by:

I still have my trailer so I'm guessing the lock works.



by:

I have not installed the lock on the trailer yet! My trailer is available! From what I can see the lock looks very strong and easy to use! I'm sure looking forward to using the lock! It should provide excellent security!



by:

Feels solid - should work well.



by:

Bought several items in the past and they always deliver fast and accurate!



by:



by:

Great products. Very convenient to have all my trailers locked and using only one key



by:

These trailer coupler locks are great, easy to install and easy to take off. More than pleased the product and the shipping! Thanks guys, keep up the good work!



by:

I already have this lock, wanted another for my camper I think it was great I could order another with the same key code, I have 2 locks and use same key. Awesome.



by:

Works great. I park my trailer in public areas on occasion. It hasn't gotten ripped off yet!



by:

Seems sturdy. Unfortunately Fastway is one of those companies that thinks it is necessary to collect marketing information for you to complete warranty registration. Minus 1 star for that.



by:

As always, e-tailer delivers a quality product at a reasonable price with quick shipping. I like the option to purchase Coupler locks that are keyed the same.



by:

I own 3 of them, nice thing was I was able to order all 3 with the same key. Simple to use and adds sense of security.



by:

This is one serious coupler lock. If anybody manages to steal my boat they will have earned it.



by:

Best quality coupler lock on the market. Also priced fair!



by:

Ball not as big as it should be and had to shim it. Tricky to get it tight enough to stay on my trailer hitch. Very heavy duty and seems to do the job.



by:

It has proved to be an awesome trailer lock. Locking mechanism works smoothly. I purchased 1 for each of my 3 trailers and all keyed alike.



by:

Love the product I have 8 of them keyed alike nothing stolen



by:

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:

Sent key code as ordered to mstch our fleet. Thank You!



by:

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. . .



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:

quite a set up ,,hope it keeps folks from taking my trailer



by:

Locks seem heavy duty. I tried them on 4 different types of locks and found no issues with them locking. I purchased these for our whole fleet of trailers so time will tell how the hold up.



by:

This has been locking my trailer in my front yard for a year now i find where they have hit it with a hammer and it still works. good lock



by:

great fast sevice

  • Which Coupler Lock Set is Best for Use with Atwood Trailer Coupler 81911
    The Atwood Trailer Coupler 81911 that you have on your A-frame trailer can be locked in two ways, by securing the latch and by blocking entry of a hitch ball. The latch mechanism on the top can be locked with an item like the Dead Bolt # e98884. (This latch lock is one of the two locks included in part # e99039, which is our reference for the CT Johnson part RHC32.) But please note that this latch lock has a center span of only 1/2-inch; the coupler latch on your # 81911 requires a latch...

  • Keyed-Alike Trailer Coupler Locks
    WE have many coupler locks that can be ordered wit the same lock core so that one key will work on all of them. You can see all such items on the linked page, such as Fastway Universal Trailer Coupler Lock # FA86-0015-318. This fits 1-7/8-inch, 2-inch and 2-5/16-inch couplers. Once you choose your preferred lock just select the Keyed Alike option which is above the yellow Add to Cart button. There is a small upcharge for this keyed-alike option.

  • Recommended Best 2 Inch Receiver Lock for Strength and Reliability
    I think the Blue Ox Trailer Hitch Receiver Lock for 2" Hitches # BX8858 is the best and most reliable receiver lock. It has the tube key and the cover to keep dirt and grime out of the lock. Since you are obviously towing, you may also want to consider a coupler lock for your trailer. I recommend the Fastway Universal Trailer Coupler Lock # FA86-0015-318. This is the most universal fit lock and the most reliable I've found for deterring theft. It surrounds the coupler and has a tube...

  • Availability of Keyed Alike Trailer Coupler Lock
    Unfortunately, Master Lock doesn't give use the option of offering their # ML389DAT keyed alike. I'd recommend The Universal Trailer Coupler Lock, part # FA86-0015-318 which are keyed alike. This lock is offered under multiple part numbers that correspond to their key numbers. The last three digits of the part number is also the key number, the part # FA86-0015-318 comes with number 318 keys. If you want locks that have the same keys, you would order multiples of the same part number....

  • Recommended Trailer Coupler Latch Lock Keyed Alike
    I reached out to my contact at Master Lock, and the 7/8" Wide Trailer Coupler Latch Lock # 2878DAT are keyed at random and do not have the ability to be keyed alike. For a similar option you can use our etrailer.com # e98890 which can be keyed alike. Alternatively, you may be interested in the Fastway Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers # FA86-0015-318 which can also be keyed alike and add even more security.

    I do have an option for you but the Master Lock Universal Trailer Coupler Lock part # 379DAT does not have an option to come keyed alike therefore I would not be able to offer you 6 of them with the same key.

  • What Type of Coupler Does BlayLock Coupler BLTL-20 Fit
    The Blaylock Coupler Lock # BLTL-20 that you referenced is designed to fit the Bulldog Collar Lok style couplers like what you see in the picture I attached. If you are looking for a more universal style lock the Fastway part # FA86-0015-318 is very universal and effective. It also works on Collar Lok couplers as well. The second picture I attached shows this lock installed on a few of the more popular coupler designs.

    The Blaylock EZ Lock Trailer Coupler Lock for 1-7/8", 2", and 2-5/16" Couplers - Aluminum # BLTL-33 isn't necessarily designed for a tight fit. It is designed to give you a couple different pin location options but the latch is really all that keeps it in place tightly as the pin just prevents removal.

    I spoke with my contact at Master Lock about the Trailer Coupler Lock # 3784DAT. They were not certain if the lock is compatible with a 4-inch-wide coupler. But I am certain that the Fastway Universal Trailer Coupler Lock, # FA86-0015-318 Trailer Coupler Lock will work for you.

  • Can Trailer Wheel Locks be Easily Defeated
    I can pass along your lock concerns to the manufacturers. Any lock can be defeated given enough time and persistence. A wheel lock such as # RA-25 is a deterrent, as all locks are. If a thief wants that trailer bad enough, they'll find a way. Thieves have a tendency to pick the low-hanging fruit; that is to say that the mere presence of a lock is likely to cause a would-be thief to move on to an easier target. Things that take time like removing a tire from a trailer are not worth the...

  • Coupler Lock for Titan # T43329007K Brake Actuating Trailer Coupler

  • Locking Hitch Pin, Coupler Lock and Coupler Latch Lock for 3 Inch Receiver
    The span of the hitch locks included with the Reese Tow and Store lock kit don't have a span long enough to work with a 3 inch receiver. However, you could piece together a kit that'd work for you. For the receiver lock, I'd recommend the Draw-Tite # BD580412 which offers a 4 inch span and uses a high security key. For the coupler lock, use # FA86-0015-318 and for the coupler latch lock, use # 605DAT. ..

  • What Coupler Width Will the Diversi-Tech Universal Trailer Coupler Lock # FA86-0015-318 Fit
    The Diversi-Tech Universal Trailer Coupler Lock # FA86-0015-318 that you referenced can fit most couplers that are less than 4-1/2 inches in width. Most likely if your coupler is 4-1/2 wide or narrower it should work, but you can feel free to email me back with a picture of your coupler if you like. I attached a review video for this lock for you to check out as well.

If you order the part # FA86-0015-312 you get the key number 312, or the part # FA86-0015-317 you get the key number 317, and if you order the part FA86-0015-318 you get key number 318.

  • Will Master Lock Universal Trailer Coupler Lock Fit a RAM 2-5/16 Coupler
    I did a little research on RAM couplers. From what I saw, the Master Lock Universal Trailer Coupler Lock, # 379DAT, will fit the standard coupler type with a 2-5/16 inch ball size or the collar lock type that is more pointed at the end. If your coupler has a large lip around the outside where the lock would attach then it will not fit. If it does have a large lip but the width of the coupler from side to side is less than 4-1/2 inches, you could use # FA86-0015-318.

    We do have some options for you but the Master Lock Trailer Coupler Lock # ML389DAT that you referenced has a max coupler width of 3-1/4" so your coupler will be a little too big for it. For a coupler lock that can accommodate a 4" wide coupler you could use the Fastway Universal Coupler Lock - # DT25013KA or the etrailer.com Coupler Lock - # e98895. I have linked review videos for each lock so that you can get a good idea how they operate.
