Best Trailer Lock Buyer’s Guide

The Basics

It is easy to say that a hitch lock locks your trailer to your vehicle. But there is more to it than that. Many people think about the thought of keeping your trailer connected to your vehicle while traveling. Sometimes people forget that there is a threat to your trailer even if it isn’t connected to a vehicle.

If you were to leave your trailer sitting in your driveway anyone could drive up, connect your trailer to their vehicle and drive off like they own it. If you have a hitch lock in place you can overcome both of these possibilities.

When we are thinking about these locks we need to consider the idea of deterrence and protection. Most people think a trailer lock overs protection, stopping thieves in their tracks and keeping your trailer completely safe.

The sad truth is that that isn’t the case. A lock only offers a deterrence to a thief. If they are truly set on stealing your trailer and have enough time and supplies they will be able to get through any lock.

One of the things that you are paying for when you purchase one of the top trailer hitch locks is the materials that it is made from. If you purchase a cheap option they tend to be made of low-grade steel. This material can be overcome by a few sharp blows with a sledgehammer.

Higher quality steels won’t be broken so easily. They can still be overcome with tools like a blow torch or angle grinder. This will end up taking longer and being noisier, which is more likely to attract attention.


Design Options

Heavy Duty Receiver LockWhen you come down to it there are two basic models that you can choose from when you are looking to lock your trailer hitch. The first is a universal model and the second is a deadbolt lock. Each has its pluses and minuses.

In a universal model sports a metal ball that can fit into your trailer hitch’s coupler. There is then a bar or bridge or other form of rod that goes over the entire hitch assembly. This means that you can keep anyone from attaching your trailer to their car without a key.

The universal option can work with a large range of couplers. This means that if you work with a lot of trailers you can just work with a single trailer lock.

best Coupler lockThe other option is a deadbolt lock. These are also known as hitch pin locks, since they look like a pin that attaches through the handle of trailer hitch. These tend to be smaller and can be found for a cheaper price.

However, you need to ensure that you have the exact size to match with the hole in your particular trailer hitch. If you have a lot of trailers that you work with you might need a series of these style locks.

On the plus side, this style of lock can be used both while attached or not attached to your vehicle.

If you are really looking for the best option you can always combine the both of them. This will offer you more deterrence to those that might look at taking away your trailer.

However, it will also mean that you will have to keep track of two sets of keys and lock and unlock both sets of trailer locks everything you want to use your trailer.


Considerations – What To Take Into Account When Buying Trailer Hitch?

best receiver lockerWhat are the top three things that go into picking the best trailer hitch lock on the market? It boils down to three simple things.

  • The first is durability. As we have mentioned above a lock needs to be made of a sturdy material. First off, this will keep the lock from being easily broken, as a broken lock doesn’t deter thieves.Also, it has to stand up to the elements. This might not be as important if your trailer is always inside a garage, but most trailers spend some amount of time outside. This means that your trailer and the lock are exposed to the elements and weather.
  • The second major consideration is ease of use. The simple truth is that if you end up with a lock that takes twenty steps to operate, it doesn’t matter if it is the best lock on earth. Most likely you are going to stop using it. And a lock that is not used is a useless lock. You need to find one that is simple enough to use that you feel comfortable doing it in the dark, as there are many times that you could end up being called on to do just that.
  • The final major consideration is compatibility. If you have just one trailer then you can get on that is sized for that. The issue starts coming in if you have a number of trailers or if you are looking to future proof your set up. In these situations, you’ll end up locking yourself into a certain sized trailer or need to go with a universal option to cover a wider range of hitches.

Specifications & Trailer Hitch Classes

One of the first specs that you will look at is the size trailer hitch you are working with. The size trailer hitch you have can dictate the size lock you need. The size of the hitch is dictated by the class of the hitch and the class is based on the weight of the loaded trailer.

There are a lot of sizes to look at when you are considering a hitch lock, but not all of them will affect the lock itself.

trailer hitch classes sizes

The first thing we’ll look at is the class of the trailer. For ease of discussion, we’ll group Class I & Class II together as well as Class III & Class IV. Class V will end up standing alone.

In the first group you have loads no larger than 3,500 pounds, the second group can range all the way up to 12,000 pounds. Class V can hit 18,000 pounds.

You might see a receiver size, the first group will be 1 ¼ x 1 ¼, the second 2 x 2 and finally 2.5 x 2.5. All of these are in inches. These can come in handy if you are looking at a hitch receiver lock.

The next size to look at is that of the trailer ball. These can range from 1 7/8 inches all the way up to 3 inches. For the most part the larger the load the larger the ball. If you are looking for the best hitch coupler lock, these are the sizes that you will be looking at. Sometimes lock companies will group these into two major categories, 1 7/8 into 2 ¼ in and then 2 5/16 into 3 in.


How do Trailer Hitch Locks Work?

As we have mentioned, trailer hitches deter thieves from making off with your precious cargo. This can either be a couple lock that will stop them from attaching your trailer when it is not attached to your vehicle or a receiver lock that can stop them from detaching it from your vehicle and making off with it.

As far as how to use your lock, various models will differ but overall the two main styles can be explained somewhat easily.

For a coupler lock, with your trailer disconnected, you will fit the ball into your trailer hitch coupler. Once it is in place you’ll fit the bar or rod over the hitch assembly and lock it into place. Now you will need the key to unlock it before anyone can attach it to a vehicle.

trailer hitch lock reviewsFor a receiver style lock you’ll make sure that your receiver is in place in your vehicle and then slide the bar through the hole in the receiver and mount. You will then attach the locking side and your receiver is secure.

Some models can also be used in a hole through the engage handle of your hitch, meaning that if you have your trailer attached you’ll have to unlock and remove it before you can release the trailer.

Now, a lock isn’t a total solution. Given enough time and privacy any lock can be defeated, one way or another. If you are concerned for safety there are some other tools you can use along side your pick for the best trailer lock.

The first is wheel locks. These attach to the wheels in a variety of ways and stop them from being able to turn. With these in place even if a thief manages to attach your trailer to their vehicle they won’t be able to drive off (find out more here).

Some people will add in GPS trackers as well, so that if a thief does steal their trailer, they’ll at least know where it is being taken. It is best to conceal these somewhere that a bad guy might not think to look (get one here).

One other option for securing your trailer is adding in a camera set up. You might have a home security set up that features a few cameras that give you a look at your trailer. Why not also put one onto your trailer, it is best to have it aimed right at the coupler. This way successful or not, you’ll have a good look at anyone that has been trying to mess with your gear.

If you end up with something that isn’t quite the right size or not designed to work well with your set up, it could end up breaking while driving which can cause damage to your vehicle as well as damage to other on the road.
