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

Guard against trailer theft with this durable steel, butterfly-style coupler lock. Works with most ball couplers that have trigger-style latches. Chrome plating resists corrosion, and the unique ball-bearing locking mechanism provides extra security.The Bulldog Lifelong Trailer Coupler Lock has been a real failure. At this point, it is non-functional. I would describe my trailer usage as moderate duty, such that I would expect a lock to last more than a year. It started failing at about 6 months, increasingly being difficult to get it to actually lock. At this point, I can't even get it to lock!
My bulldog tire pump, on the other hand, has been awesome! Completely reliable, like most of the products I've purchased from etrailer. I would be glad to give it an excellent review. I would be glad to give your company an excellent review. This particular lock, however, is really poor quality. Total waste of money.
I just thought I should tell you directly rather than post a review of this lock. My review of your company overall would be very high, but my review of this particular lock would be 0 stars.
The lock is made to fit tightly which is appropriate for security. Maybe me, however, was too tight to close over my tongue latch and I couldn’t use it.
Worked well but corroded internally quickly unfortunately. Still locked on hitch and can’t be removed without cutting.
broke after 2 months of service. Called for warranty claim - bulldog never responded.
Simple design, dont be fooled, it does the job well, secured trailer in the parking lot with decent lighting. Been on several outfits state travels and I am thankful that the reviews were positive, making my choice to purchase this easier. No issues of it being in open weather with its cover,opens every time. No rust to be found. In all, it provides a level of security for my trailer or at least make it real hard to steal.
All components look like they’re built extremely well and I will be confident leaving my trailer when I head out on vacation this September! Thank you for your help and courteous service!
Purchased a trailer for a move from FL to TX and will be stopping along the way.
I Will have my loaded trailer with me and security where I will be staying along the way is unknown. I looked at many hitch locks with my mechanical engineering viewpoint decided this was an excellent choice. With this lock I will sleep well knowing it is unlikely anyone can unhook my trailer.
It stopped working like 2 weeks after i bought it
The lock is currently being used to secure a metal gate with very tight clearance where most locks do not clear. The attached photo shows the lock installed.
It is very easy on and off. fits well and the rubber cap cover for the key slot is a nice idea. Because it's so compact and fits tightly on the hitch it would be harder for a thief to cut off. It's worth having for the extra feeling of security.
Working as expected.
Substantial!
I purchased this item to use with a 7'x16' trailer which carried my family's household belongings across the country last year. The trailer had a 2-5/16" ball. The reason I mention these dimensions is that this lock didn't fit on my trailer. The shaft was too short for my trailer. I ended up not using a lock and just unhitched and secured the trailer with a coupler lock every night during the trip. I gave this item to a friend who owns a smaller trailer. He loves it.
I watch the Lock Picking Lawyer online, and I see patterns as I watch those videos. I purchased this lock because of the following:
1. The locking shaft is hidden when locked making physical attack more difficult.
2. Hardened steel body construction
3. Disc detainer core which requires special tools and skills to pick.
TLDR; If it fits, I believe you'll be pleased. If you have a larger trailer, it may not fit.
a good quality lock.
Exactly what I was looking for with the cover that goes over the lock
Quick delivery, product as advertised
Good quality product, excellent customer service with this company. I will definitely order from them again!
one star off for heavy plastic zip ties that required saw to cut thru... why make these things so thick you could cut your hand off getting out of the packaging.? Lock fantastically built and engineered. Heavy and very strong. Good job...ditch the zip ties
These locks performed horribly, the three I purchased had all become impossible to unlock and remove from the trailer coupler. I had to cut them off with a grinder/cut-off wheel. That being said, I was delayed hooking up my trailer 45 minutes by the time I got the lock removed. The stainless steel ones I had prior held up great. These were a waste of money.
I own several of these. These coupler locks are good because they require the key to unlock but you can then lock them without the key by pressing the button. They are fairly weather resistant, although the metal pin that goes into the coupler is mild steel and will rust quickly. If that pin were stainless the lock would be improved.
This lock works and performs just like the receiver lock. The ball bearings will need a slight coating of grease to keep things moving over the long haul. I only wish this was made in Stainless Steel to match the other lock. Having just received this, I will update in the future if any problems appear. Extremely happy with speed of delivery and availability of these locks.
I got two of these since I needed locks on two trailers. They function differently than similar locks I have used in the past. The lock is a plunger type that uses the key to press in and lock it shut.
Both of the locks required a lot of wiggling and turning to get to lock. They appear to have crude tolerances and a lot of play, requiring exact lining up to close. I put a little lube in the lock and ball mechanism and it helped. I was not able to pull them apart by hand once locked. They do unlock easily with the key.
I know they aren't the best quality by the price I paid and they are made in China. I am tempted to pry or hammer on one a bit to see if it opens. If it does, I will just chalk it up to knowing better than buying cheap and replace both with higher quality locks. If it holds up, I will say I got my money's worth.
E-Trailer does have excellent communication regarding sales and shipment. I have bought from them in the past and will in the future, no matter what the final verdict is on these particular locks.
Purchased two trailer coupler locks for a new travel trailer. The locks arrived in 5 days and were exactly as described. This is my first purchase with 'etrailer.com'. I am sure there will be more purchases in the future. Nice site and easy to navigate.
Lock shackle too short to use on my trailer. I'll try to find use for it somewhere.
