Use this sturdy, rustproof aluminum coupler lock with a sleek silver powder coat to help prevent trailer towaway theft. Fits standard, 2-5/16" ball couplers with flat lips. Can be keyed alike to match other etrailer locks.


A good, dependable lock! I researched all types of coupler locks, including all of the high-end locks. ALL can be compromised. This is one of the better types, with little/no spaces to insert a pry bar. I have used it for about a year now and have no regrets.

Great! Easy to use.
John M - 03/01/2022


This lock is perfect for my trailer!


Very good quality, easy to use, I would recommend this lock.

It works Great
Jack - 03/07/2022


Hands down the best coupler lock I have ever purchased. I've owned this lock for a year now and I use it everyday. Very easy to use it's and it's very solid.


Appears the quality and fit are good. Simple and functional.


Works great id it is forced on to the coupler. If not the pin will not come up. no other problems


Looks good.


Great product. Easy to use and works as advertised.


Solid product. Worth the money.


The other more expensive coupler locks slipper right off with some pressure. This one works and is a bargain.


Works great and gives me peace of mind about someone NOT being able to take my trailer.


Nice robust locking mechanism. Always on my trailer when I'm un-hitched.


Excellent item. Well made, fair price. Ordered 2 different models (2 in. and 2 5/16 in.), and they did indeed match the keys for the two different locks.


Love that I have it keyed to match my other trailer locks. Its a little bit of extra work to screw it on and off versus a traditional style lock, but its worth it. I highly recommend it.


Received lock in just a few days. Was exactly as expected. Fit my 2015 Wells Cargo enclosed trailer good.


This is a great trailer lock. It is so simplistic, light weight and perfectly constructed at the same time. I feel this will definitely deter would-be thieves.
I would recommend this to anyone looking for a NO BS, inexpensive trailer lock.


Once you have the lock on, I feel like it’s a secure lock !!
Although getting the lock on & off is not an easy task.


Second time I've ordered from etrailer and have been satisfied both times. Impressed with the selection and sale prices! Ordered on-line and received the items in 2 business days with free shipping. Lock is well-built, simple to use, and should discourage all but the most persistent theft attempts. Great place to shop!


Purchased to secure my vintage Avion travel trailer. I have invested some money and labor in it and don’t want it to disappear! The lock fits the original coupler with a little side to side play. I purchased another lock that did not fit and was pleased that this one did, as discribed. Quality appears very good.


I've dealt with Emily several times and she was always
spot on and she is the best !!!
Everything else about Etrailer is terrific !!!
Thank You !!!!


Received order quickly. Looks like this is a pretty solid way to secure my RV.


This one was recommended by Joshua from after my first lock that I ordered from was too big.
This one fit perfect.


hitch lock is very solid and easy to use very good product


It is very well made. Solid construction performs very well.


Excellent selection of multiple models to choose from on etrailer. Very satisfied with aluminum coupler lock.

  • Can the Trailer Coupler for Yakima Rack and Roll Trailers Be Locked
    Typically a coupler like the Trailer Coupler for Yakima Rack and Roll Trailers # Y08123 would be secured with a lock like the etrailer Trailer Coupler Lock # e98894. This is typically enough to deter theft. Removal of a coupler and installation of another to steal a trailer is not typically a problem. If you really wanted to secure the bolts you could use something like red Loctite. Keep in mind, you will likely have to cut the bolts off if you ever need to remove the coupler.

    We sure do! I recommend the etrailer Trailer Coupler Lock for Flat Lip 2-5/16" Ball Coupler # e87ZR if the trailer coupler has a rolled lip, or the # e98894 if the trailer coupler has a flat lip. These can be keyed alike just like you are wanting, but you will need to order all of the locks at the same time. I would see which style you need, and how many you need that way you know exactly which ones and how many of each to order. I included videos of the products for you to take a look at.

We can't look up what type of coupler any one trailer uses but I can offer you a universal trailer coupler lock that works on nearly every coupler, the Fastway Universal Trailer Coupler Lock part # DT25013KA which is a personal favorite of mine. It comes with two keys and you can order multiple with the same key if you have more than one trailer. I have...

If you're wanting to prevent the trailer from being uncoupled from a hitch, use # e98888. This lock will also prevent the trailer from being coupled, but I find the # e98894 to be more secure.

  • Locks for Use with Titan Zinc-Plated Straight-Tongue Coupler T4853100
    Yes, a coupler lock can be used on the Titan Zinc-Plated Straight-Tongue Coupler # T4853100. If you want to secure the trailer when it is not hitched, you can use the Coupler Lock # e98894 or the similar # e98895. Both of these prevent someone from hitching to your coupler. If you prefer a coupler latch lock you can use # 2847DAT from Master Lock. This type of lock works with the trailer coupled or not.

  • Recommended Coupler, Coupler Latch and Locking Hitch Pins All Keyed Alike
    I may have a solution for you, but those MasterLock trailer locks you were looking at unfortunately cannot be keyed alike, so you'd need some different options. For the coupler locks I recommend using the etrailer 2-5/16" coupler lock # e98894 or etrailer 1-7/8" or 2" coupler lock # e98893. For the latch lock I recommend using the etrailer # e98885 and for the locking hitch pins I recommend using the # e98882. You could have all of these parts keyed alike so you'd only need 1 key.

  • 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!...
