Best Trailer Hitch Lock To Buy [2020] | Review & Buying Guide

Trailer theft has become a piece of a cakewalk for burglary. Over 80% of the trailer theft is because they are left open and without any locks. In just around the USA, there have been over 122 trailer thefts over eight months. Just a few safety standards could have probably reduced the margin. But without them, all of these seem to be never-ending. Every professional working with a trailer does take care of them, but keeping them secure is another important aspect.

A simple lock could improvise the situation and keep the trailer at a safe place. This is where the Trailer Hitch Lock is important to all. Because of the structure and the mechanism, this hitch lock keeps the trailer hitch and the receiver together. As a result of this, the trailer remains locked in a certain position. So even if it is left outside, the trailer is still safe. Most of these hatch locks come with a key that allows hitching and unhitching the trailer.

The coupler lock works with the simple mechanism which includes a bar or a rod over the hitch assembly and a locking ball with the receiver. Once the bar is placed on the lock assembly, the ball comes into a proper place and it activates the lock. The receiver-style hatch is a bit different and it requires a unique accompanying key to ensure the lock is in the correct order. This mechanism is entirely secure and it allows the trailer to lock itself in a certain position.

Frequently Asked Question [FAQs]

Will this work on a lunette ring?

To be fair, lunette rings are different from the ones that the manufacturer provides us. Only a few of the locks will likely be able to fit into the lunette ring. So before you buy one, you need to be specific about the product that you are going to choose.

Can these hitch locks be keyed to our existing Master key numbers?

Every trailer hitch locks are different. Even if you buy from the same manufacturer and the same model, you may find different combinations. This is specifically done to increase the safety levels of the trailer. So they are not designed to be re-keyed. If you lose out on the original keys, you need to contact the manufacturer.

How does the paint hold up, any rush issues?

A lot of people may have the same issues while working throughout. Since it can brush the metallic finish of your trailer front bumper, there are chances that you may lose the paint but it only implies some non-coated locks. If you buy a decent product, the paint will surely hold up and you’re not supposed to collect any rust either.

Will this lock work on a sleeve coupler?

Of course, it can and there will be no issues with a proper sleeve coupler as well. The only thing is that steel locks may be more effective for a sleeve coupler. If it is made up of the polymer, you may not be able to use the horse trailer to this lock.

To help you out with this, you need to turn the key and then hold it in a particular position. Now you can take the bar out.
