The 10 Best Trailer Locks of 2023

A trailer lock is a device designed to secure a trailer from being towed away by unauthorized individuals. It is typically a heavy-duty lock that attaches to the trailer’s hitch, preventing the hitch from being connected to a towing vehicle. Trailer locks come in various designs and styles, but the most common types are coupler locks, wheel locks, and kingpin locks.

If you own a trailer, the first accessory you want to invest in is a quality trailer hitch lock. Unfortunately, trailers are often sought out by thieves since they’re relatively straightforward to steal and easy to sell once stolen. In addition, stolen trailers have a low rate of being recovered. Even if they are found, there’s a good chance all the stuff stored inside is gone. A trailer lock is a small investment that could potentially save you a lot of headaches and heartache down the road. After all, the money spent on a trailer lock will be less than the cost of replacing a whole trailer.

Fit: This lock fit snugly over the receiver and was able to secure a tight fit thanks to its thick steel arm. The hitch ball was still slightly too small.

Feature

The CZC AUTO coupler lock is a heavy duty lock, despite its size. This model seems to be the best trailer tongue lock when it comes to corrosion resistance.

3.8

Pros

  • Comes at a small size for portability
  • Doesn’t rust quickly due to a lack of ferrous metals
  • The round key works smoothly without any hurdles
  • Comes with unique keys to avoid duplication from other people
  • Locks securely into the trailer’s keyhole

Cons

  • Slightly annoying to turn the key seven times

This coupler lock is developed from durable steel to withstand prying or any robbery attempts. It feels quite heavy duty and looks neat with its black chrome finish. Additionally, the lock isn’t keyed the same, so you can rest assured that no one can access it.

I tried to test whether this lock is prone to corrosion. Pleasantly, this lock doesn’t contain any ferrous metals because there’s no attraction between the lock and the magnet. Also, I have to appreciate the round key because it’s very robust and works smoothly.

I’ve noticed that the locking bar fits just right to the trailer’s hole. Once the in and the keyhole are aligned, you just turn the key about 5-7 times to close. For me, I find this mechanism better than the ones you need to push to lock.However, this coupler hitch lock takes too long to lock and unlock as you have to turn the key 5-7 times. It’s a bit annoying if you’re in a hurry.

  • Provides convenience as all locks are keyed similarly
  • The bright yellow color serves as an excellent visual deterrent
  • Comes with a swiveling clip for easy replacement of cotter pins
  • Has a reasonable price and a 1-year warranty

Cons

  • The coupler lock and hitch pin are a bit weak

The set consists of a brass coupler lock, a universal coupler lock, and a dual bent pin receiver lock. My favorite is the dual bent pin receiver lock because it fits on my ½-inch receiver very well.The bright yellow color is an excellent idea because it discourages thieves from prying on the receiver lock. Besides, this lock fits nicely on my 2-inch hitch, and it seems sturdy. I think the lock is made of forged steel, which is usually more rigid than steel.

The best part is the kit includes a swiveling clip, so it’s easy to replace the cotter pins. Additionally, this kit offers great value as it provides three types of locks at one price. Best of all, it comes with a one-year warranty for incredible ease of mind, which is a nice upgrade from my Motormic trailer hitch lock pin set.My only dismay is that the coupler lock is a bit flimsy. The hitch pin is also slightly wimpy because it can break with a good hammer.

What To Know Before Buying Trailer Hitch Locks

Buying a lock for your trailer needs careful consideration because the trailer’s safety depends on that little equipment. It’s not enough to look at the trailer hitch lock at face value. You have to make sure that it fits all your specific needs.

The Different Types Of Trailer Hitch Locks

Like all other products, hitch locks aren’t made the same. They come in various forms, but they serve the same purpose, and that’s to keep your trailer from being stolen. Here are the various trailer locks that you should consider when looking for the right one.

Receiver Hitch Locks

The receiver hitch lock fits crosswise into your towing vehicle’s receiver hole. These locks are perfect for securing your hitch trailers, so they can’t be taken out without a key.Basically, these are metal pins with locks on the edges. Some of these receiver hitch locks have two locks on the side, while others have a crooked end to prevent being pulled out.

Coupler Hitch Locks

With a design that’s similar to a U-lock that you find for bicycle security, coupler locks are popular in preventing unwanted hitching. These locks usually come with a ball and shackle to help secure the hitch over the top. Frequently, the shack is adjustable to make sure that the lock won’t get loose.

Hitch Pin Locks

A trailer hitch pin lock uses the basic spring steel clip to keep the hitch pin secured. However, many models reinforce protection with more developed features. I prefer the basic model because it’s good enough to keep the hitch pin secure and hold up for very long.However, this kind of lock might get taken away easily and reattach to another vehicle. I suggest using a visual deterrent hitch pin lock to deter thieves from messing with your belongings.

Benefits And Drawbacks Of Trailer Hitch Locks

The main benefit of a hitch lock is to protect your trailer from thieves when you’re away. A hitch lock binds the receiver and the trailer hitch together. The coupling can only be broken when you unlock it with the designated key.

After you have set this lock onto your trailer, it will be hard for the thief to lift the receiver and run with your trailer. The best locks are even impenetrable from any torture. If you want to ensure that a thief won’t break into your lock, attach a shackle.

Besides security from thieves, a trailer hitch lock also ensures that your coupler latch won’t get dislodge while traveling. It keeps your trailer and tow vehicle from wobbling and creating a rattling noise.However, some locks can get mutilated with the right equipment. Experts can pick on the lock or even beat it with a strong hammer. To achieve the best protection, look for durability and robust locking mechanisms.

What To Look For On A Good Trailer Hitch Lock

Of course, your trailer’s security depends on the hitch lock. To make sure that you have made the right purchase decision, here are certain things that you might want to consider.

Design Fit

For hitch locks, you have to choose between two designs: universal or deadbolt. Universal locks are more versatile as they can fit a variety of coupler styles and brands. These locks often have a metal ball to fit the trailer and a bridge above the ball to keep the equipment securely in place.

Universal locks often fit with coupler sizes 1-⅞”, 2”, and 2-5/16”. These models are perfect if you own multiple trailers or plan to use a different trailer.Also known as deadbolt locks, hitch pins are made in a way that they fit into the coupler’s drilled holes. These locks usually give a tighter fitting than their universal counterparts; hence they’re more famous for RV camping. Since these locks will be bolted onto your coupler, get the exact dimensions.

Locking System

If you want your lock to be impenetrable from picking and prying, look for a lock with a formidable locking system. A barbell locking mechanism makes the lock fit more snugly into your hitch, adding another layer of security. For ease of use, look for a push-button lock mechanism.Some of the best hitch lock systems allow a third-party padlock to provide more flexibility. For example, Blaylock TL-33 enables you to use a padlock to reinforce the lock.

Rubber Lid/Cap

You want your locking mechanism to always perform at its best, or you’ll end up with faulty locking equipment. To protect your locking mechanism, look for a rubber lid to cover the keyhole. The rubber lid will protect the lock from dust, rain, and other elements that might damage the inner parts.

Material

You’ll want the lock to be as robust as possible so that it can endure any hard beating. The best locks are made of hard steel and aluminum. They often have come with a corrosion-resistant zinc or chrome finish to extend the life of the lock.

Visibility

An effective way to deter a thief from his evil plans is to get a visible trailer hitch lock. Look for bright colors as they’re easily visible, plus they give a nice aesthetic to your trailer. The most popular colors used are yellow and red.

Warranty

An extended warranty is a great assurance that the lock can last for a long time. The longer the warranty, the more durable a product seems to be. Most hitch locks offer the basic 1-year warranty, while the top-rated ones provide a lifetime warranty.

What is a Hitch or Trailer Lock?

As their name suggests, a hitch or trailer lock is designed to keep your trailer from getting stolen. A hitch lock is a product that keeps your trailer hitch and receiver together, with the lock preventing someone from lifting the receiver. This ensures that a thief isn’t able to unhitch the trailer unless the lock is off.

A trailer lock, also known as a coupler lock, keeps your trailer safe when it’s unhitched from your vehicle. Without a coupler lock, someone can simply drive up to your trailer, hitch it, and drive off. These locks fit over the coupler on the trailer’s tongue, preventing someone from hooking up their vehicle and driving off.

Essentially, a hitch or trailer lock plays the role of an insurance policy. Without one of these locks, a savvy thief can drive off with your trailer in a matter of minutes, if not seconds. Unfortunately there is no such thing as a lock that will completely prevent a thief from stealing your property if they want it badly enough and have the time to break off the lock. But locks do serve as a deterrent and some may cause enough of a struggle that the thief gives up.

Trailer lock type

Trailer locks come in a variety of types, but some common types include:

  • Hitch lock: This type of lock is designed to fit over the hitch ball of a trailer to prevent someone from hitching the trailer to their vehicle and stealing it.
  • Coupler lock: This type of lock is designed to fit onto the coupler of a trailer, which is the mechanism that attaches the trailer to the towing vehicle. Coupler locks prevent the coupler from being opened, which prevents the trailer from being unhitched.
  • Wheel lock: This type of lock fits onto the wheel of the trailer and prevents it from turning, making it impossible to tow the trailer away.
  • Kingpin lock: This type of lock is designed for fifth-wheel trailers and fits over the kingpin, which is the part that connects the trailer to the towing vehicle.
  • Glad hand lock: This type of lock is used to secure the air brake connections on a trailer, making it impossible for the trailer to be moved without the lock being removed.

The type of trailer lock you need will depend on the type of trailer you have and your specific security needs. It’s important to choose a lock that fits your trailer properly and is made of high-quality materials to ensure it provides the level of security you need.

Trailer locks offer several advantages, but they also have some disadvantages. Here are some of the key advantages and disadvantages of trailer locks:

  • False Sense of Security: Trailer locks can provide a false sense of security, leading you to believe that your trailer is completely safe from theft. However, it’s important to remember that no security measure can guarantee 100% protection.
  • Inconvenience: Some trailer locks can be inconvenient to use, requiring you to spend extra time hitching and unhitching your trailer. Additionally, some locks may need to be removed before you can tow your trailer, which can be time-consuming.
  • Compatibility: Trailer locks may not be compatible with all types of trailers, and you may need to purchase a specific type of lock for your trailer. Additionally, some locks may not fit properly or may be difficult to use with certain types of trailers.

Fundamentally, a lock fits tightly over the hitch ball to prevent the hitch from getting stolen.
