This steel lock mechanism will only keep an honest person away. I hit the lock with a hammer and it cracked off, rendering it useless. The key loxk has to be spun on, so if you keep the rubber protector in place its a pain to screw on with the key inserted. Get a reL trailer lock that goes in the ball mechanism. Do not wastevyoyr money on this styleock it is useless against and criminal intetent.

Perfect for the Demco EzLatch on my utility trailer. Very easy to use and provides the security for my trailer that I sought.

Works very well, and as intended. Adds a sense of real security & safety.

Great product! I bought this coupler lock to replace others that kept bending while pulling my boat. After a year and fishing about once a week, pulling over mountains, and having to hit the brakes hard a couple of times, this coupler has held up superbly! etrailer is my go to place for all trailer products, great selection of products, super description of their products, often with video link, fantastic service and very competitive prices!


Comments
Super! Works as good today as the day I receivedit!
Edward M - 03/06/2022

by:

Perfect for the newer Demco coupler. I had been looking for a way to secure the coupler and this worked perfectly. The bonus was being able to have it keyed the same as 2 smaller locks for other trailers.



- e98888
by:

A little longer than what I was expecting and the process of unlocking is a bit tedious. You have to keeping spinning around unscrewing the lock from threads.



- e98888
by:

Good value since the coupler lock works exactly as intended. Best part - even tho outside year around in Seattle weather, no corrosion since chrome plating more than adequate. Works on both electric and surge brake couplers with thru-body locks requiring extra length (span).



- e98888
by:

I have broken 2 locking coupler locking pins due to tongue moving forward with surge brakes. This product is not an ideal solution as you need to spin on and off with the key to lock and unlock the pin. Turning a key 10-15 times to screw in and out is a pain. This will be a back up at best to some other solution I am still seeking.


Comments
You may like this product better as it is just one turn of a barrel key which makes it a little easier: Item # MT76FR

Just installed on trailer. Looks to be well made. Fit like a glove and keys worked well. We will see how well it holds up, my guess I think it will be fine.

Still going strong, no problems !!!!
Raymond - 04/17/2022

by:

I was sent a follow up email asking how I liked the lock, and I have to say that I liked it enough to buy it a second time after I LOST THE KEYS!!! Because losing keys in my job!!! But yes it is a great lock for my trailer, because it has an odd coupler that a pin goes completely through it and you can’t use a standard padlock or coupler lock. The coupler locks sold at local stores were not long enough to go through the coupler, so I has to search the internet and I found this at trailer.com and it works! I would definitely recommend this lock if you have this style of coupler.



- e98888
by:

These seem to be made well. Yet to be seen how they hold up over time. Having several trailers, the keyed alike feature was important to me and I was able to order the lengths I needed for the various coupler types. I saw some reviews indicating that the operation of these was slow or tedious. I found that insert the key, hold the key and spin the black end was simple and quick.



- e98888
by:

I love it. Works perfectly. Though at times, I just wish I could shorten the length.


Comments
Its still right where I use it, working perfectly.

A great locking system. I've tried many different ones before and this is the best I've found. Also reasonably priced and quality built.

This product is awesome. Would only buy this one when I need another lock for another trailer.

Great solution for the RV and getting it keyed the same as the Hitch Receiver was nice.

PURCHASED A TRAILER LOCK, IT FIT PERFECTLY. VERY HAPPY WITH THE PURCHASE



- e98888
by:

Worked perfect! After buying multiple locks and having them be too short, this one worked perfect. Always love etrailers customer service and prices. You can’t go wrong!



- e98888
by:

Bought multiple receiver locks and hitch locks, all keyed the same. Incredibly convenient to always use the same key no matter what vehicle or trailer you are using.



- e98888
by:

As advertised, works perfectly with my 2" DemcoEZ coupler.



- e98888
by:

I bought this coupler lock, because my hitch was too wide for a standard coupler to work. It works fine and looks great. It is a pain to have to keep turning the key around and around to "unlock" the device from the hitch. From a theft or security perspective, it is awesome.



- e98888
by:

I just got off the phone with costumer service. The coupler just arrived with no key and no locking mechanism. Just the bar with the two ends. The end that is supposed to include the lock is hollow. I received the new item to replace the defective one and the new was is complete.



- e98888
by:

I was a bit disappointed when my new lock arrived and I found out that this lock has a "screw on-screw off" locking mechanism. It also feels like it sticks and isn't smooth like a Master Lock or higher quality lock. I use this on a trailer that is around salt water so I am interested to see how long it works. Only time will tell.



- e98888
by:

Will buy it again! No second guessing if stock pin is secure or felt! Easy to install



- e98888
by:

This is the best product of its kind that I've found. The 1st one that I purchased 5 years ago served me well until I trailered an entire day before realizing that I had forgotten to lock it in place, leaving it on the tongue of my boat trailer. I particularly like this design because it can be "turned in"/ tightened until flush with the receiver, with no play whatsoever unlike some other designs that simply snap in place like a standard padlock and have sloppy play. I believe that locks are for the most part simply a deterrent to theft, not preventative. This design is attractive, very functional and reasonably priced. Ordered a pair of them for my daughter's family boat as well as my own.



- e98888
by:

As described, perfect fit and looks good. Quick ship as well. Thank you etrailer.com!!



- e98888
by:

Exactly what I needed to lock my 2 trailers. Keyed alike locks for ease of use. 1 key that’s all. Thanks



- e98888
by:

This product was sold to me to work with the 2 5/16” ball coupler, that I purchased at the same time. The shaft of this lock is smaller than the hole in the coupler, by a great margin. The lock fit in the coupler is sloppy, and could be cut off easily because of the miss match. Not good. If you order one, make sure the shaft diameter is correct for the coupler you intend to use it on. It probably works Ok on the correct coupler.
