Types of Hitch Lock

There are several different types of locks available, but the main types are coupler hitch locks and receiver-style hitch locks:

Receiver Style Hitch Lock

A receiver-style hitch lock is the basic entry type of hitch lock and consists of a metal pin that has a lock on each end. This stops would-be thieves from unhitching your caravan and attaching it to their vehicle.

Receiver locks are only useful when your caravan is already hitched to your vehicle. They are almost useless if your caravan is already unhitched, which is why you should never leave your caravan unhitched under any circumstances, especially in areas that it can be easily stolen.

This lock is mainly used when your caravan is being towed, and they are usually made from durable steel which gives it durability and strength.

Coupler Hitch Locks­­

­Coupler locks have a U-shaped design which means it can fit onto the tongue of the trailer which then prevents anyone from hooking up your caravan to their vehicle.

This type of lock also has a ball-shaped top which then is fixed over the ball unit of the trailer, which makes it even harder for a theft to occur.

Coupler hitch locks can still be used even when your caravan is unhitched such as when you have it parked on your driveway without being hitched to a vehicle. This is the ideal solution, and we’d recommend a coupler hitch lock.

Buying Guide

Hitch Size

The hitch size is incredibly important and is just as important as the type of lock that you decide to purchase. If you end up buying a lock that doesn’t fit, then you won’t even be able to use it, making all your pre-purchase research redundant.

Most hitches are universally sized, and won’t fit comfortably on specific models. You first need to measure your hitch size and compare it to the specifications of your chosen hitch lock to check that it’s suitable.

If you can’t measure your hitch, you can just look at the size of your existing hitch lock for guidance.


You should consider the weather conditions that you’ll be using your caravan in before you make a final buying decision. If you’re going to be using your caravan in harsh conditions such as constant wind and rain or very low degrees, then you’ll need a lock that can withstand these types of conditions.

For added protection, you can also use a hitch lock cover to give you added peace of mind that your product is protected.


The material of your lock will go a long way to proving how durable it is. The two main materials that are usually used is either Steel or Aluminium.

Steel is the ideal choice because they are more secure but also means that they will be more expensive. However, Aluminium is lighter, which makes the lock easier to handle, but this also makes it easier to break into.

A thief will find it considerably harder to break into a steel lock compared to an Aluminium lock.


You may be wondering why colour is a buying factor, but it’s quite simple, a brightly coloured hitch lock acts as a deterrent to potential thieves. This means that they can see from afar that you’re using a hitch lock and are unlikely to even get closer and attempt to unhitch your caravan.

Most thieves are opportunistic and want the easiest theft so aren’t going to stick around trying to break through a lock and will move onto finding an easier target. So a hitch lock that’s a bright colour is ideal.

Durability & Life Expectancy

Many locks aren’t able to withstand harsher environments without failing. Cheap locks will quickly begin to corrode, and you’ll realise that the locking mechanism may start to fail due to the low-quality materials.

To avoid this issue, it’s essential to check out customer reviews and the materials that your chosen lock is made from. This will allow you to make a more informed decision. The life expectancy of a lock should be high and you should be needing to replace it every year. 

It’s essential to check if your lock has a water-resistant cap that covers the keyhole as this will protect it from corrosion. A hitch cover will also help to extend its life by keeping it protected.


There are several prominent brands in the caravan hitch lock product space that have been leading the market for several years. They have established themselves with top quality products that are built to last.

The best brands will often have higher price points, but they are made with better quality parts which give you a stronger lock which is less likely for a thieve to successfully break into.


Caravan hitch locks come in a range of prices so you need to have a budget in mind which will help you to make a better buying decision. It’s important to understand that you shouldn’t try to cut corners and just choose the cheapest option.

Many manufacturers pass on lower prices by keeping the production low, but this is often done by using lower-quality materials. These materials may not be strong enough, which means that thieves may find it easier to break into these locks.
