Video Transcript for Fastway Universal Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers Review
Today we're going to be taking a look at the Fastway Universal Coupler Lock. The universal design is going to protect most trailers from being towed away, so it's designed to provide maximum security for your unattended trailer. That's going to protect it from theft. It's going to use a multi-step uni-ball that fits into any size ball coupler. Now, this piece is a solid construction. It's not hollow like similar designs and models. The shackle has a really nice unique bend.
This is a reversible design that allows it to snug up tight to most type of couplers or coupler latches, including all the ones that you see here on the table, such as A-frame, straight channel, round tongue, flat plate, and surge-type couplers. It's also going to accommodate a variety of latching mechanisms, such as trigger, pin, thumb, and wrap-around yoke latches. It works great on all the ones that you see here on the table. Really nice, universal design that's going to provide maximum security to your unattended trailer. The unit features a tube key lock cylinder that provides better security than standard key mechanisms. It's a lot harder to pick, and it's more difficult to duplicate keys. It's also going to feature an anti-drill pin that discourages attempts to drill out the lock. The unit's also going to feature bolt-blocked locking system to prevent thieves from prying the lock open.
Inside this hole right there, there's going to be a small bolt that engages the shackle. Right now it'd be in the unlock position. You can see how that comes out just a little bit. It doesn't take much to secure the unit. That bolt that runs through there engages the drews 00:01:42 on the shackle to keep it from being pried off of the trailer coupler. Now, when it comes to the construction, we're looking at a hardened steel construction.
When it comes to the shackle, it's going to provide maximum cut-resistance. Chrome-plated finish does a great job at resisting rusting corrosion. Then we're looking at a solid dye-cast corrosion-resistant housing that's very strong and very durable. Two keys are included per lock. They are numbered. The keys are going to be unique to the universal lock that you choose.
This is going to fit 1 and 7/8 inch, 2 inch, and 2 and 5/16 inch ball couplers. You just need to make sure that the coupler width does not exceed 4 and 1/2 inches. The shackle diameter is 5/8 of an inch, and the unit's going to be covered with a limited lifetime warranty. I just want to show you how it installs and how easy it is to use. What you'll need to do is separate the 2 components, so just move it to the unlock position. It also has a nice dust cap that protects that lock opening. It's going to a great job at keeping out dirt and moisture. When you're ready to use it, all you need to do is make sure that the coupler is in the open position. Ball portion goes in there. Then, all you got to do it secure it, just as if you're hooking it up to your hitch ball. Then, install the shackle. You need to determine which way is going to work best for your application. For this one, I just want to make sure that the point is pointing back towards the trailer. It is a universal design, that way you can adjust it however you need to use the lock to fit your application the best. Then, we just move it to an unlocked position. Allow that shackle to go down as far as possible. Move the key to the locked position, and it removes from the core. Place on the dust cap, and that's on there. It's not going to come off. The only way to get it off is to use 1 of the 2 keys to unlock the unit. That's going to do it for today's look. The Fastway Universal Coupler Lock.

good product. Been using these for years. We have 12 bumper pull style trailers and use these tongue locks when they are on job sites. It's nice from e trailer because we can get the locks keyed the same. It was miserable having a bunch of different keys.

The ball lock I purchased from etrailer.com is the perfect tool for the job. It has several locking positions for different height tongue assemblies and one which was perfect for mine. The lock is smaller than the one I replaced, rendering it much less obtrusive. The chrome coloring also helps it blend better with the hitch, so if you use it while camping your trailer has a “friendlier” appearance to fellow campers. I really like the fact it came with 4 keys and case hardening makes it even safer and lighter than my old lock. Best of all, however, was the superb customer service I received from etrailer.com. Before, during, and yes, even after I received my lock they followed up to make sure I was happy. 5 star service. Would definitely recommend them to my trailering friends.

What an unexpected pleasure to open my e-mail and find a follow up message from you a year after I purchased from you.I hope things are going well for both you and etrailer.com. Even though I have not had the need to purchase any additional parts for my trailer in the intervening year, I continue to recommend your company to those of my friends who are still restoring their trailers. I hope many of them have used your company for their parts orders and are as happy as I have been with your stellar service and great products. Ive attached a few photos for you of my current set up. One shows the ball lock in place so if others wish to know what it would look like installed you may share it with them feel free to edit out my chickens, she says with a laugh. The PDF file is a copy of the front page of our local newspaper when my trailer made the Christmas day cover. And the last photo was taken in October at Lake Skinner just to prove that my baby is not a trailer queen we actually go camping on a quite regular basis we went out 8 times last year. Ok, having shared my baby pictures with you, I would also like to tell you a somewhat sad tale. I have a fellow Sister-On-The-Fly all female camping group, who 2 months ago had her trailer stolen...right out of her driveway at her home. She was devastated to say the least. She put this sad news out on the vintage e-mail websites and, fortunately for her, the vintage trailer community leapt into action and she began receiving steady e-mails about the progress of her stolen trailer from those who spotted it along the way. Enough e-mails in fact that the local law enforcement was able to follow them and was able to recover her trailer, amazingly enough. I ran into her at a recent trailer gathering and found out she did not have a ball lock on it when it was taken, and Ive made it part of my discussions with the ladies on our trips to mention the necessity of locking your trailer, both in your driveway and on trips we had another one taken, boldly during daylight, at a vintage rally!. I show them how the lock works and recommend they contact etrailer.com for one. They like mine because it is much less industrial looking and that matters to the ladies.Well to keep this from becoming a novel, I suppose I should sign off and let you get back to business, Patrick. Thank you again for checking in, that was truly amazing. Ill continue to recommend you and etrailer.com and when I next need parts and vintage trailers always do, be assured I will contact you first.Have a great day, and thank you for helping to keep my Aunt Bea safe and where she belongs.Best regards,Maggie

My trailer has a wide flange around the coupler and the stepped design of the bail fits perfectly. The circular keyway is secure and the casting is smooth. The teeth on both sides of the bail provide more secure latching than my one-sided prior lock. The main lock piece is smooth on the bottom preventing someone from hooking under the lock and just towing the trailer away. My prior lock had a lip that allowed the trailer to be moved with a tow hook.
My only complaint is that it came with two very sharp, very pointy metal pins sticking out of the bail, maybe to secure it in the package. I had to get a pair of pliers to remove these before they ripped my hands up.

I noted the same problem with the sharp clevis ? pins protruding from the bail. They do not seem to serve any purpose and there is no information in the instruction sheet that would indicate removal of the pins would somehow diminish the security of the lock. At first I assumed they prevented the shackle from being pushed too far into the lock but that was not the case. Mine are coming out and if it violates the warranty at least I wont have ripped my fingers and hands open.

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. . .

Fits my trailer and ordered one with same key as the one on my other trailer which is very handy. I suppose, with enough effort, this lock could be defeated but it presents a good reason to just move on to an unprotected trailer.

See what our Experts say about this Fastway Trailer Tongue Lock
- Surround Coupler Similar to Reese Tow Power 7088300 that Can be Keyed AlikeWe have a very similar setup that can be keyed alike with the Fastway Universal Coupler Lock part # FA86-0015-305 which uses the same key of 305 that you could order as many as you'd like with the same key. The Reese Tow Power lock you mentioned is one that we don't carry but it can't be keyed alike so the Fastway would be your best option.
view full answer... - Recommended Coupler Lock That Can Be Keyed AlikeI do have a great option for you, however the Blu Ox Trailer Coupler Lock # BX88351 that you referenced cannot be keyed alike with other units. If you were to order 7 of these locks you may get 7 different lock cores/keys. For a similar coupler lock that can be ordered keyed alike I highly recommend the Fastway Universal Trailer Coupler Lock # FA86-0015-316, which like the Bulldog model will fit 1-7/8", 2", and 2-5/16" hitch balls. It features an anti-drill pin that discourages drilling...
view full answer... - Recommendation for Most Secure Trailer Coupler LockThe more secure coupler locks we offer are designed for be used when the trailer isn't hitched to the vehicle. They're designed to prevent the coupler from being hitched to a trailer ball, like # FA86-0015-305. With the trailer attached to the ball, you'd want to use something that would prevent the latch mechanism of the coupler from being opened, as well as securing the ball mount into the hitch receiver using something like the # BD580402 hitch lock you'd looked at. The latch locks...

The Fastway Universal Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers - Key 305 # FA86-0015-305 is what you're looking for. This will match the other locks and keys you have ordered from us in the past. What kind of trailer do you have?
