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.

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.

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...

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

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!!!

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:

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.

A year later and nobody has stolen my trailers so... They work great

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

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.



- DT25013KA
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:

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

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.

Can be a little tricky to get it as tight as I need it on my trailer, but overall a really good product. I bought a second one for my towable smoker.

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.

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.



- DT25013KA

The unit works as needed, I haven't had anyone try to break it off, but it appears to be made of good quality.

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.

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!

I had a hard time finding a tongue lock to fit my Jayco with an underslung coupler, this fits perfectly.



- DT25013KA
by:

I wanted to get a good quality lock for my new trailer and looked at several different videos showing plus or minuses of this type of lock. I wanted a good quality unit which would not break the bank. etrailer came through. I am pleased with my purchase and already have it installed.


Comments
The lock is still going strong and has held up well. Lubricate it regularly since it is out in the weather but overall a good product

Perfect for those of us that own multiple trailers and multiple trucks with multiple employees. Highly recommend.



- DT25013KA
by:

This is the only tongue lock that I have found that will fit my trailer. It appears to be well made.



- DT25013KA
by:

The only reason I did not give it 5 stars is the key number. I needed a particular key number and even though you could select “keyed alike” there was no place to enter the key number. I had to contact etrailer to get the correct key on the order.


Comments
Thank you for your review. Our Customer Service team reaches out about the key number or you can reach out if you do not want to wait for their call or email.

    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...

  • Recommended Coupler Lock for 3 Inch Wide Coupler
    I do have a solution for you, however we do not currently have a pin lock for your coupler that features a 3/8 inch diameter pin. I recommend looking at a different style lock such as the Fastway Universal Trailer Coupler Lock # DT25013KA. This universal design will fit into any size ball coupler by using a ball and shackle to fit inside the coupler. It will work with 1-7/8 inch, 2 inch and 2-5/16 inch ball couplers. It will fit also coupler widths up to 4-1/2 inches. The unit is made...

    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...
