I am very happy with this product. It seems to be very well made, heavy duty. Ordering was simple, and I received it quickly. It is exactly as described. 517504

So far so good, fits my 2 5/16 adjustable coupler very well. Not quite as easy to use as a Trimax (with black plastic), which has a much smoother lock engagement and release; this one takes some height adjustment before it allows you to engage the lock or remove the key, but not too bad. I mount mine backwards so that the keyhole faces the trailer - makes it harder to drill the lock. 370428

I bought two that are keyed alike, one for each of two work trailers I frequently use. The locks fit a variety of different size and shape couplers easily so it's no problem swapping them around on these and other tandem utility and camper trailers we use. A determined thief can always figure out a way to steal a trailer, but these hefty looking locks surely will discourage all but the most determined. It amazes me that with so many trailer thefts these days so few have good coupler locks installed. 23763

I have tried several locks on my equipment trailers, and none fit very well, until now. The Diversi-Tech Universal appears to be truly universal. I ordered several keyed alike so I could protect all of my trailers. I am completely happy with the product, and was pleasantly surprised at how quickly my order was shipped/delivered. I will do business with these folks again. 54969

I just put it on and can’t give a detailed review due to the fact I haven’t had time to really see how well it works. I can say it is easy to put on and seems heavy and durable. I have a 2” ball on a two horse trailer and it seems to fit although it seems like a loose fit but I think that is how it fits. It falls forward on my hitch but is secure. Some of the other trailers have locks that fit more snug and don’t wiggle, but I do think it is secure and can’t fall off. My hope is no one is going to try to break it off, bu if they do hopefully they are unsuccessful. I do wish it was more snug on my hitch. 491112

We now have a single-keyed set of very sturdy locks for our trailers. The manufacturer did a pretty good job of designing this lock. The two stops on the back side of the shackle are small pins which stick out enough to snag a finger or knuckle, but I am very happy with this lock overall. A big advantage to this lock is it is very hard to pick or pry, and we got 3 locks keyed alike - with 12 keys total, so we don't have to worry about losing a key, and don't have to carry extra keys around. The etrailer.com staff was very good to work with, and shipped quickly. 6579

I purchased a Fastway Universal Trailer Coupler lock 2 years ago. I was was very satisfied with the product. Like all locks out in the weather, you need to just keep them sprayed up with a good lubricant. I purchased three more keyed alike for my other trailers. Kelly at etrailer was very helpful with my order. I made other purchases with eTrailer and always satisfied with their products, service and fast shipping. I also like the videos of their products and installation. 437062

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 428280

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! 483796

Unfortunatley this lock didn't last a week. locked it to my trailer, and somehow the internal female end turned after trailering and could not get key to insert, thus it wouldn't unlock. the other problem is it only took a swift swing of a normal size hammer to break it free. I never called or wrote for a replacement or refund. I'm just doing a follow up that was asked of me. 545540

Key can be bent with rough handling. etrailer: consider beefing up the junction between the key shaft and handle for the next design iteration. Looks like if it were to break, pliers would make the key work until a replacement is ordered. Overall functions well: fits secure and looks good. Go easy on the key. 559780


Comments

Were a distributor, not a manufacturer but I will certainly pass your comments along to Fastway. I can tell you that with the years of experience Ive had dealing with barrel-style locks is that it is very important to be gentle with the keys. Its imperative that you use the mud-and-crud plug to keep moisture and debris out of the lock. Youll also want to regularly lubricate the lock using air tool oil. If you use the key, and its not wanting to turn easily, use the oil, then give the end of the key a sharp rap with a mallet. This will free up the tumblers allowing you to turn the lock mechanism.

First trip out with this item and it malfunctioned. And I mean the very first time locking. It uses a round key. The lock allowed my key to be removed in the wrong position. When it was time to leave, the key would not go back into the keyhole. I had no choice but to cut it off. Fortunately, I brought my Sawzall for cutting firewood. With the metal blade I cut it off in 45 seconds. Etrailer gave me the phone number to the factory. I told the factory what happened. They asked "if the keyhole was stuck in the 2 o'clock position?" I said yes. So I'd say I wasn't the first guy with this dilemma. They sent me a new one for free within 2 weeks. 510242

Very easy product to install on my boat trailer. I always want that extra security of not having someone just hook up to my trailer and this product fits that perfectly. The quality if excellent and the ease of installation is great. I like how easy it is to install and remove which takes a few seconds. Just what you need to secure a trailer quickly and with a better mouse trap than a typical pin type of lock, 327701

Just received product today due to delays at the mfg not of eTrailers doing. They did an excellent job of keeping me advised of the status of my order. I installed the lock and it looks like it will work very well. It appears to be well constructed and heavy enough to act as a theft deterrent. All any of these trailer locks can do is make stealing the trailer too difficult and too time consuming so the thieves move on in search of easier pickings. Only time will tell how the lock holds up to use and to the elements. 264281

Great product - this was my third attempt to find a coupler lock that would fit. The other two claimed to fit 99% but not mine, The Max Security Universal was the first one that did. Great quality - outstanding communication that started right after I ordered. Highly recommend for coupler lock as well as etrailer. I will be a repeat customer. 11875

it looks like it would work, however I'm a little concerned with the "fit". It seems a little lose over tongue and a good 5lb. hammer could knock it off?? Hopefully that will never happen. 544829

I ordered 6 of these, all keyed alike, and they are working great. They are built very strong and anyone attempting to steal one of my trailers is going to have to work a little and spend a lot of precious time getting this thing off. 570857

Lock mechanism is prone to issues. Key got jammed and had to cut lock off of trailer. Took 15 seconds with an angle grinder. Not as secure as it looks. 437283

Products arrived quickly and exactly what I ordered. 2 trailer hitch locks keyed the same. Expect a spam email follow up after every order delivery asking you to come back to their site and leave feedback....ect. The request is worded more along the lines of "tell us how great we are", instead of actual concern if there may be any issues with your current order that they want to know about and immediately remedy. 419449

This is really a very nice product. I store a very nice trailer and wanted to protect it from theft. I found many of these type locks but they had weaknesses. This trailer lock does not rust or corrode. It also resists attempts to break it with a large hammer. Personally, I think it is like buying insurance. After a year's use, I have had absolutely no problems. If I had to do this again, I would buy this well made trailer hitch lock. 338556

I bought 5 of them for our trailers and we are using zero. They’re junk. The key gets hole somehow gets stuck at a 2 o’clock position making it impossible to get the key in as another reviewer had said. The chroming also flakes off and the particulates get in the keyhole also. I asked for a refund but I had to send them back on my dime. You can cut these off like butter with a cordless grinder as we had to because they got stuck on the trailer. 623179
