etrailer Trailer Coupler Latch Lock - 1/2" Span - 1/4" Diameter - Stainless Steel - e98885

Average Customer Rating:  4.9 out of 5 stars   (54 Customer Reviews)

This rustproof, stainless steel lock is designed to fit latch-style trailer couplers. Covered keyhole helps to prevent internal corrosion. Can be keyed alike to match other etrailer locks.


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.



These are still working great and keyed alike has simplified my key rings. Highly recommend these


Nice product and great price


Put two of these on my boat and ATV trailers. Work perfect. Fast shipping, too.


We are very pleased with the lock and especially with its companion hitch "stinger" lock that is identically keyed. Etrailer was very accommodating in working out the keying for this product. highly recommended!

We continue to give these locks a 5 Star rating!


The lock is really excellent quality. I use it to secure a kayak trailer. So it's really only exposed to summer type weather. The service from etrailer was quick and efficient.


Product was as advertised, and company offered great customer service after a snafu with the Post Office. Will order again from them for our trailer needs.



Love the lock, easy to use and keeps the trailer secure....definitely recommend.


Love it. It fits in the safety pin hole on a 2” ball hitch. I also got mine keyed alike. That is a pretty good idea to offer as an option.


Good little item, but stout. Keyed end is screwed on/off with key inserted. Remove the key, pop the cap on and it's ready to go. Will be used to secure bikes to Swagman hitch carrier for travel and/or storage. Swagman carrier is secured to an anchored stand for storage


In doing business with etrailer, it was a great and easy process.
All of the people I talked were more than helpful.
Their bosses should be very proud of their performance.
I bought 4 coupler locks to use on my trailers and one key fits them all.
Thank you so very much!


This coupler lock a quality product. Perfect for the application which I'm using it for, which is for locking the spare tire on the bracket fabricated.


Excellent quality - great customer service - got mine keyed with hitch receiver lock both by Deadbolt - great products and look great and are very secure locks!! Really happy with both!!!


Both stainless hitch and coupler locks were exactly as decribed and were delivered promptly. I use for all my towing related equipment.


Delivered at my door on the promised day and excellent quality.


Just what I needed. These guys have everything. Very quick shipping and arrived as stated. Their videos are great and helped me decide on which locks I needed.


This product is perfect for my needs. The lock has a dust cover that keeps it clean no matter the conditions. Just a fantastic product and a very reasonable price that does what it claims!


quality product as always from etrailer. I really liked having locks keyed the same, tired of having to keep up with soo many keys.


Great Product.... Great Service.... Fast Shipping and easy installation......etrailer is the best..... Thanks Madison P


Love the option of keying them alike, no more fumbling around with three key for three locks anymore!


I bought these locks because they are all keyed alike. Works great.


Great product - had the smaller for my 1/2 ton truck but got the larger one. Great service from Etrailer - quick service


Very knowledgeable, found the right parts. Thank you!


As described, quality product, made in USA.


Good lock, keep lubed while out in the elements.


Just as described. Read the instructions before installing and there will be no issues.




Product works great!

  • Recommended Keyed Alike Lock for Latch Style Trailer Coupler
    We sure can, but the Master Lock # 605DAT lock you'd looked at isn't available keyed alike. We do have options for keyed alike coupler locks, however. I'd recommend a latch lock such as the etrailer brand # e98890 for a 7/8 inch span or # e98885 for a 1/2 inch span. The locks are constructed of stainless steel for superior corrosion resistance and are available keyed alike. Just choose 'keyed alike' on the drop down menu on the product page and choose your desired quantity. You'll want...

  • Can Coupler Locks and Hitch Receiver Lock be Keyed Alike
    All three locks you mentioned are from, and because of that you will be able to get them all keyed alike. You will need to select "Keyed Alike" in the drop down menu when ordering our Hitch Receiver Lock # e98881, our Stainless Steel Trailer Coupler Lock # e98885 and our Trailer Coupler Lock # e98894, and the three locks must be placed in the same order.

  • Coupler Latch Lock That Cannot be Easily Cut With Bolt Cutters
    Yes, the best way to deter thieves with bolt cutters is to use a very short pin lock in the latch part # e98885. This stainless steel coupler lock only measures a 1/2" span and will not give the thief room to use the bolt cutters to cut it off because it is too tight against the latch. As long as the hole in your latch is a 1/4" and the latch is no wider than 1/2" this will work well for you. They can also be keyed alike so you can use 1 key for your work trailers.

  • Can I Get Keyed Alike Locks For My Different Hitches and Trigger-Latch Coupler?
    Yes! So you would need the etrailer Hitch Receiver and Coupler Lock Set # e99039 which comes with a 2" hitch pin lock and a 1/2" coupler latch lock. Then you can also get the etrailer 1-1/4" hitch lock # e98879. If you select "Keyed Alike" and they are all in the same purchase order, then we will put keyed alike lock cores into all of them before sending them out. You can also get them separately: etrailer Trailer Coupler Latch Lock1/2" Span - 1/4" Diameter # e98885 etrailer Hitch Receiver...

  • Recommended Coupler, Coupler Latch and Locking Hitch Pins All Keyed Alike
    I may have a solution for you, but those MasterLock trailer locks you were looking at unfortunately cannot be keyed alike, so you'd need some different options. For the coupler locks I recommend using the etrailer 2-5/16" coupler lock # e98894 or etrailer 1-7/8" or 2" coupler lock # e98893. For the latch lock I recommend using the etrailer # e98885 and for the locking hitch pins I recommend using the # e98882. You could have all of these parts keyed alike so you'd only need 1 key.

  • Replacement for Deadbolt Brand Coupler Lock & Can They be Ordered With Specific Keys
    I can answer each of these questions for you, and the etrailer Stainless Steel Trailer Coupler Lock - 1/2" Span # e98885 is the same as the Deadbolt RC2-SS that you previously purchased. Just part of the lock is not available for replacement, unfortunately, so you will need a new lock in its entirety. Also, specific key/lock numbers are not available so the key code you get will be random. If you want everything keyed alike you would have to get all new locks and select the "keyed alike"...

  • Corrosion Resistant Coupler and Receiver Locks to Secure Trailer
    We don't have exactly what you're looking for, but I may have a solution for you. The etrailer Trailer Hitch Receiver & Coupler Lockset # e99039 has both a hitch receiver lock and a coupler lock that are keyed alike. However, they are not stainless steel. They're steel with double-chrome plating to resist rust and corrosion. If stainless steel is more important to you than having them keyed alike, the Blue Ox Trailer Hitch Receiver Lock # BX8858 will lock your ball mount to your receiver...

  • Can Deadbolt Hitch Lock # 40107 be Keyed Alike to Coupler Lock
    Yes, if you select "keyed alike" on the product page for the hitch lock part # e98882 and on the page for the coupler lock part # e98895 you'll get both the coupler and hitch locks keyed alike. If you had a different coupler lock in mind you'd be able to do the same thing to have it keyed the same as the # e98882.

  • 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.

  • Coupler Pin Lock Recommendation to Protect Against Bolt Cutters
    The best defense against bolt cutters for coupler pin locks is to go with a coupler lock that fits the coupler latch so tight that a bolt cutter couldn't fit. The part # e98885 has span of just 1/2 an inch so it would be hard to get bolt cutters on the pin to cut it.

  • 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. They offer the etrailer Stainless Steel 2 Inch Hitch Receiver Lock, part # e98882, which will fit most 2 inch hitch receivers, and has an inside width of 2-5/8 inches. 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...

  • 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.
