  • 3/4 Inch Span
  • Steel

Combo pack offers theft protection for your trailer with the butterfly-style coupler lock and secures a ball mount or hitch accessory with the receiver lock. Chrome-plated steel resists rust. Ball-bearing locking mechanisms provide extra security.


Features:

  • Convenient set includes locks for your trailer's trigger-latch-style coupler and your 2" trailer hitch receiver
  • Coupler lock secures the trigger latch on your trailer's coupler to deter theft
    • Trailer can't be removed from your tow vehicle when locked onto ball
    • Would-be thieves can't secure your unhitched trailer to their tow vehicle
  • Flush-style hitch lock is used in place of standard pin and clip to prevent theft of ball mount or hitch-mounted accessory
    • Secure your bike rack, cargo carrier, hitch cover and more to your trailer hitch
  • Ball-bearing locking system on both locks provides maximum security and ease of use
    • Just pop the deadbolt onto the end of the pin and the lock will automatically engage
    • Grease ball-bearings periodically to ensure smooth operation
  • Solid steel pins offer superior strength and durability
  • Chrome plating resists rust

  • 2 High-security, square keys included


Specs:

  • Coupler lock:
    • Application: trigger-latch-style ball couplers
    • Inside pin length (span): approximately 3/4"
    • Pin diameter: 1/4"
  • Hitch receiver lock:
    • Application: 2" x 2" trailer hitch receivers
    • Inside pin length (span): 2-1/2"
    • Pin diameter: 5/8"
  • Limited 1-year warranty


The unique ball-bearing locking system on these Lifelong locks is supremely easy to use. When you pop the deadbolt onto the end of the pin, the integrated ball bearings engage the lock automatically.


This ball-bearing system also ensures that the structural integrity of the hitch lock's pin is maintained throughout. A typical padlock-style hitch lock has a significant taper at the end of the pin where the lock snaps into place. This taper weakens the pin, making it easier to break or cut. Because the ball bearings are responsible for engaging the lock on this Lifelong lock, no taper is needed. So, the pin diameter is the same along the entire length of the lock. The result is a hitch lock that is strong, durable and highly tamper resistant.

Video Transcript for Bulldog Trailer Coupler Locks - Latch Lock - BD580404 Review

Today we're going to review part number BD580404. This is the Bulldog Lifelong Trigger Style Coupler Lock. This convenient set will include locks for your trigger latch style coupler and for your 2-inch trailer hitch receiver. Now they do come with the plastic caps, which will cover the key slots, to help prevent the corrosions in the locks. They are chrome-plated to help resist rusts and they do come with the two high-security square keys. Now on this copper lock, what you will do is you put the key in; you just turn it to open it up and then what you would do, is this coupler lock, it will fit on the trigger latch style ball couplers.

The pin diameter right here is 1/4 inch. Basically, what you would do is slide that onto the latch on your coupler. Line this up, push it together, and then just push in your lock and its locked in place. You put your plastic cup over to protect it. Basically, the diameter, the inside pin length right here, will be 3/4 of an inch.

Now on the hitch lock, the flush-style hitch lock. This will be used in place of the standard pin and clip, that will prevent theft of your ball mount or any hitch mount or accessory. This is basically the same way you would take off the plastic cover. Have access to the key hole, put in your key, turn it; it would just slide off. Now it does use a ball bearing locking system on both of these locks, which will provide maximum security and ease.

Now basically you would slide this, remove your pin and clip on your hitch. Slide this through, put the end on, and then just push that and it's locked in place. Put your plastic cover back on to protect the keyhole. Basically, this will fit a 2-inch trailer hitch receivers. It has a pin diameter of 5/8 of an inch.

The inside pin length will be 2-1/2 inches. This part does come with a limited one year warranty and just to talk about the ball bearing locking system that we've mentioned right here; let me show it to you again. If you'd just open it up. You can see the ball bearing right here. The nice thing about that is that it ensures that the structural integrity of the hitch lock's pin is maintained throughout. Your typical padlock style hitch lock, will have a significant taper at the end of the pin where it snaps into place. This taper on the padlock style hitch lock will weaken the pin; makes it easier to break or cut. Because of this ball bearing design and they call this the Lifelong lock, there is no taper needed. So the pin diameter is the same along the entire length of the lock. The result is this hitch lock is stronger, durable, and highly tamper resistant. That should do it for part number BD580404.

The locks are still hard are work, I use them regularly. I do like them a lot except I sometimes struggle with the keys as they go in both directions, and turn both directions but only open one way. I also lost one of black rubber boot/cap, other than that they seem to work pretty good. 667804

The bulldog couple lock for my hitch jammed after using a few times and after three strikes with a hammer it broke so I could remove it. 608059

Nice, quality lock set, that should keep my utility trailer secure when traveling. Weather covers on key slots are a nice touch. Feel heavy and well made. I'd buy them again. 172497


Comments

Theyve been working great. One thing Ive found that has made a big difference is keeping lock mechanism lubricated. They gave me fits for awhile, as they come with minimal lube I n them, but for easy operation should be liberally oiled inside lock mechanism.

I received the wiring harness last week and put it on yesterday. It works great...no issues at all. I received the Bulldog Lifelong Trigger and Hitch Receiver locks today. They work great and makes me feel more confident when my trailer is sitting in a parking lot for a long period of time. The locks are well made and I don't think you could knock them off with a sledge hammer. Another thing I like about Etrailer is they ship fast. Very satisfied. 363398

When I first received this trailer lockset, the hitch pin lock only locked into position about 10% of the time. I called etrailer and told them about the issue. Their customer service was great and called me the same day to get a better handle on the problem. They shipped a replacement out even before I shipped the defective one back to them. etrailer is a great company and has terrific customer service that personally calls you to follow up on everything. I will definitely be doing business with them on my future needs. 528257

I have had this same lock on my vehicle for several years. It’s a good design in general as it’s not easily snapped off by thieves. That’s why I bought this second lock set for my wife’s new car to prevent her tow ball from being stolen. The only reason I’m not five starring it is that it is difficult to get it to lock. I had to put the key in and turn it left and right multiple times while trying to get the key tumbler to snap down. I would definitely buy it again. 546973

by:

Junk. Coupler lock froze up on second use. Tumbler mechanism is quite flimsy. Phone with customer support and Bulldog said to spray it with WD 40. It was clear to me, with two locks keyed alike in my hand, that one set of tumblers worked properly, and the other was broken internally. This should not happen on second use. If I was on the road, nighttime, tired, small toolkit, trailer locked to tow vehicle, I would have been pissed, to say the least. After a couple of taps of the hammer, the lock popped open and the coupler pin fell out of the lock casting. Cheap Junk! Customer support was very helpful, and offered refund. I'm going back to my trusty old brass Master padlock. 564123

The cap is meant to fit tightly to prevent loss. Id recommend using powdered graphite to lubricate the lock.

E Trailer is a great company. Service is superior! Telephone support is the best-bar none! Please do not let this review reflect poorly on Etrailer. The product identified above is made poorly. Specifically, the key does not fit into the locking mechanism without wiggling or jiggly it to get just the right angle. I don’t believe the company that manufactured this device is at fault either. Unfortunately, you get what you pay for! I’m going to go back to Etrailer and purchase a more suitable locking mechanism. It just isn’t worth using on my travel trailer. As I’ve stated above, do not let this negative review, in anyway, reflect upon the manufacturer and most specifically Etailer!!!!!!!!!!!!! 461118

Piece of junk. After having it on the truck all winter, ended up cutting the rubber cap off and the lock was rusted shut. Spent about an hour with a hammer and pry bar getting the thing out of the receiver. Afraid to use the other one so it's a nice shiny paper weight on my workbench. 314567



- BD580404
by:

This is really an excellent product. I only gave it a 4 star because it lacks the care information needed to keep everything working properly. Has a tendency to rust up and stick after a bit. This is my second set (because I was stupid and drove off without the trigger lock in place). Hopefully, with care, this will last longer. 291821


Comments

Still working well overall. I am noticing some rust and the ball pin is starting to rust up. I need to pry is off with a screwdriver and add a bit of oil. The trigger lock is loose and harder to put together. But otherwise the product is OK. I will ride it out for as long as I can.

We really love the trailer. We did a lot of research and decided this trailer is the most versatile, affordable, and well-built--we were right. We've taken it camping from Texas to Wyoming and have hauled kayaks and used it to haul things like furnature around town. I've also gotten building supplies from Home Depot. I would recommend the longer-neck, much easier to back up with. 279903

I should have listened to all of the negative reviews. This lock set is very poorly built. I was able to unlock both locks by only inserting the key about 1/4 of the way in and turning the key. I bet I could break open the receiver lock with a simple screwdriver. It also came missing both of the rubber caps.....I have similar locks made by Anderson Hitch that are far superior. I do not recommend and will not purchase again. 227659

I bought this so I wouldn't need to add yet another key to my keyring. The good news is the hitch lock is great and much better than the one it replaced. The bad news is the coupler lock is too small for my trailer. The review states it is 3/4 inch and I assumed it would fit but it doesn't. 210631

very sturdy well built locks. will be getting another coupler lock for my other trailer. I won't be worrying about someone walking up popping out a pin and walking away with my hitch while I'm in town shopping or the pin coming out and the hitch pulling out while I'm pulling a trailer. 187066



- BD580404
by:

Great product. I should have read the description a little closer, though. The hitch receiver on my truck is too large for the hitch pin. The hitch pin looks like it was made for a 2 inch receiver. I have a 3 inch receiver with 2 inch adapter. However, the trailer coupler lock fits and works great. The hitch pin size is detailed in the item description, so make sure you get a size that will fit for you. I didn't read the size, so that's my fault. E-trailer had a great price and shipped extremely quickly. 180283

All ok from etrailer..fast shipping with great communication. Just installed products but they are good and heavy so think they will be ok. Locking mechanism seems cheap n nasty so we will see.. There is a lot of trust riding on this simple pin so I would hope it has been tested and built well. 180032

  • Recommendation for Class V Hitch Lock and Coupler Lock
  • There are many hitch receiver sizes available in Class V. For a 2 inch receiver, I recommend the Bulldog Lifelong Trigger-Style Coupler Lock and 2" Trailer Hitch Receiver Lock - Chrome # BD580404 to give you both the hitch lock and the trigger coupler lock. For a 2-1/2 inch receiver, I recommend the Trailer Hitch Receiver Lock - Extra Long - Flush Design for 2-1/2" Trailer Hitches # e98881. For a 3 inch receiver, I recommend the hitch lock # WS05.

Since there is no gauge of how "breakeable" a specific lock is, we recommend making your setup look intimidating to deter would-be thieves. If you are wanting to deter theft of your trailer when it is coupled then the Bulldog # BD580404 is a great option because it has a coupler lock and a ball...
