What Is A Trailer Hitch Lock/ How Does It Work


This product is a special RV lock designed to deter and stop criminals and thieves from making off with your vehicle. It can keep the receiver and trailer hitch securely together unless you unlocked it using its key.

The hitch lock can stop a thief or someone from lifting your receiver without the key. For this reason, this person will not be able to unhitch you RV and flee with your trailer by hitching it on their truck.

However, take note that the lock isn’t the only thing you need to keep someone from stealing your trailer.

You also need to make sure that you do certain practices that will prevent your trailer from being stolen. We’re going to discuss a few pointers on this later.

How does it work? The theft deterrent device would stop thieves from stealing or trying to steal your trailer.

The way that they work will depend on the type of lock you’re buying.

The coupler lock needs you to disconnect your trailer before fitting the ball into the coupler of the trailer hitch.

On the other hand, the receiver style lock is different and functions around the receiver of your vehicle. But before using the lock, you need to ensure that your receiver is in place. By installing the lock correctly, you’ll be able to secure your trailer and keep it safe from theft.

It is how simply the lock works in keeping your vehicle safe. While there can be other models on the market, the two types are the most common because they’re not complicated to use.

So if you would like to keep your trailer protected and safe especially in storage or when unattended, you should have a hitch lock to keep it secured.

Types Of Trailer Hitch Locks


Before adding a product like a Master Lock trailer hitch lock into your cart, you can help yourself by knowing the types available on the market.

In the following, let’s talk about the types of trailer hitch locks to choose from and use for your trailer.

Coupler hitch lock

This device can protect your vehicle when it’s unattended in your driveway because it is unhitched. Commonly, it is a U shaped lock that can fit in place over the coupler located on the tongue of your vehicle, giving a thief a hard time to steal the trailer and hitch it onto their truck.

In general, the lock has a ball shaped top that goes to the place where the ball unit on the towing truck would be placed into the coupler. For this reason, it will be difficult for a person to hitch the trailer onto their vehicle.

Receiver style lock

If you’d look at it closely, the product is a metal pin that comes with locks on its ends. There are some models with two locks on either ends, while the rest usually have a curved end, making it incredibly hard for someone to pull them out. Any of the design works effectively in keeping a thief from stealing your vehicle.

In general, the hitch locks have the purpose of protecting the trailer from thieves when it is in the driveway, in storage or unattended.

However, make sure that you aren’t unhitching in a place where the trailer can be stolen easily. As remember, the locks will render useless once your vehicle is unhitched.

Nevertheless, the lock will keep your trailer from being stolen. It is a valuable investment to have especially if you want to store your trailer. You might want to consider one of the options reviewed above for a trailer hitch lock now.

Benefits Of Using A Trailer Hitch Lock

Many trailer owners say that the best way to lock a trailer is to use a hitch lock that will keep the trailer safe and protected especially when in storage. Without the device, you might not be able to protect your trailer from thieves who may be thinking that stealing your trailer is a great idea.

If you don’t want to be a victim of thieves, you should definitely invest on a trailer hitch lock, which is a must-have device in your trailer.

In addition, the product is also useful and versatile because it can be used for other towable vehicles like RVs well as boats, bikes and jet skis. As you may know, these are precious investments. You can take care of them using a great hitch lock.

Using a trailer hitch lock, you can have some protection versus a criminal or someone who might also be trying to steal the trailer. With it, this person will have a difficult time in hitching your trailer onto their truck before going away with it.

You’ll be surprised how these amazingly affordable locks are working wonders to keep your trailer protected and safe. Using it, you can have peace of mind and sleep well at night, knowing your vehicle is safe in place.

These products are reasonably priced even the top quality ones that we have reviewed earlier. For help in picking the right lock, keep reading in the following section for the factors to check when finding a hitch lock for your trailer.

How We Picked


Just like any other RV accessories and products you’re buying, your choice of hitch lock should be with much attention and care, too, because there are many of them on the market that might confuse and make it hard for you to choose one.

In the following, let us help you pick the right hitch lock for your trailer so that you can start protecting your precious investment especially when it is unhitched from your truck.


It has to do with the heavy-duty performance of the lock. In this case, you might want to find a lock with durable materials. For example, it is a good idea to look for those made from hardened steel.

Such material can ensure that you’re getting a tough product that will make a thief think a couple of times whether or not they’re going to steal your trailer.

On the other hand, there are also products made from aluminum, a lighter weight material than hardened steel. However, it might be less secured and easier to bypass.

So without even saying, those made from aluminum can be an easier target for thieves.


To compare your options well, should also check into the lock design. There are some manufacturers that sell locks with keys that can be used for their other products.

You can just imagine how a safety threat this situation could be. A criminal with the key similar to the design of yours can easily unlock and steal your trailer.

The good thing is that there are hitch lock manufacturers that design and create locks with a unique key. I would surely go for this option. There is no way I would buy a lock with a key design similar to what others have.

Coupler size

A hitch is classified into classes just like vehicles, from class I-V. From that, you can conclude that not all types/size of hitch locks will support all classes.

For instance, make sure that your hitch is going to work well with ½ or ⅝” pins, which are common among receiver locks. Now if you have a class III-V hitch, you might have to go for ⅝” pin lock.

Not getting the right size, you will have a hard time locking your travel trailer. You need to ensure that the lock you’re buying will fit based on your hitch size and requirements.

In addition, you must determine the receiver size on your camper, trailer, recreational vehicle or boat.

Then, you also have to check that it matches the lock you’re eyeing to buy, ensuring it will match your hitch’s specific needs, or else, you would end up buying a useless lock. More so, it will be a great idea to figure out the correct coupler size to find the one to fit your needs.

To prevent buying the wrong product, you should first determine the size you need. For some help, you might also want to read the product description or reviews thoroughly to ensure you’re getting the correct lock for your needs.

Other features

When shopping around for a hitch lock like a tongue lock for trailer, you might also want to check on other features.

For instance, check on powder coating finishing that will protect the lock from the elements and rust.

You can consider products that can deal with the worst weathers to keep them from rusting faster.

So if you live in a rainy climate area, you must check that the product that you’re buying can deal with the condition. Also, you might want to read on customer reviews to ensure that the locks you’re buying have such features.

More so, it would help to find product with waterproof features. For example, it should have a waterproof cap on its keyhole to reduce its chances of rust formation.

There you have some of the things to look for when finding a good hitch lock for your trailer. Keep them in mind and be sure to refer to this buying guide for help in comparing your choices.
