The product is thick enough to deter any theft with the proper dual ratchet lock system.

The name Master Lock impresses me with security locks. I do recommend this combo of latch lock, receiver lock, coupler lock and 2 keys. It’s an affordable solution for trailer owners looking forward to safeguarding their trailers.

Now let’s delve into the buyer’s guide to help you narrow your search. With a plethora of trailer hitch lock abundant in the market, it is not that easy to choose the best right away.
You need to a few aspects first. This need has propelled me to compile this buyer’s guide for you. I will look into the basic definitions of a few terms and the important features you need to know before making purchases.
What Is a Trailer Coupler Lock?
A trailer coupler lock is the tool used to lock the coupler into place to deter any criminal activity on your trailer. Trailers are bought at higher prices and they are very mobile to be attached on vehicles.
As thus, they get stolen so easily and without the proper coupler lock you may find it stolen in a blink of an eye.
A coupler lock is key operated and comes in different designs as evident in my aforementioned products. Some come as the base and the shackle, whereas others, like the gorilla guard above, come in unique designs.
Still on that, others are made with different materials such as aluminum, steel, chrome finish and titanium. But still is the most prevalent metal used because of its toughness and resistance to corrosion and rust.
The coupler locks come also in different sizes. Some fit 2” and others fit over that. You will be fortunate if you found a universal lock that can be adjusted per the hitch. That will save you frustrations and money.
With the coupler lock you can protect lots of valuables from trailers to boats, and campers. The locking mechanism is also different from one lock to the other.
What Is a Locking Hitch Pin?
A locking hitch pin is a locking mechanism that is used to secure the trailers. The pin comes in different sizes for specific hitches. For instance, for Class III trailer hitch with a 2” receiver, a relevant hitch pin is the one with a diameter of 5/8”.
The thicker the diameter of the pin is the more security to your trailer. The hitch pin and the hitch lock are not the same, although their main purpose is to secure the trailers.
Which One Is The Most Secure Coupler Lock?
These coupler locks I reviewed above differ in quality and specifications. A secure coupler lock is the one that can survive all the abuse such as hammer blows.
However, this is dependent on the type of material use. But still is a prominent metal that guarantees security.
Given the whole day or night, a thief can break any coupler lock. Nonetheless, I reckon you consider the material and the design.
From my products above, I recommend the last product; that is the gorilla guard lock. It has a thick steel construction which guarantees security. But I have to admit that it is difficult to have an obvious winner.
Take into account the locking mechanism. Then you might end up siding with the Trimax for its dual ratchet locking system as it also offers a sense of optimal security.
Choosing The Correct Size Trailer Coupler Lock
Choosing the correct size of the trailer coupler lock should be an absolute breeze because you pick based on the ball diameter of your trailer.
So, when choosing, a 2-inch diameter should go with the 2-inch coupler lock and a 2-5/16” with a 2-5/16-inch coupler lock. But, as you choose, note that some universal locks can actually adjust to any size.
It’s advisable to consider this kind of lock if you are unsure about the exact diameter of your hitch ball. Otherwise consult your trailer manual to see the exact specifications.
Features To Look For Before Buying The Coupler Lock
These features are numerous, but let’s consider the durability, design, and ease of use, and the pricing.
Durability is an important factor when buying the coupler locks. The main objective of having the lock is to enhance the security of your trailer. This means durability should be prioritized.
Durability of the coupler lock is reflected by the type of materials being used. Among others, steel and titanium are the strongest metals that are used, but steel is prevalently and predominantly used due to affordability.
Aluminum metal is also used but rarely used alone because its strength is not comparable to that of the steel. Among my products above, there is a composite of aluminum and steel, with aluminum at the base and steel at the locking mechanism.
Chances are, thieves will not be lenient when tampering with your coupler lock. That means you need a durable metal that cannot be broken with ease.
The coating is also important to assess the rust and corrosion resistance of the lock.
Ease of Use
The ease is also an important consideration when buying the coupler lock. This ease of use can be measured by the ease of installation, locking and unlocking. Some have poor locking mechanisms which can be difficult to use.
The gorilla guard above, for instance, it can be challenging to insert the key. However, it is a great product worth having provided you can maneuver your way around the key use.
Others have the auto-lock and release mechanism, while some you need to lock without the keys, etc. Such are good considerations to eliminate the hassle and frustration.
The design of the coupler lock is important too. It is not about an aesthetic look and a functionality of the design. If poorly designed, the thieves can manage to insert some tools to break open the lock with ease.
You need a design that has a 360 degrees protection. I think the size of the lock also plays a part in this. For instance, if the lock is too bigger than the diameter of the hitch ball, it can be to insert a sharp tool and break the lock.
From my products above, you will notice that there are varying designs. Look at the gorilla guard and the Connor trailer hitch lock; they have different designs from the popular U-shackles. Nonetheless, the design alone is hard to figure out if it guarantees the security of the lock.
Also noteworthy to the design is the type of trailer tongue you have. This can be an A-frame, gooseneck or a straight tongue, and it helps in determining the design of the trailer hitch lock. A perfect fit is paramount.
Pricing is just an additional factor but not really of paramount importance as it can be deceptive sometimes. You should typically consider the price of the hitch lock after assessing the aforementioned indispensable features before buying.
But, in some cases, higher prices reflect a great quality. If titanium metal is to be used in a lock, the lock can be more expensive because it is relatively stronger. Aluminum is the least expensive and the least strong metal compared to titanium and steel.
Other Security Systems For Your Trailer
As much as I value the security and importance of trailer hitch locks, I admit that they cannot protect the trailer 100%.
Even the toughest lock can be broken when the thieves have enough time.
This security shortfall necessitates for the inclusion of additional security measures to ensure that your trailer is secured. These include the camera, trackers, and wheel clamps.
The wheel clamps/locks can help combat crime to a higher level. Criminals can maneuver a way around your coupler lock and manage to grab the trailer.
If the wheels are locked, then that’s another frustration to the criminal and the likelihood that he will leave it.
There are wheel clamps such as the Heavy Duty Automotive Anti-Theft Wheel Clamp which is a heavy-duty tool to clamp a wide variety of wheels.
Combining it with the coupler lock can heighten your trailer security. The COOCHEER Car Wheel Lock, Anti-Theft Tire Lock Clamp is also worth considering locking your wheels.
Trailer GPS Tracker
Surely by now every vehicle owners know about the benefits of GPS tracking for the cars. The same technology can be installed on the trailers to help locate them if they got stolen.
This is an indispensable technology to consider if you leave your trailer unattended to for quite a long time.
I have come to the end of my reviews of the best trailer hitch lock on the market. Throughout the journey I reviewed each product in details and highlighted my verdict.
I presented the buyer’s guide which I compiled to help you make the right decision of buying the trailer hitch lock. I have also recommended additional security measures because the coupler alone is insufficient for trailers that are left unattended for a long time.
Enjoy your shopping and always take into account the important features discussed in the buyer’s guide. Do not be deceived by prices. Durability, design, ease of use, and the materials used are important factors to consider.
