Sturdy, rustproof lock deters theft of the contents of your enclosed cargo trailer. Cam-and-keeper design, push-button lock, and recessed tumbler provide both security and peace of mind. Can be keyed alike to match other Blaylock push-button locks.

Notes:
After it has been secured, the Blaylock door lock deters the theft of your enclosed trailer's contents. Ideal for enclosed trailers, tractor trailers, and marine shipping containers.
Installation
This lock boasts rugged, corrosion-resistant aluminum construction that is typically used in aircraft applications. The pin that slides through the keeper holes is made of hardened steel. This pin has a pull ring that makes the lock easy to handle and remove when you want access to your cargo. It also acts as a hanger to store the lock when it's not in use. For extra security, the pull ring is designed to break if would-be thieves try to pry the pin out of the assembly.
Of all the options to secure a cargo trailer rear door, this I thought was the best option. So far nothing has changed my mind.
Just what I needed for my trailer. I wish there was one for my side door with the keyed lock as well. Well built.
We purchased a set of 3 in 2014 after our trailer was robbed of $10000 worth of supplies inside. The hasp was twisted off but the padlock was still hanging from the clasp. With the Blaylock covers it is inaccessible. We recently purchased a new trailer and needed another set. We haven't had an issue since 2014! Love this product
need to take more pride in packaging. Put solid ball mount in same box with retail packaged items.
Thank you for prompt exchange on the Blaylock door lock
I just purchased a first class trailer so I wanted the locks to be the same. These exceeded my expectations as did the customer service etrailer provides.
They fit my trailer with some serious effort, but left the latch very loose and wiggly. Not sure if it was my trailer or the lock, eTrailer took them back and the process was easy. They seemed to be of good quality and solid, I just didn't like the way they fit on my trailer latches.
Always a great experience ordering from here!
I just bought a new trailer, needed a extra lock, I have two already and they work great, have had them for several years. No problem at all.

Fine
So far so good. All 3 came keyed the same like I asked. They fit but were just a little loose. So I just added a little self adhesive padding to them and they are perfect.
I will try to review again after I use them for awhile
After my old method of normal pad locks were defeated I started searching for a better way to secure my 20ft cargo trailer. I saw this lock and knew right away, this is the one. I ordered one for each door. They are keyed the same which is a huge plus. So far the locks have kept the honest people out. They look great and have held up to the weather. I'm very happy with my purchase and would definitely buy again if I ever needed to.

This lock is still proforming great. Its holding strong against the weather. Absolutely no problems. It just works!
I really like this lock system. It covers the entire patch area, so you can not access the bolts to undo the door like you could with normal padlocks. I had a good system before but ended up breaking a key in the lock and it was a real pain. I love that these locks have the barrel key, they are so much sturdier and pick proof.
Would highly recommend these locks.

Best lock I have used hands down. Never frozen up or full of dirt from gravel road were lock is gummed up. Would defiantly buy again!
Locks installed easily and look great. Fit is just a bit loose but understandable since these are designed to fit several makes and models of trailers out there. I found by adding a little more padding to the existing padding they snugged up perfectly, in my case. Overall, I would definitely recommend these to anyone looking for that totally covered and secure ramp door bar lock system.

Its been a year now and this lock system is the best. They have worked flawlessly and are really secure and look it as well. They cover all the door latch bolts and dont even rattle when pulling the trailer, at least from what I can hear. Very affordable and did I say d they look great. Highly recommend to anyone looking for that extra bit of security.
Great products and great customer service. Thank you, thank you, thank you... I share your name often. People can't help but notice the trailer door locks I purchased from you a while back.

Perfect, the above average lock simply shows you go the extra to secure your property.
These locks are the best out there. I had my trailer stolen with these locks on. The crook could not break the locks so they cut the door. Great locks. Just need a stronger door!

Excellent locks! Highly recommended
I bought two of these to secure the ramp/door on my 24' Haulmark car hauler. They are well built and are easy to use. Only issue I had was the locking pin was slightly larger than the holes in my trailer door locking arms. Had to drill the holes out a little and now the locks work great. They look very nice on the back of the trailer too!!
LOCK ITSELF WORKS WELL, BUT THE GASKET ON THE LOCK THAT IS THERE TO PROTECT THE TRAILER FINISH HAS CAME OFF AND IS NEED OF A NEW ONE AND THIS IS ON ALL THE LOCKS.
Operates flawlessly. Great customer service too.
I was looking for a secure solution to lock my cargo trailer. Unfortunately, someone pried the factory hasp and riped is right off the door. I was pissed. I did some research and came across these locks. I also found replacement hasps on this website, which I ordered. I got 2 Blaylock locks keyed alike and replacement hasps. After a little tweaking and drilling a few holes, everything works great. Locks fit like a glove. If anyone wants to gain access to my trailer, they will have to cut the door off. Would recommend this product to others.
I first seen your product on another enclosed trailer near my home (I was uncertain what type of look it was). I took a picture of it and found your company on-line. I purchased two locks keyed alike, very happy on ordering, handling, shipping, and quality of device.
Today I was showing your product (My new lock) off to a sub-contractor, he asked "what are you going to lock up Fort Knox"? Even though I have tool insurance, I want to make sure my tools are kept safe.
Thanks for designing a great lock,
Salvatore Cocchiarella
This is by far the best lock on the market! I feel completely safe leaving the trailer, knowing that no one will even attempt to break into it! We purchased four locks for two trailers, and it is awesome that they are all keyed alike. I highly recommend this item!
Good solid product . Just had locks cut off of my trailer so this was my solution . Time will tell , but the lock ( I bought two ) appears bomb proof and made in USA...even better . I would recommend .

A year out , Im very happy with the locks . NO issues , life is good . Still gets my five stars . R.
Very secure lock. Fits well over typical enclosed trailer hasps. Ordered two keyed alike which is great for multiple trailers. Easy to install and remove, best trailer lock I've used.
Awesome product and awesome service from etrailer.com. Had a problem with more doors than locks so I spoke with Preston and my problem was resolved. I was able it order more locks keyed the same as the others so one key does it all. Thank you again Preston for your service.
Product was exactly as advertised. Easy to use, fits great, and thoughtful design details like padding on back side provides protection to painted trailer surface. This is a good solution to a crazy design flaw in enclosed trailer latches: exposed hex fasteners that make it easy for thieves to just remove the lock with a wrench.

I think the lock itself is solid. The one thing I think that could be improved is the rubber self-adhesive pads. The adhesive is not very strong, and the pad falls off. Without the pads you risk scratching your trailer, especially when driving. If you only use the locks when your trailer is parked, its probably not as big of a problem. My solution, I bought some rubber hose, cut some sections about a one inch in length and cut a slit in them length wise. I slid those over the edges of the lock. Problem solved.
