I asked to have 3 locks keyed the same. This was done in record time I received the product in 3 days. Great service! 173559

This has been a great lock for my hitch. No rust, and a solid little lock. The 1/2" version fit perfect on my Bulldog hitch. The 7/8" lock was a bit too long, so be sure to measure. I also got the larger receiver lock, also in stainless, and also a fantastic lock. You can get both locks keyed the same so there's one less key to worry about. Highly recommended! 313754

Still working great! No signs of wear. Very happy with these locks.

Like the design, but had lost the keys and had to break them. Literally one hit with a hammer and the broke off. They keep honest people honest, but are a low grade level of protection. 477828

Product construction is very good. At the time of purchase, I did not realize the different type of locking mechanism. The unit locks using a 1/4-20 stud threading into the shaft portion of the lock. A bit weird at first use, but got used to it. I did contact eTrailer and asked some questions. The rep was very nice and down to earth. 306009

I ordered several at the same time so that I could get them keyed the same. They were. They fit my trailers as planned. Now I will see if they can withstand the "test of time". Being stainless I hope they do. 277701

I purchased this for my Keystone Laredo Travel Trailer. I could not use this in my application because the side barrels were too big to close the latch. (the locking hole was too close to the hitch structure) I feel that this is a quality lock and liked the Stainless construction. I believe that it would have worked great and saved it for future trailers. I purchased a locking assembly from another company for my travel trailer. Small Company, best lock out there for this application. E-Trailer should sell these. 376047

Nice quality coupler lock. Nicer than other name brand locks. Hopefully it will resist corrosion as advertised. 849304

by:

This was a lot lighter than I expected but a lot more sturdy build than the yellow, red and black plastic ones i've used (I'm leaving out brand names but these colors should help). Like all of them I'm concerned about how brittle the material gets in the cold of winter in Alaska but like anything, if somebody wants it they will get it. 800185

The Deadbolt Stainless Option is the way to go. The fit and finish was excellent. eTrailer has been great the whole way. Thanks etrailer for the products and service. 446067

by:

This is a good unit, I have one like it for the receiver. However, this one doesn't fit my trailer. The large diameter ends are too big to fit. My coupler doesn't have enough height between the center of the hole and the top of the coupler head. It would be helpful to include this measurement on the description and/or video. I feel that my coupler is a common size/style but cannot use this device. 436952

Product is good--However a couple of problems--in very cold / snowy weather, as experienced in northern Ontario, Canada, lock can freeze up. Needed to heat the key and lock with a lighter, then try to insert the heated key to thaw the workings. Then sprayed in lock thaw product. Yes, the rubber / plastic protective end cap was in place prior to trying to unlock. 282780

Lock seal still intact and lock performing flawlessly and I install /uninstall lock at least weekly. 271943

I bought this to compliment a trailer and receiver lock that I had purchased earlier and had it keyed to match. Worked great and etrailers customer service was excellent, as always. 190616

  • Comparison of the Deadbolt Coupler Lock and Master Lock Adjustable Coupler Lock
    The main difference between our etrailer.com Coupler Lock, item # e98890, and the Master Lock Adjustable Trailer Coupler Lock - Stainless Steel, item # 2847DAT, is the style of the locks. The Masterlock has the advantage of being able to be used on many different styles of coupler and has a normal style key that can be duplicated at a local hardware store. The Deadbolt has a short span, 7/8 inches, so it can be flush to prevent removal. This style is more compact than the stick and...

  • Coupler Pin Lock and Ball Mount Lock Recommendation Keyed Alike
    Sounds like you'd want our etrailer.com Pin Lock part # e98890 for the pin lock and then for the 2 inch hitch lock you'd want the hitch lock part # e98880 which you can then select keyed alike on both from the drop down menu and they'll come with the same lock core.

  • Comparing the Stainless Steel Trailer Coupler Lock e98890 and Trailer Coupler Lock e98889
    The Stainless Steel Trailer Coupler Lock part # e98890 is made of stainless steel, not chrome plated which is why it is more expensive than the Trailer Coupler Lock part # e98889 which is chrome plated steel. The stainless steel option is better as you don't run the risk of the chrome plating chipping and exposing unprotected steel. In regards to the Bulldog Lifelong Trailer Coupler Lock part # BD580403, this will work with pretty much any trigger style latch with a 1/4" diameter pin...

    We have coupler pin lock locks that can be keyed alike like the part # e98888 which has a span of 3-3/8 inches and # e98887 which has a 2-1/2 inch span. Or even # e98890 with a 7/8 inch span or # e98886 which has a 2 inch span. On the product page you'll select keyed alike on the drop down menu and all of the locks will use same key.

  • Do you Have the etrailer Trailer Coupler Latch Lock with a 1 Span
    The closest I have to the 1" is the etrailer Trailer Coupler Latch Lock part # e98890 which has the 7/8" span. There is some excess threading in the lock when installing it that will allow it to work with your 1" span requirements. Unfortunately they can only be keyed alike when ordered together.

  • How To Order Stainless Steel Hitch Locks and Coupler Locks to be Keyed Alike
    For stainless steel coupler lock and hitch receiver lock that can be keyed alike, I would recommend the etrailer brand locks.

For coupler locks they offer the etrailer Stainless Steel 7/8 Inch Span Coupler Lock, part # e98890, which has an inside width of 7/8-inch, and the etrailer Stainless Steel 1/2 Inch Span Coupler...

  • Do Locking Hitch Pins have a Towing Capacity and Multiple Hitch and Coupler Locks Keyed Alike
    Trailer hitch lock # e98882 does not have an official weight capacity because it exceeds what the trailer hitches are capable of (for Class III and IV hitches). So it can handle a 10,000 pound trailer or more. The diameter of the thicker ends of this lock are approximately 1 inch. Lock # e98890 is a coupler latch lock. The diameter of the pin is 1/4 inch. The length of the pin is 7/8 inches. The ends are 1 inch in diameter as well. Since this is for the trailer coupler it would not interfere...

  • 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 # DT25013KA which can also be keyed alike and add even more security. I've attached a video review to assist.

  • Recommended Coupler Locks for Bulldog Cast Head Coupler # BDA256C0317
    I pulled one of the Bulldog # BDA256C0317 couplers off the shelf, and tested it with various coupler locks. Other than our etrailer.com locks like the # e98890 that pass through the latch, I found three locks that would work pretty well for you. The fit of the Blaylock EZ Lock # BLTL-33 was a bit loose, but once the locking bar was slid into place, I was unable to remove the lock by hand, although a pry bar might get it off.

    The Master Lock Trailer Hitch Receiver Lock and Coupler Lock Set - 1-1/4" and 2" Hitches # 3794DAT are keyed alike, but adding the extended length locking pins will not allow the keyed alike to also include those pins. For the 3-5/8 inch usable length, I recommend the etrailer.com Trailer Hitch Receiver Lock - Extra Long # e98881 which can be keyed alike.

  • Can Master Lock Trailer Coupler Locks be Keyed Alike?
    The Master Lock Adjustable Trailer Coupler Lock - Stainless Steel # 2847DAT is not offered in a keyed alike option, so if you order 3 you will have 3 separate keys.
