Fastway Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers - DT25013KA

Average Customer Rating:  4.7 out of 5 stars   (818 Customer Reviews)

Protect almost any trailer from theft with this universal coupler lock. Uses a unique "ball" and shackle to fit a variety of coupler sizes and styles. Secures trailer when it is not in tow. Can be keyed alike to match other Fastway locks.

I bought several of these, keyed alike and have found them useful. The keyed alike feature is a winner. One key on every set of vehicle keys and I can access any of the rigs at will. The product itself can be a bit tricky to align, and on a steel hitch it will take some of the paint off eventually. Better than getting stolen I'd say. I've used it on 2 inch, 2&5/16 50mm and 1&7/8 couplers. The best fit is on the hitch I show a picture of, though in this case the lock is probably worth more than the trailer. . .

I think the Fastway Trailer Coupler lock is one of the best Toy Hauler locks on the market. It's a solid well constructed tough product, and reasonably priced...it gives you an extra edge of securing your Toy Hauler when your out of town at Car Shows/Cruis'ens and you can even reverse it on certain makes of trailers depending on how the trailer tongue/coupler is constructed/designed which makes the key slot even more difficult to get at. etrailer is one of the best companies to do business that I have run across in a long time. There Customers Service Reps are excellent well trained individuals that have good customer service manners and follow ups...keep doing what you do best. Your on the same playing field as [racing company] and a couple of other businesses that have excellent customer service reputations...


Comments
The review that I sent to you in 2021 still stands in 2022. The fastway Coupler Lock I ordered from etrailer is in use 248. I have had zero issues with the locks functioning as it should. With a shot or two of lithium grease every now and then it continues to do what it was designed to do. Great price,design and workmanship...

We’ve had the hardest time locating a coupler lock wide enough for our camper hatch. This one fits perfectly. Quick shipping.




by:

I'm so happy with this lock. I don't have to be concerned that someone will try to steal my trailer
It is easy to put on and take off. As the description says, you may think it isn't secure but there is no reasonable way to get it off without the key.


Comments
Have to admit I dont use this as much as I thought I would. Its just a little annoying to put on and take off.
Linda - 12/07/2022


by:

They seem solid and the fit all three trailers well, and I like that they are keyed alike. I wish they fit a little more snuggly, but there can only be so much adjustment.




by:

I have had this lock for a year now, no issues whatsoever. I especially like the cover for the key hole, keeping dirt and debris out.

We’ve been using this coupler lock on our little camper for about a year. It’s easy to use, and we can rest a bit easier knowing our camper is protected.




by:

They work great, I ended up buying 10 of them to have one on each of my trailers (with balls of all sizes). Simple and all keyed the same. Will they keep a diehard thief from stealing one of them? Probably not but will they keep the average idiot away... I think so.




by:

Have a 10 ft Tex trailer, my son came over and hit it hard, it slipped over the ball latch, you could lift up the latch, taking it off. So we welded a piece of metal on the latch so it will not slip off now. Works great and heavily built




by:

Works great to lock your trailer coupler. Have 2 of them for my 2 trailers.




by:

Wanted a set of trailer locks keyed for both my trailers. etrailer hooked me up. The locks are heavy duty and work as expected. Thanks etrailer!




by:

I was a little disappointed in the lock. The shackle is very robust and I'm sure very strong but the body of the lock, I'm not so sure. It feels very light weight. It is not magnetic so it's not steel. It appears to be cast aluminum or diecast. It seems like one good wack with a hammer would break it but maybe not, maybe it's stronger than I think. It does fit very nice and tight on my coupler and the only way a thief would get it off would be to
break it or cut it. I would buy it again if I needed one for another trailer.




by:

when I found this lock online your web site said "Made in USA". When I spent my money to purchase it and recieved it, Just as I suspected, the packaging said "designed in USA, made in taiwan" Very deceptive! I want a full refund and a return shipping label.


Comments
This lock is not made in the USA. I checked and for this style of lock I do not have one to offer that is made in the US.

I just purchased several items from etrailer. See photo for trailer lock and a new set of chains. I keep my trailer on the street and thought I had better start securing a little better. This hitch lock installed easily enough. I purchased three of them keyed alike for three different trailers, work trailer, camping trailer, and utility trailer. Super easy. This is my third purchase from etrailer over the years, and the customer support is out of this world. Actual people who call and email to follow up. etrailer sets the standard for what customer support should be.




by:

Excellent product, fits the coupler on my Airstream trailer perfectly, very heavy strong secure lock.


Comments
Works perfectly!

Great product & great service. We ordered this lock for our 2018 Jayco Jay Feather travel trailer. After buying and returning similar locks at our local camper and automotive stores that did not fit, we turned to the internet and found etrailer.com. The website made it easy to shop. It showed the dimensions for this lock. We knew it would fit when we received it. We are extremely satisfied with the service and product we received. Thanks, etrailer!




by:

Perfect fit for my older 1990's 26ft sailboat trailer - Solid lock - Easy to use - Nice addition to the "Tow Ready - Butterfly Lock" I also purchased from etrailer.com for the latch - Peace of mind is everything - 5 Stars on both locks




by:

I have two of these locks in use and I recommend them highly. incredibly durable and easy to use.




by:

Ashley was a great help and made my order very easy. The locks were delivered very quickly.




by:

The Fastway lock gets only three stars based on the slop in the lock left once you ratchet u-lock into the base. It is a concern that a theft could pry it over ball coupler. etrailer customer service and prompted shipping was 5 star. etrailer as a distributor of Fastway, please pass this review on.




by:

Great hitch lock - haven't had a generator stolen yet with one of these deployed on the hitch. Downside is that the finish isn't Chrome - it's a mylar film that will peel off, and can cut you (personal experience)


Comments
Weve had no generators that have been secured with this tongue lock. Great hardware!!!
Aaron M - 10/29/2021


by:

I ordered two of these locks keyed for both of my new trailers E TRAILER. ROCKS


Comments
great never had any problems with them
Charlie - 05/31/2019


by:

I think this is the best bang for you buck. Nice beefy lock. I was able to buy multiple locks for 3 trailers all keyed the same. It fits skinny or wide tongue configurations. Im in a cold winter climate, they will freeze up, but that is with any lock that you buy. Keep a little handy torch in the trailer to warm it up, takes only a minute. Ive had these for a little over a year with no problems.


Comments
A year later and nobody has stolen my trailers so... They work great
Jacob H - 07/30/2021


by:

Easy to order
Arrived promptly and product
is what I expected
Bit on the pricey side ...


Comments
Trailer lock is still working fine after a year …
Dale - 08/28/2022


by:

The lock is well made but fits loosely in the 2 5/16” coupler. The “ball” part of the lock is too small for the space it occupies. I’ll probably modify it.


Comments
I’m still using the lock and it still works well. I’ve noticed most trailer campers use them when they unhook at campgrounds.

  • Coupler Lock Recommendation that Can Be Keyed Alike
    The Steal Shield A-Frame Trailer Coupler Lock # SS05110 that you referenced can't be keyed alike unfortunately. We do have several coupler locks that can be keyed alike though. I attached a link that will show you all of them. The most popular one we carry though is the Fastway Universal Trailer Coupler Lock # DT25013KA. I attached a review video for you to check out.

    A combination coupler lock would be a great idea, but we don't carry anything like that at this time. I do have one solution for you to consider that I can help you with. You could get the Fastway Universal Trailer Coupler Lock # DT25013KA. This lock can be keyed alike so you could order all 6 of the ones you need and they will all come with the same lock core and matching set of keys.

  • Coupler Lock Recommendation for a 8 foot Haulmark Trailer
    Without knowing what style of coupler you have on your 8 foot Haulmark trailer it's hard for me to say exactly what would be the best coupler lock to use. I can say that the Fastway Universal Trailer Coupler Lock # DT25013KA is a great lock that can fit nearly almost all styles of couplers and has a ton of positive reviews from our customers who have tried it. It also fits all of the standard hitch ball sizes. I attached a review video for you to check out as well.

    I walked out to our warehouse and pulled the Tow Ready Trailer Coupler Lock. The locking bar measures approximately a 1/2 inch in diameter.

  • Does Fastway Universal Trailer Coupler Lock Use a Spring Loaded Lock
    I reached out to my contact at Fastway who said that there are springs behind the tumblers that push them back in place on the Fastway Universal Trailer Coupler Lock # DT25013KA. I'm not sure if that's what you mean by spring loaded or not though. I pulled the part from our warehouse and found that the shackle doesn't ratchet down into the locking mechanism. You will need to keep the key in the unlocked position until the shackle is at the desired location. The parts that extend out and...

  • Best Surround Style Trailer Coupler Lock for Square Coupler Head
    The best surround style trailer coupler lock we offer for the square style trailer couplers is the Fastway Universal Trailer Coupler Lock part # DT25013KA because of the long u-bolt which will accommodate a much taller coupler head like those on the square style. I don't have any other better options from Baylock unfortunately.

  • Recommended Coupler Lock for Trailer with 2 Coupler
    The Fastway Universal Trailer Coupler Lock part # DT25013KA is my recommendation for a trailer coupler lock that will be used to protect the trailer while not in use and detached from the tow vehicle. This coupler lock is universal so it will work with pretty much any trailer. The anti-drill pin helps further prevent the lock core from being drilling and the hardened shackles help further prevent the chance of it being able to be cut.

Just click on the Keyed Alike menu tool and enter your total quantity, in your case 3 of item # DT25013KA. You'll receive three coupler locks that will all function from the same keys.

  • What Does Keyed Alike Mean for Fastway Universal Trailer Coupler Lock # DT25013KA
    We can key alike different locks by the same manufacturer but not from different brands as they use totally different locks/keys. So if you ordered more than one of the Fastway Universal Trailer Coupler Lock # DT25013KA and you selected keyed alike you'd get more than one that use the same key.
