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




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 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:

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:

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.

by:

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:

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


Comments
Works perfectly!
Joe Q - 10/02/2017



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:

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:

very strong and sturdy BUT has two small problems the reason for not giving 4-5 stars
they have to be removed and oiled every three months if you don't you will have hell of a time unlocking them, at first you think the key is not working and then you think that the lock has jammed to aid in this aggravation the lock will not release unless you keep key turned ( not spring loaded, they saved money by not adding this feature)(mistake)a a bit hard to hit hitch with hammer and keep key turned and not break key also tolerance is way to tight which of course leads to main reason for it seizing up.
Fix the key and a little most tolerance or do not use it for long term storage. yes I kept the lock clean of dirt and debris.


Comments
it works great but would have liked some information on maintenance WD40 or 3in1 oil or Masterblaster and and where to put it in the lock or the pins that lock it had some problem with them locking up if they sat to long with out being opened or closed have five trailers 3 of them can set for months be for i use them BUT the good news nobody has even made an attempt to steal them like i said good stuff well built i trim trees for a living i get robbed more than the bank

Works well on various hitches and gives high degree of security.




by:

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...

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:

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 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:

Wouldn't leave home without it. Secures trailer nicely.




by:

Very heavy duty! Very satisfied.




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.
Robert - 08/29/2021


by:

Ordered these for all of our enclosed trailers, equipment trailer, and dump trailer. They all fit snug and are keyed alike as requested. SO far, I would recommend this for sure!




by:

For the money these coupler locks are a great deal. Its also a big advantage having them all keyed alike for our fleet of trailers.




by:

Great experience, Very helpful keyed locks alike for a reasonable cost. Superfast free shipping, and better locks than I could have imagined. Thanks.




by:

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:

Great product! This is a repeat buy for us! We have one for our small horse trailer and liked it so much we bought another! Great customer service!




by:

Exactly as described and does the job! It’s very sturdy and rugged - does not feel cheap.




by:

Nicely built. Easy to use!

  • Recommend Trailer Coupler Lock That Will Help Deter Theft
    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. The representative at Tow Ready informed me that the lock is made of 1407 steel. I then contacted our representative at Fastway about the Universal Trailer Coupler Lock, part # DT25013KA. He informed me that this locking bar has a diameter of 5/8 inch hardened steel. He informed me that this is the biggest and strongest lock on the market and is not...

  • Solution for Preventing Trailer Theft When Away From Trailer
    For your dump trailer, I recommend looking into an alternate theft prevention method while it is unattended. Since a trailer breakaway kit needs to be powered by a fully charged battery, the issue you described in your question of coming back to a depleted battery will persist, regardless of how the kit is connected. Most likely the battery for your breakaway kit is actually depleted long before you return to the trailer if it is sitting for a few days. This essentially means that...
