Works like a lock should. 391100
I Love the hitch. The lock didnt work with the pin diameter of the B&W Companion Gooseneck-to-5th-Wheel Trailer Hitch Adapter Item BWRVK3500, so went a different route.
Christopher W - 06/11/2018This trailer tongue lock is easy to use and it is just grand that the same key works on the tongue lock and ball latch!! I have been buying all of my trailering accessories from these folks for years and I will continue to do so since they have a great products, are knowledgeable, and provide great customer service! D.

Works Great 623207
I received the product as described and at the time stated. Will definitely use them again for future needs. 594687
Fit my enclosed car trailer rear door perfect and matching keys a plus for sure :) 594413
The lock has to hang sideways. Because of this it fills with water and freezes in winter. I had to cut reliefs to drain water. Poor. 566646
I will be towing an enclosed trailer loaded with some rather valuable items on board. These locks fit the trailer hasp's perfectly I am totally confident in their ability to keep my goods on board and safe! Thank You etrailer again! 548133
Great customer service! My order arrived quicker than promised & that’s always a nice surprise. I would recommend etrailer for all RV needs. Thank you. 483396
As per selection offered by etrailer.com of three discus Master padlocks with 3/8" shanks keyed alike, we are very pleased with the quality of the product received, as well as the fact that no hardware stores in the Reno/Sparks NV area carried a three pack of these types of locks keyed alike. This makes for very simple ease of use in our situation as well as having the security of discus locks in our application. Also, no hassles or issues in ordering these locks on line. Delivery info on web site was straight forward, accurate and timely. Will considering using etrailer.com again in the future. 477363
Fine. Thanks for your concern! Good product!
Sue - 02/20/2019Good good 468762
Very professional 445771
These locks have worked exactly as anticipated. One of them out of 5 is corroding and is a little hard to open & close, but still works. Still a good product and is nice to only need one key. 444777
Has it really been a year? I bought those products for my wife, she is very happy with all. And if she is happy I'm happy. All work and fit like they are suppose to. 439327
Very good quality at its price! 418407
Quick delivery on a great product...... Thank you 405409
Clumsy and sticky to lock and unlock. I ended up putting a dry lubricant in the lock to get it to function smoothly. I am conerned that under adverse weather conditions the lock may not work smoothly. etrailer was terrific, arrived quickly, no issues, all locks properly keyed. I still use etrailer and it has been an excellent resource for trailer issues. 404894
etrailer was able to help me buy 5 keyed alike locks. My experience is that etrailer's customer service is great and they're competitively priced across their entire product offering! 399116
It was easy to order, the locks came quickly. The locks were just as I had ordered them. It will be great to have locks keyed alike so I only have one key to carry. Thank you ! 383483
Fast and Great Service. Great product. 350553
Secures the coupler locks and the spare tires on all of our trailers...make sure to remember to check the keyed the same box...so no matter what truck or tractor key ring you happen to have on you, you'll have that same trailer lock key...:) 343473
Got exactly what I paid for. Nice masterlock disk locks all keyed alike. Thanks a bunch! 324922
Great. I purchased 13 of these using in a laundromat and havent had issues with any of them. Still very happy with the purchase.
JustinV - 12/14/2017This is my second lock of this style. It is a high quality very secure lock. I plan to order several more like this to replace some less secure locks. 292223
Great 291316
great locks 271753
it is a good lock will be hard to cut o ff 260548
The product came just as advertised it is definitely well-built and I'm sure it will work. like other reviews I've seen, it would definitely take a lot of noise and a big hammer to knock it off the tongue.i'm happy with the product. 252012
Product was just as advertised. I received them quickly and am very happy with locks 235850
I bought this as part of a complete tow package that I needed to install. Not only did I get everything I needed and verified by customer service, but they also made sure it was rush shipped to me during Christmas weekend. Awesome products and service! 234427
tire and lock was what I needed to finish up my paint trailer to put it in service. E-Trailer is a outstanding company to deal with price was great and customer service was outstanding A+++++ on getting shipping problem handled. Thanks again E-Trailer for a great product will use you again for sure 224745
ok 211688
We ordered 2 of these locks to replace locks already used in our fleet. Specificially we needed them keyed to match our other locks as identical keys are already used by over 50 people within our company. The customer service team was great, assuring they would cross check their inventory for locks coded to the right key or specifically order them in for us. They had them in stock and sent them to us right away, and everyone's pre-existing keys work in them perfectly. THANKS FOR YOUR HELP! 206819
Good product and great service. Thanks 176630
These locks are exactly as described and I was glad to get 3 which are all keyed alike. Very fast shipping and great customer service. 172914
What a great combination! The Baylock EZ lock is much better than what was available at local shops. With the Masterlock, which fits perfectly, I feel that my trailer is as secure as can be; thieves are inventive! Would highly recommend this setup. 172437
These locks are a good price and having them all keyed alike is a great feature! 168803
just as described, shipping was freaky fast! 157705
Products as described. Ordered on Monday and they arrived on Wednesday! Ordered two sets of wheel locks and they were "keyed" the same without even having to ask! Excellent responsiveness and follow-up. 148554
seems well built , time will tell 144642
Heavy Duty lock, works well with EZ Lock Trailer Coupler. 141199
Delivered on time. Locks appear to be good quality. Locks not made in the USA? 138654
Ordered 3 locks keyed alike. Very prompt shipping and the price was right. Smooth working mechanism and fit the trailer perfect. Kind of disappointed that they were made in china, but what isn't these days. Very satisfied with product and etrailer.com. 127402
Arrived on time. Coupler lock made well and lock is good also. A friendn of mine has a trailer coupler lock, easy to use and locks the trailer up good. 123492
This is a great heavy duty lock 118350
This is a great design - very difficult to attack w/bolt cutters - and etrailer.com was able to ship me 5 of them keyed alike to cover my entire trailer. One thing I would like to see - a simple sleeve, made of the soft silicone such as cell phone skins, in the shape of this lock. That would help keep the elements out and prevent metal-to-metal contact against the trailer. 115577
The Locks worked very well on the doors but are to large for the tongue.I wish they nade one to fit it. 112743
Fits very well, and makes me feel much better about leaving my trailer parked. We have had many trailers stolen from farms in this area, so it was imperative to get a sturdy locking system. Thanks for your product and fast service. 112484
I recently purchased this lock for my etrailer trailer hitch lock and they both are so very easy to secure and it gives me peace of mind knowing that these items are very safe and VERY easy to use!! I would strongly recommend these items for anyone who wants to know that his/her horse trailer is not going to be stolen! Thanks etrailer, Kathleen D. 103412
Smooth locked and unlock, a good product and work for my trailer. 92320
