle system. This will eliminate the movement between the hitch opening and your ball mount which will then stop the noise you are hearing. With two products, we can get this done. We have the part # e98997 for a hitch lock but would only work if your ball mount has a hollow shank. Then add the Roadmaster Quiet Hitch part # RM-061-125 will remove the rattle regardless of if the shank is hollow or solid but does not feature a lock....

  • 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 # DT25013KA as fits easier and provides the best protection that we've found.

  • Can the PortablePET Twistep # HE305 be Permanently Installed on Dual Trailer Hitch Adapter
    Yes, you can use a multipurpose ball mount, like the Curt # D210, to tow a trailer weekly and keep the PortablePET Twistep Hitch Mounted Step # HE3052 permanently installed. 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). Keep in mind that some adapters will reduce the Tongue Weight (TW) of your trailer hitch by 50%. The ones that do this have a note...

  • Can the Reese Tow and Store Lock Kit Be Keyed Alike
    The Reese Tow and Store Lock Kit part # RP7014700 does not have a keyed alike option so there would be no way to obtain multiple kits with the same key unfortunately. However, you could combine any of the locks and they would all come keyed alike so long as you select that option on the product page. I have attached a list of these options for you below.

  • Recommended Cargo Carriers Popular With A 2012 Honda CR-V
    For your 2012 Honda CR-V, there are two different trailer hitch receiver sizes, so a couple different popular options due to that. For a 1-1/4 inch hitch receiver, the most popular is the 17x46 Curt Cargo Carrier for 1-1/4" Hitches lbs # C18145. This carrier has a straight shank for greater ground clearance, but it does not have a folding feature. The sides and the metal floor provide many attachment points for tie down straps like # EM04418 or the Cargo Net 36" x 48" # CS54FR. I recommend...
