Trailer Hitch Lock Buying Guide

As you see, each option on the review list offers a specific set of features to go for. They are all worth considering, but only some features will really matter in the long run. Here, we’ll explain all these factors and how they matter:

Hitch Size

First of all, consider the hitch size. Not all locks will fit all trailers or RVs. And for that, you’ll have to go over the different coupler sizes available out there. You will find sizes going from 1-inch up to 1-7/8-inch, going over 2-inch, and even 2-5/16-inch.

Before you go and buy one lock, make sure you know precisely what hitch size your trailer comes with. Then, you can pick the lock accordingly. Be aware that some models only fit one or two hitch sizes, while others may fit all of them without problems.

You’ll want something versatile, but that doesn’t hinder safety. So if you can go for something that fits your coupler size specifically, then that would be the best choice.

Key Combination

Not many people care about this – but it can make a huge difference. The key matters because anyone could break in a simple lock combination. But not everyone can unlock a complicated combination.

To make sure that the lock you’re going for offers to go for keyholes with unconventional sizes & combinations. This way, you can ensure a much more secure lock that no one can break-in.

Apart from that, go for those models that affirm having hundreds or thousands of key combinations. That will keep the safety of the key even higher. So no one with a similar key will be able to open it.

Build Quality

When we talk about the build, we talk about the sturdiness it offers. This has a lot to do with the right materials, as well as the design. Some models come with high-end components that will prevent any type of picking or prying. But others will not.

You must always consider the ones that look more sturdy and difficult to break or open. In the long run, those that look sturdier are the ones that handle more years of use. And sure enough, they’re also the ones that won’t break easily.


If you want the best trailer coupler lock, you will undoubtedly need to choose the right materials. Otherwise, you’ll end up with a product that either breaks too fast or doesn’t stand the weight of time. Here are three materials you’ll find:


This is an excellent option as it handles corrosion well and resists shocks and impacts. Breaking a steel lock is not an easy job – and even with fire tools, it can be pretty hard.


Aluminum is another ideal material to consider. It is not as resistant to impacts and shocks as steel, but it can still handle several years of use.


Similar to steel, this material is super strong and resists impacts like no other. Breaking iron can be almost impossible. But iron tends to rust faster – so it may end up being a bad choice over the long run.


Finally, you will find a rubber. This is not the most common choice – but it is still useful if you want something cheap. It won’t keep people from stealing your RV, but it can be truly difficult to break still.

Easy to Use or Not

Nothing compares to an easy-to-use lock. That saves time and effort, especially if you care about storing your RV in the quietest or fastest way possible.

That’s why we always recommend simple mechanisms. They may seem simple for thieves to break, but they are just as difficult or even more than any other models to open. And sure enough, they won’t give you a headache when using it.

Lock Design

After considering whether a lock is easy to use or not, then you need to make sure that it is perfect for your trailer hitch.

This is not about size but about the design. There are different kinds of couplers out there, going from ball-headed hitches, open hitches, and traditional ones. You must ensure that the lock you pick fits precisely that kind of coupler.

To make this a piece of cake, you can go for versatile models that fit all kinds of hitches. Some locks are so fantastic that you can pair them up with any type of hitch, and they will work the same way in all of them.


Compatibility is essential, and style is too. You want something versatile, but you also want a lock that tells thieves they’re present. That’s why we always recommend users to go for models with bright colors like red or yellow. These are often ideal for keeping robbers away in the first place.

But if you go for a black, gray, or something that doesn’t look like a lock – then it is likely thieves will still get close and try breaking it. With bright colors, this has a smaller chance of happening.


This is one of the hardest things to consider. Price differs exponentially depending on the number of features, type of construction, materials, and style.

For us, an expensive model won’t necessarily mean that it is better. But the price will undoubtedly put more features and better build on it than an affordable one. Go for something that matches your needs but also fits your budget.
