  • Read product description below for more information

The renowned American brand of Blaylock specialized in commercial and industrial grade aluminum products, which includes tie down brackets, trailer hitch locks, thief hatches and other types of custom castings.

To begin with, Blaylock is a well-known brand, and this all-American product is made right in the US. With so many of these locks coming from Chinese manufacturers these days, the TL-33 provides real American manufacturing quality.

It is a coupler locking system that doesn’t have a lock and key mechanism. It might seem like it is a disadvantage or flaw to not have this built-in lock. However, the truth is the exact opposite. This system can be combined with whatever lock you want. It has a level of flexibility that not many other hitch locks provide. Couple an expensive padlock with the TL-33 and you will have a system that is most likely more secure than all of the other locks on this list.

All of this security is based on the material used for crafting the lock system. Aircraft-grade aluminum has been used by Blaylock, and this device is rated both for consumer and business use. Aircraft grade aluminum is very sturdy and hard to shatter with bolt cutters or ordinary sledgehammers. A thief would most likely need to have a noisy driller or blowtorch for getting through it.

A really simple design is used by the TL-33 that is easy to play with. This lock system is able to fit on any 2-5/16″ or 2″ couplers. Despite its simple design, this lock looks very bulky and sturdy and can help to deter the casual thief.

There are drilled holes in the TL-33 for the lock to hook through. Not every lock can fit through the holes. Another issue is the overall finish and look. If you enjoy quality workmanship on products you purchase, then you might be disappointed with the TL-33 with its subpar finish and rough edges. The lock does appear imposing and bulky but doesn’t have a premium look.

However, overall, if you are needing your trailer to have the best security, then the Blaylock TL-33 may be the best choice for you. When you choose hte right third-party locks to go with it, you can create a really secure lock system. The quality of the key and lock is left up to you, and that is a really great thing, ultimately.

Pros
  • Rated for both consumer and business use
  • Made in the US
Cons
  • An extra padlock is needed for more security
  • Looks bulky

  • Resists rust and corrosion. Simple installation and removal.
  • Advanced locking mechanism resists picking and prying.
  • We can NOT key two (2) of these locks the same. The similar 379KA...

This Master Lock brand is very well-known in the United States, and has been in use since 1921. During the 1990s, they moved nearly all of the company’s manufacturing to Mexico and China, but some manufactured is still handled at their plant in Milwaukee.

Its all-metal construction and thick coat of paint on top looks good. It clearly stands out when it is installed on trailer couplings. There is some visible deterrence at play.

Since it is a universal lock, you can install it on a broad range of different trailer couplings. This lock has a lot of versatility which can be quite useful when you have multiple trailers inside of your garage. This lock has also been designed in a way that is snugly fits onto couplings of various sizes.

Its deterrence factor is very unimpressive. The lock appears to be very flimsy once it is placed on the coupling. It looks, in fact, like it could be take off with just one clean sledgehammer swing. Although the 389DAT is considered to be a universal lock, when purchasing one you need to check the size of your trailer first. It only properly fits on smaller trailers, and its hitches are rated under 8,000 pounds. It also may not fit on couplers that have flanges that are thicker than average.

The locking mechanism on the product frequently takes time to lock as well as unlock. You might need to spend an extra couple minutes fiddling with it each time. So this lock may not be the best choice if you will be putting on the lock and then taking it off constantly.

Pros
  • Fits snugly
  • Universal lock
Cons
  • Unreliable construction
  • Looks flimsy

Is It Easy To Steal A Trailer?

It’s completely up to you how easy you make it for thieves. For example, if your towable possession (for example a boat on your trailer) is left on your driveway, without having anything like a clamp attached to it, without it pointing in the direction of the road, then you’re definitely asking for trouble.

You should use a clamp if your boat is going to be stored in your driveway for a long time. That won’t stop the thieves still. You also will need to make sure your boat is secured on its trailer in the event they try taking it that way.

If you are using your vehicle to tow and stop for a while, a thief might pounce at a time when you aren’t looking. If there isn’t a two hitch lock installed on your vehicle, then they can just pull up, get your boat disconnected from your vehicle and then place it on their vehicle.

Those are some scary thoughts and there are hundreds of different stories about thefts of this kind happening all over the world. We highly recommend that you invest in trailer security in order to protect your belongings and against heartache that is associated with theft.

What Is A Trailer Hitch Lock Exactly?

A trailer lock is a type of smaller size lock designed to provide your trailer with added protection. It ensures that your trailer is tightly attached to the towing truck. It is used while the trailer is still hooked up to the truck.

Trailer locks are available in many different sizes and designs to ensure that is suits your specific problem ball size on your trailer. After the coupler has enveloped its tow ball, you can the use coupler locks that have keys in order to transport your trailer home. There are various components used to produce locks that are long lasting and resist rust.

Benefits of The Best Trailer Lock

The main purpose of a trailer lock is to secure trailers against theft. After you have installed the lock onto your trailer, usually it will keep it intact so no matter how hard a thief might try to get your trailer unhitched, it will be too hard to so since it provides 360 degrees of protection at all times.

So trying to turn it to a specific angle to take it off will not help you. So the existence of having a shackle is to ensure that a thief won’t have enough time to pick the lock.

The best trailer locks work to prevent the coupler latch from becoming dislodged while you are traveling. Using a trailer lock will help to keep your tow vehicle and trailer in place in case the hitch fails.

Types of Trailer Locks

When we are discussing the subject of trailer locks it isn’t always clear what we are talking about. There are a couple of ways that a trailer can be locked. The following are a few of the most important kinds of trailer locks.

Hoop Lock – This is a common type of trailer hitch lock that is similar to the Reese Lock. It uses a hoop lock design, which is similar to what can be found on a U-lock used for bicycle security or maybe some motorcycle security. The way the products work is through having a ball that fits in the trailer hitch along with a shackle that fastens over the top part of the hitch. The shack can be adjusted so that the lock won’t slip off, so that no one will be able to hook your trailer up without having the key that goes with the lock.

At least that is the hope. Although it is a very popular kind of trailer hitch lock, actually they are mostly ineffective when it comes to providing protection even from very incompetent thieves. We will discuss some of make makes those products so ineffective at defending your trailer against thieves, but it involves the mass production tactics that are used solely for keeping the costs down.

Hitch Pin Lock – There are some people who just secure their hitch pin using a basic spring steel clip. However, there are numerous products that work through more securely locking the hitch pin in place. Some prefer this due to the fact that they trust that this basic spring steel is going to hold up over the long run and they just want to have a fastener that is more secure for their hitch pin. However, there are many people who use the locks as their only type of trailer hitch lock that they use.

If the point on your trailer’s security setup gets removed, then your trailer may be taken away and then the hitch may be reattached onto a different vehicle. I wouldn’t recommend that this kind of trailer hitch lock be the only type of trailer lock that you use. However, there is some security that you can get from it. There are glaring security issues with many products that are mass produced, so if you are planning to use one, it is very important that you obtain the very best hitch pin lock that you can.

Trailer Door Lock – With an enclosed trailer, the thing you need to worry about is somebody taking your whole trailer. The item that is stored inside of the trailer might be a lot more valuable, so if when you don’t have the proper kind of trailer lock on the door, then thieves might target the contents of the trailer instead of the entire trailer.

Service professionals and musicians can have tons of expensive power tools and electronic equipment, which are both quite easy to resell. Frequently the item you are storing inside of an enclosed trailer is intended to be semi-mobile. Therefore, criminals might try unloading the trailer rather than stealing it. The major concern that there is for a trailer lock that you are intending to place on a door is it must be able to lock up against attacks on the shackle, lock body and that hasp that it’s secured to. If you have a high quality padlock it should achieve that.

Trailer Wheel Lock – Ensuring that your trailer stays locked up involves hoping to immobilize it until it is needed. This kind of trailer lock goes around the tire or wheel of a trailer. It is intended to prevent the assembly from getting towed away should any of the other trailer locks become compromised. Many different kinds of trailer wheel locks are available in market, with most of them having weaknesses that are well known, including wheel removal, tire deflation, and pulling.

Utility

In case your trailer doesn’t have a tow hitch lock, anyone can hitch your trailer to their vehicle and take it away in your absence. That is why you need a solid hitch lock for your trailer. Then the potential thief needs to you force to rip the lock off before taking away your trailer. This sort of theft can take some time – which will raise an alarm when spotted by someone. This is the main advantage of a trailer hitch lock. In fact, the overall utility of the lock is based on the following two concepts:

Universal Vs. Deadbolt/Pin Locks

Hitch locks come in two major designs such as the universal and pin or deadbolt lock. The universal lock can fit onto a wide range of trailer couplers. Hence, they are more popular on the market. They come with a metal ball that will fit into the coupler of the trailer. There is a bridge or rod above the ball which is locked to keep the device firmly in place. The coupler sizes may range from 1-7/8, 2, and 2-5/16 inches. These locks are ideal if you have multiple trailers to protect.

The hitch pin or deadbolt lock is designed so that it fits into holes drilled into the couplers. You should have an idea of the exact dimensions of your hitch coupler to buy this type of lock. These locks are usually tighter fitting than universal locks. Hence, they are ideal for RV camping.

In fact, this type of lock will drastically increase the time required by the thief to steal your trailer. This will increase the chances of spotting the theft – which is considered the deterrence aspect.

A hitch lock will offer a varying level of protection depending on the price and quality of the lock. The cheaper steel locks could be easily shattered after a few blows with a sledgehammer. The high-quality locks are much more sturdy since they are made of high-grade steel and aircraft aluminum. These locks aren’t easy to break. In fact, they require blow torches or noisy drillers to break. The longer it takes for the thief to break the hitch lock, the better for the owner of the trailer.

Locking System Options

A trailer hitch lock will come with its locking mechanism built into the device. In fact, you are at the mercy of the manufacturer or brand of the product when you invest in such a lock. In case the locking mechanism fails, you will be stuck with a faulty locking device. That is why you should look for a lock with a protected keyhole. The lock also requires adequate protection from the elements since the trailer will stay outdoors most of the time. In fact, you should look for the best quality lock for the money you spend.

Some of the hitch lock systems are designed so that they can work with third-party disc locks or padlocks. These locks offer a lot of flexibility to the customer. You can buy one of these locks and add to your expensive key system for better protection.
