Expert Answers about Trailer Coupler Locks


  • Best Wraparound Trailer Coupler Lock with 5" Wide Lip
  • The trailer coupler lock I recommend for a trailer coupler with large lip is the Master Lock Universal Trailer Coupler Lock part # 379DAT because the lock does not span the width of the coupler therefore the large lip is not nearly as much of an issue. The Blue Ox Trailer Coupler Lock part # BX88351 and options like it max out at around 4-3/4" wide.

  • Coupler Lock for Trailer Coupler with Rolled Lip
  • You are absolutely right that the rolled lip on your trailer's coupler will prevent using some types of locks but we do have a solution for you. If your coupler measures no more than 4-1/2-inches wide (including the lip) you can use the Fastway Universal Trailer Coupler Lock # DT25013KA. If it is wider then instead you can use Master Lock # 377DAT. The coupler lip appears too tall to work with lock # ML389DAT.

  • Recommended Coupler Lock That Can Be Keyed Alike
  • I do have a great option for you, however the Blu Ox Trailer Coupler Lock # BX88351 that you referenced cannot be keyed alike with other units. If you were to order 7 of these locks you may get 7 different lock cores/keys. For a similar coupler lock that can be ordered keyed alike I highly recommend the Fastway Universal Trailer Coupler Lock # DT25013KA, which like the Bulldog model will fit 1-7/8", 2", and 2-5/16" hitch balls. It features an anti-drill pin that discourages drilling...

  • Coupler Lock for Dexter DX12.5 (Model 10) Actuator with Wide Lip
  • The Master Lock Trailer Coupler Lock # 377DAT you purchased can accommodate a max coupler width (including lip) of 4 inches , so for a lock that works with up to a 4-3/4 inch coupler width, I recommend the Blaylock EZ Lock Trailer Coupler Lock # BLTL-33-40D. I pulled our Titan Model 10 actuator # T2477600 (Dexter DX12.5), and found that it measures just over 4-5/8 (4.63) inches edge to edge of the coupler lip, so the BLTL-33-40D will definitely be wide enough and work perfectly with...

  • Recommended Lock for Demco eZ-Latch Coupler
  • To secure your PJ Trailer that's equipped with the Demco eZ-Latch Coupler # DM14040-81 I highly recommend the Fastway Universal Trailer Coupler Lock # DT25013KA, which doesn't require a lip on the coupler for a proper connection. This is a heavy-duty lock that uses a ball and shackle to prevent potential thieves from coupling their truck to the trailer and taking off. Its hardened chrome-plated construction will resist corrosion and the bolt-blocked locking system prevents the lock from...

  • Will BOLT Trailer Coupler Lock Fit 4-3/4 Inch Trailer Coupler Width
  • The BOLT Trailer Coupler Lock has a 5-1/2 inch inside width, so it will fit the 4-3/4 inch width of the coupler on your 2020 Jayco Travel Trailer with no problem. There are a couple of different BOLT coupler locks for Fords, and I have added a photo showing the difference between the keys for the BOLT Trailer Coupler Lock - 1-7/8", 2", and 2-5/16" Couplers - For Ford Key # BL7032491 and For Ford Side Cut Key # BL7032496. It looks like you have a 2018 Ford F-350, which means the latter...

  • How to Use the etrailer Coupler Lock for Flat Lip Couplers
  • I can absolutely explain how the etrailer Trailer Coupler Lock for your flat lip coupler works, and it is extremely simple. What happens is you will slide the lock over your flat lip coupler, and push the pin up - it won't take any strength at all, you can do it with a finger. With the pin up, just turn the key and you're done; it's locked to the coupler. When you want to remove it, turn the key in the opposite direction and the pin will come down. That's literally all there is to it!...

  • Is the Blaylock EZ Lock Coupler Lock Part BLTL-38 Easy To Cut Through
  • The Blaylock EZ Lock Coupler Lock part # BLTL-38 is indeed made of aluminum which is a softer metal. However, if a would be thief has any sort of powered saw on hand they are going to get though most locks no problem and that's just the said reality of it unfortunately. If you prefer a coupler lock made of steel then you can use the Master Lock Trailer Coupler Lock part # 377DAT or the Fastway Universal Trailer Coupler Lock part # DT25013KA which would indeed be more difficult to cut though....

  • Alternative to Blaylock Total-Encasement Coupler Lock that Fits Standard Lipped Couplers
  • Thank you for sending the photo! While I have a solution for you, the Blaylock Total-Encasement Coupler Lock, part # BLTL-23 will not work. I is designed to fit Bulldog Collar-Lok style couplers that use a 2-5/16" ball, like # BD028463 for example. For a lipped coupler, like yours, Blaylock does offer the EZ Lock Trailer Coupler Lock for 2-5/16" Lipped Couplers - Aluminum - Push Button # BLTL-34. Or, if you prefer something that provides a more complete enclosure for your coupler,...

  • 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...

  • Can Puck Lock Be Used with Blaylock EZ Lock Trailer Coupler Lock # BLTL-33
  • The Blaylock EZ Lock Trailer Coupler Lock # BLTL-33 is designed to work perfectly with a standard padlock, but I think the typical opening size on the back of a puck lock will be a bit too small to fit over the end of its pin/shank. The pin/shank on this lock has a 3/4" diameter, while for example the opening on the Master Lock Puck Lock # ML6271 we have available has a height of just 19/32", which wouldn't allow it to mount over the pin. Your best option is going to be with something...

  • Can the Master Lock Trailer Coupler Lock be Keyed Alike
  • I have a solution but unfortunately the Master Lock Trailer Coupler Lock part # ML389DAT can not be ordered with a specific key number. Instead the etrailer Trailer Coupler Lock for Flat Lip part # e98895 can be ordered keyed alike. It doesn't work on the 1 7/8" coupler, for that use the etrailer Trailer Coupler Lock part # e98897. These are very nice quality locks that will keep your trailer secured. Check out the video I did on them that I have linked it for you.

  • Coupler Lock for 2-5/16" Trailer Coupler Ball
  • We do not have any type of database of parts lists on each year, make and model of trailer so while we cannot tell you what type of coupler you have on your 2005 Airstream there are universal applications that should work. I recommend checking out the Master Lock Trailer Coupler Lock # ML389DAT which will work on your Airstream if you have a standard lip, rolled lip, straight lip, surge brake, hammer blow or UFP couplers. If you take a look at the accompanying photo you can see how...

  • Recommended Coupler Lock for 2020 Airstream Flying Cloud with Demco eZ Latch Coupler
  • The best locking device we have for a 2020 Airstream Flying Cloud with Demco eZ Latch Coupler is the etrailer Trailer Coupler Lock part # e98887. There should be a pin hole on the side of the coupler which this lock will fit into and stop either a hitch ball from being coupled or uncoupled. If you are looking for a wrap-around style lock, you could use the Fastway Universal Trailer Coupler Lock part # DT25013KA. That said, you could use both lock styles as well if needed.

Instead, I recommend the Blaylock EZ Lock Trailer Coupler Lock part # BLTL-33-40D. In order to break though this lock you would have to cut though a 3/4" thick hardened steel pin which is easier said than done. This would require power tools but if a would-be thief does have...

You will simply need the longer hitch pin. The Trailer Hitch Receiver Lock - Extra Long - Flush Design for 2-1/2" Trailer Hitches # RH5-XL will work well for you and give you adequate space.

  • Locking Hitch Pin, Coupler Lock and Coupler Latch Lock for 3 Inch Receiver
  • The span of the hitch locks included with the Reese Tow and Store lock kit don't have a span long enough to work with a 3 inch receiver. However, you could piece together a kit that'd work for you. For the receiver lock, I'd recommend the Draw-Tite # BD580412 which offers a 4 inch span and uses a high security key. For the coupler lock, use # DT25013KA and for the coupler latch lock, use # 605DAT. ..

  • 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 etrailer.com 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.

  • Recommended Trailer Coupler Lock for Coupler with 5" Wide Lip

I looked though our options and none of the wraparound styles will work with a 5" wide lip on the coupler.

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.

This has the TL 33 and then what I could find on the TL 45 is that it's the same part as the circular padlock on this coupler lock. This has an aluminum construction so it will hold up really well to the elements and it fits a wide variety of couplers on the market. Attached is a sample installation video for you to check out.

  • Realistically, the Master Lock Trailer Coupler Lock # ML389DAT won't be pried off; even if there's enough room to fit a crowbar, getting it fully wedged in so that enough leverage can be applied to the lock to break it off just isn't going to happen. Theoretically, any lock can be busted with enough force but the odds of your trailer getting stolen with this lock on it are extraordinarily slim compared to not having the Master Lock on.

  • Coupler Lock Comparison for Securing a Travel Trailer

  • Replacing Lost Key To Bulldog Hitch Lock

If you can't find a replacement key, I recommend replacing this with a Master Lock Trigger Style Coupler Lock # 605DAT...
