1) Blaylock DL-80 Cargo Trailer Door Lock - Best for Security
The Blaylock DL-80 is designed for enclosed cargo trailers including cargo, vehicle, utility, and tractor-trailers as well as ocean containers. It works on both horizontal and vertical lock rods.
This 7-lb (3.12 kg) lock is made from heavy-duty aircraft aluminum, which is guaranteed not to rust. The lock is a push-button type, and the barrel of the locks are specifically designed to be pick-proof. It conveniently comes with two tubular keys per lock and you can request for the units to be keyed alike.
The lock covers the sides, the top, and the bottom of the trailer door hasp, making it virtually impenetrable, even to sawing. The back of this lock comes with a perimeter gasket to minimize scratching and vibration noise.

Details
- Weight: 7 lbs, 3.12 kg
- Product dimensions (inches): 9" (22.86 cm) x 3" (7.62 cm) x 9" (22.86 cm)
- Handle relief depth (inches): 1 (2.54 cm)
Pros
Cons
What Buyers Like
People absolutely loved the design of the lock, bulky as it may be. The added security measures integrated into this lock are what make the Blaylock DL-80 the top choice for most trailer owners.
Also, the option of having more than two locks keyed alike is especially convenient for trailer owners with multiple locks to attend to.
Final Verdict
The product comes in threes when bought, and on the average, is pricier than the other two on this list. But, if you’re looking for absolute value for top-notch security, this lock is for you.
The downside in buying this lock, however, is it might not fit some hasps, as the handle relief depth, or the cut out where the handle is supposed to go through, measures only an inch. Some buyers have put minimal modifications on this product to address the issue, but overall, it’s best if you measure the dimensions of the hasp and the handle width and depth to make sure that the product is suited for your needs.

2) Master Lock 6271KA - Best for all-around
Puck locks are designed so that the latch is not susceptible to bolt cutters and other devices that might compromise the lock. These are a safer alternative to padlocks, and a cheaper alternative to cargo locks like the Blaylock DL-80.
The Master Lock 6271KA is a puck-style lock made of hardened steel. The body itself is designed to resist bolt cutters. Plus, the shackle is made of boron alloy, which makes it almost impossible to cut, if ever the body is compromised. A dual ball bearing lock mechanism makes it impossible to pry open. It’s also equipped with BumpStop Technology and spool pins, making it extremely difficult to pick.

This lock fits most hasps, even ones on shipping containers. But to be sure, you can check the dimensions of your hasp to see if the lock fits well. If it doesn’t fit, installing a hasp for puck locks might also be a good option, albeit pricey.
Details
- Weight: 2 lb, 0.91 kg
- Product dimensions (inches): 2-7/8" (7.3 cm) diameter
- Lock opening dimensions (inches): 19/32" (1.5 cm) x 1-23/32" (4.4 cm)
- Shackle width (inches): 3/8" (1 cm)
Pros
Cons
What Buyers Like
Most buyers say that this is their choice lock simply because it’s easy to use and is built solid as a rock. The overall design and the layers of built-in security features make this lock superior to padlocks, even ones with shackle protectors. Everyone agreed that this is the best lock to keep their trailers safe.
Final Verdict
Because of its versatility, the Master Lock 6271KA sounds like the smart choice for your trailer door. As with all locks, it’s important to know the exact dimensions of the hasp, to make sure that your product fits snugly. If the Blaylock DL-80 looks intimidating because of its size, this lock will baffle crooks because of the underlying complexity of its mechanism under a seemingly simple design.

3) Trimax THPXL Hockey Puck Internal Shackle Trailer Door Lock - Best for value
The Trimax THPXL is a puck-style lock with almost the same specifications as the Master Lock 6271KA, but the great news about this product is that it’s now on sale on Amazon. Just like the Master Lock, it’s made of steel and is generally weather resistant. It’s easy to use and includes one key. The good news about this is that it’s re-keyable, so you can replace the cylinder and pins. For a slightly more affordable price, you can get the security of a Master Lock.

What Buyers Like
Most buyers were surprised at how they got more value for their money with this lock. Not only does the puck design ward off thieves, it’s also known to be quite sturdy and heavy. Overall, this lock is durable, long-lasting and most of all, affordable.

A little TLC with this lock comes a long way. A single spray with WD-40 should do the trick, if some surface rust begins to appear. But for me, that single extra step is alright, considering the value of this lock. What more can you ask for with this lock? It’s affordable, it’s easy to use, and it’ll keep your trailer and your belongings safe.
