A locking hitch pin provides an extra layer of security to keep your trailer attached to your towing vehicle. Similar to a U-lock for a bicycle, it fits into the receiver hitch fastener and requires a unique key to unlock.

Look for a lock with features that enhance its visibility and deter tampering. It should also be easy to install and compatible with most standard receiver hitches and ball mounts.


A locking hitch pin prevents a trailer from being unattached from a vehicle, whether empty or fully loaded. It works by sliding into the hole in your receiver hitch where it fits and then locking it with a head or a clip.

Several lock systems are available to fit your trailer’s receiver hitch. The most popular is a receiver-lock pin with a head that fits into the hitch hole and then locks into place with a key.

Some models also have dual locking pins that prevent the ball mount from detaching from the hitch receiver. This adds an extra layer of security and helps to minimize theft and other accidents or mistakes that can be made on the road. These are the most secure hitch locks, mainly if you use your trailer to transport cargo or equipment.


When used correctly, a locking hitch pin helps prevent theft of your trailer and any attached cargo. It works by sliding into the fastener hole of your receiver hitch to secure it. If someone tries to pull the pin, they will find it difficult or impossible to remove it without a tool because of the lock’s construction.

If you’re looking for extra security, try a dual-locking hitch pin. It features a triple ball insert that blocks the hitch ball from coupling to the trailer, and it has a bright orange finish to deter thieves. It also includes a rubber debris cap to protect the keyhole opening from moisture, dirt, and rust.

Another option is the forged steel right-angle locking hitch pin. It has a threaded design to help provide anti-wobble for your hitch-mounted accessories and comes with two keys. It’s made of stainless steel for durability and corrosion resistance in any weather, including snow, rain, ice, and mud.

Using a locking hitch pin gives you the peace of mind that your hitch-mounted accessories are secure. It also ensures you can use them without worrying about someone pulling off your trailer hitch and cargo carrier while you’re not looking.

Besides being useful as an anti-theft tool, these locks benefit your towing safety by increasing stability. They prevent your ball mount from moving around or shifting underneath the coupler. This reduces the risk of swaying and fishtailing, which can lead to severe accidents on the road.

Look for a lock that has a high-quality design, such as a cylinder that prevents lock picking and rust protection. You can also opt for a lock with a protective cover to absorb impact damage from hammers and crowbars.

Lastly, choose a lock with a convenient keyhole that is easy to use. You should only need to insert the key and turn or rotate it in the direction specified by the manufacturer to unlock it.

Ease of Installation

Whether you’re a trailer owner or just considering getting one, it’s a comfort to know that your rig won’t be easily removed when it’s not attached to your vehicle. That’s why hitchpin locks are a welcome solution to many people. They ensure that your trailer isn’t stolen and minimize the risk of an accidental detachment while on the road.

The most essential step in utilizing a hitch lock is to follow the proper installation procedure. That starts by inspecting the receiver to ensure it’s securely inserted and perfectly aligned with the shank of the trailer hitch.

Once that is done, you can move to the next step and install the lock itself. The process for doing so is simple. It just involves inserting the key into the lock and turning it as the manufacturer’s instructions indicate. It would help if you stored the keys somewhere safe but easily accessible.
