Ordered 4 keyed alike. Received 4 locks with 2 keys that only open one lock...poor quality control.

Customer Service will fix this for you.
-- Etrailer Expert Sierra K - 06/13/2022


Pretty nice having all trailer tongue locks and hitch pin locks keyed to 1 key for all my trailers and trucks


easy to remove and put back on. works g reat!


Good lock, good quality, would recommend. Tried to get keyed alike with other locks in same order without success.


Great product fantastic price super fast delivery.


For over a year I've used this keyed alike trailer latch lock with three larger hitch locks in extended desert and winter weather both on and off road. It is great that all are keyed alike so I only have one key for four locks! This lock, as the other hitch locks, still locks/unlocks smoothly. I do wish eTrailer would offer heavy duty exterior weatherproof padlocks that could be keyed alike with these hitch locks. That way one key would work for all the hitches, storage shed, propane tank compartment, battery compartment, boat motor chain, boat storage compartment, bicycle lock, gate lock, tool box lock...that's a bunch of locks I'd buy again if I could get quality locks all keyed alike. Money burning a hole in my pocket.


Strong and easy to put in and take off.


Just what I need to keep my trailer and spare tire in place, thanks.


Excellent customer service and quality products


Have used it twice now on two different trailers and it has been great. The construction seems heavy duty and will definitely last however it's heavier than expected. The adjustability factor is great since my new 3/4 ton truck sits higher than my previous 1/2 ton and my trailers are different heights as well. I switched out two of the three pins for locking pins that I also purchased through etrailer to ensure no one walks off with it. Overall I'm very satisfied with the purchase.


A nice addition of security and with etrailer key alike feature easy to use.


Great product! I selected "keyed Alike" on many locks (~12) of this brand and they all came keyed the same. Makes it easy that we don't have to carry many keys for all our different trailers and trucks. One lock came that did not work with the others and a quick email to Etrailer and they shipped me out a replacement lock quickly for the defective one. I would order them again, Thanks


Ordered two of these and had the locks keyed the same. They arrived promptly and all the keys work as they are supposed to. Fits great on my ATV and boat trailer hitch latch.


WhEn I called in I was reminded that I could have this keyed alike with a hitch pin lock I had bought previously. Awesome customer service by Dana!!!


This is a great product to have when you have two trailers and your Hitch receiver keyed alike. Etrailer made it happen with one easy call, thanks again!


Item arrived in a timely manner and was well packaged. The trailer coupler lock works exactly as described and is highly recommended.


Great product, awesome price. Great recommendation from the staff at Etrailer!! Awesome folks to work with, very knowledgeable and friendly. Highly recommend this product and these people!


Good lock but not exactly as pictured. The one I received does not have the rubber cover on the keyed side.


I bought a hitch lock and two coupling locks. They all arrived on time and keyed the same. Great service!


Fast delivery and high quality. You do have to turn it several times to unlock and lock, but the key goes in easy and is easy to turn. I would definitely recommend this lock.


I've had this lock on my truck for a year now and it is still as good as new. I have only removed it once to swap a ball about a month ago and still the lock cylinder worked as smooth as it did when I first installed it.


Although I do not use these locks for a trailer hitch, they work perfectly for my application


Great service,E Trailer the only ones I have to go to when we need something here at the ranch for the trailers. Thanks


Was just what I needed. All of these products are high quality. Would go here first to buy anything else pertaining to my truck.


Product is just as described. Seems to be a quality built product. Fits well with the angled surfaces were the flat ones have not fit in the past.

  • Replacement Keys for Locks
    Yes, the keys from our Coupler Lock, # e98889, and other locks can be replaced if they are lost, but I strongly recommend recording the key number that is stamped on the key. The key number is used for replacement keys, so I recommend writing the key number down and keeping it somewhere safe just in case you lose the keys. This key number should also be stamped on the lock core. The key number will be 3 digits and it usually starts with a zero. If you do not...

  • Recommended Keyed Alike Coupler Latch Lock
    I have a solution for you, but the Buyers Products Coupler Latch Lock is not available as a "keyed alike" lock. I recommend using the etrailer Trailer Coupler Latch Lock - 7/8" Span - 1/4" Diameter - Chrome - Keyed Alike # e98889, which can be ordered keyed alike. These are made from durable steel and have a nice chrome finish, and the locks have dust covers to keep the moisture and elements out, so they're going to last a long time. I've linked a short review video of these for you to...

  • Can Trailer Coupler Locks be Keyed Alike
    Yes you can get the Trailer Coupler Lock part # e98889 and part # e98881 keyed alike if you wanted. You would just need to select the keyed alike option from the drop down menu by the add to cart button.

  • Non-adjustable Boat Trailer Coupler Lock
    I was able to find a boat trailer coupler lock that isn't adjustable but it is a bit larger than what you specified. I recommend the etrailer Trailer Coupler Latch Lock Chrome item # e98886. This coupler lock has a 2" span, is 1/4" diameter, and nonadjustable. I have attached a couple of review videos.

  • Do the Trailer Coupler Locks Have To All Be Purchased At the Same Time for Keyed Alike
    Correct, the Trailer Coupler Locks like part # e98895 or part # e98889 must all be purchased at the same time in order to take advantage of the keyed alike option. I wish we could match the lock to a set of keys you already have but this is simply not possible from our side of things. Therefore, it would be best to order a few extras if you think you will have multiple trailers. The coupler and pin locks will also both come with the same lock code if ordered together and the...

  • Recommended Trigger Lock Replacement Keys or Keyed Alike Options
    The Trailer Coupler Lock - Butterfly Style # 3008 do not have specific key blanks available or a keyed alike option. You would need to simply have a similar key blank cut for replacement or spare keys. If you are wanting the trigger latch lock to be keyed alike, we don't have the butterfly style option, but I instead recommend the 7/8 inch span # e98889 or the 1/2 inch span # e98885.

  • Recommended Trailer Coupler Lock for a 2018 Keystone Passport 2520RL
    The majority of the butterfly coupler locks like part # 3008 have a 3/4" wide span. If the butterfly coupler lock that you previously used was too tight then chances are this one will be too tight as well. I recommend using a straight pin style lock like part # e98889 which has a 7/8" span with a 1/4" diameter pin. This coupler lock can also be keyed alike to a trailer hitch lock like part # e98880 if both were ordered at the same time. I have attached a review video of the coupler lock...

  • Latch Width and Hole Diameter for Trailer Coupler # CA5400
    I went out to the warehouse and pulled trailer coupler # CA5400 to measure the latch width and its hole diameter. The latch outside width is just over 7/8 of an inch at 0.88 inches. And the hole diameter is just over 5/16 of an inch at 0.32 inches. If you end up needing a lock our lock # e98889 is a good choice. It has a 7/8 inch span and a 1/4 inch diameter pin.

  • Is the Masterlock Trigger Style Coupler Lock Available Keyed Alike
    The Master Lock Trigger Style Coupler Lock # 605DAT is only available as keyed unique. For a keyed alike option you can look at the etrailer Trailer Coupler Latch Lock # e98889.

  • Alternative for Pin Lock for TorkLift GlowStep Scissor Steps
    The etrailer Trailer Coupler Latch Lock part # e98889 is very similar to the Pin Lock for TorkLift GlowStep Scissor Steps part # TLA7509 so you should be able to swap the two without issue. The etrailer lock is threaded unlike the TorkLift so there will be no accidental unlocking.

  • Recommended Hitch Lock And Coupler Lock That Can Be Keyed Alike
    We have exactly what you are looking for. I recommend the etrailer Hitch Receiver and Coupler Lock Set # e99039 which includes a 5/8" diameter lock for a 2" trailer hitch receiver, and a 1/4" diameter lock for the trailer coupler. You can get two of these sets keyed alike by selecting keyed alike from the drop down menu on the product page, and changing the quantity to 2. I included a video of the etrailer # e99039 for you to take a look at.

  • Recommended Trailer Hitch Pin Lock for 1-1/4 Inch Hitch With Matching Trailer Coupler Pin Lock
    In order to obtain a trailer hitch pin lock for 1-1/4" hitches as well as a trailer coupler pin lock that uses the same key you will have to use the Trailer Hitch Receiver Lock part # e98879 and Trailer Coupler Lock part # e98889.

  • 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...

  • Recommended Trailer Coupler Locks That Can Be Keyed Alike
    I have another option for you, but there is not a way to get 5 of the Bulldog Lifelong Trailer Coupler Lock # BD580403 keyed alike. Instead I recommend the etrailer Trailer Coupler Latch Lock in Stainless Steel # e98890 or Chrome # e98889 which can be keyed alike. All you will need to do is select the keyed alike option from the drop down menu, and change the quantity to 5 before adding them to your cart. I included a video of the etrailer # e98890 and # e98889 for you to take a look at.

  • Recommended Solution to Lock Trailer with Weight Distribution System Attached
    It sounds like you're looking for a solution to lock your trailer coupler while the weight distribution hitch is still connected to the trailer, and I think you might be referring to a Fastway E2 weight distribution hitch. We do not have an e-trailer branded weight distribution system available. With all of that said, we do have some solutions that can help provide an added layer of security to your trailer, but you won't want to use the Tow Ready # TS84FR since you won't have the ability...

  • Couple Lock Recommendation that Can be Keyed Alike
    I have a solution for you, but the Bulldog Coupler Lock part # BD580410 that you referenced can not be keyed alike. For a similar lock that can be keyed alike you would want our lock part # e98886. The usable span of this lock is 2 inches. For one with a 7/8 inch span you would want the # e98889. Or for 2-1/2 inches, part # e98887.

  • Channel Mount Trailer Coupler for 3 Inch Wide Channel
    There is pretty much a standard for channel mount couplers such as # DM12113-95. The channel width is usually 3 inches and the couplers are usually around 2-7/8 inches wide to fit in the 3 inch wide channel. Once torqued down there is no side to side movement because the coupler essentially is clamped in. Holes are usually spaced 2 inches apart on center which is the vertical hole spacing in a channel this coupler would work with. But it never hurts to measure just to be sure. For mounting...

  • Locks for A-Frame Trailer Coupler
    We have all sort of trailer locks including coupler locks for a-frame trailer couplers. Please refer to the linked page that displays all standard coupler locks. You can use a universal-fit surround-type lock such as # ML389DAT which fits all ball sizes and that prevents someone from hitching to your trailer by clocking access to the coupler, or a simple latch type lock like # e98889 that prevents the coupler latch (like the one on # CA-5400-B) from being lifted to unlock the coupler.

You would just need to select the "Keyed Alike" option on the product page.
