How to Lock a Trailer so it Cant be Stolen? Plus 9 Anti-theft Tips


We all work hard for the items we own and do not want them to fall into the wrong hands (dun dun dun….) With the right amount of effort, anything can be stolen.

My wife and I always have our feelers out when it comes to protecting what we own and preventing anyone from stealing our items as we have been stolen from in the past, and its not a good feeling. It would be the worst to be out in the middle of nowhere and come back from a hike and find out your generator, trailer hitch, or whole trailer itself is gone. We go over RV and trailer anti theft devices, interior security as well as the security of your items when out camping.

How to lock a trailer so it can’t be stolen? The best way to protect your trailer from theft is to leave it hitched up to your vehicle, someone would have to steal your vehicle or move it in order to steal your trailer. The next best way is a hitch coupler lock. Locking your coupler will ensure no one can hook up and be off with your trailer.

Complete Guide to Securing your Trailer

Below, we detail the best trailer anti theft devices available on the market today. With one of these, or a combination of all, your trailer will keep out of the clutches of anyone looking to take it.

Best Trailer Anti Theft Devices

The items below will help keep your trailer secure from theft of the trailer itself, the hitch, or items within the trailer. There are several ways to protect your belongings, but you may also want to use several of these tactics.

Hitch Coupler Lock

The best way to prevent someone from stealing your trailer is to prevent them from hitching up to it in the first place. Whether you are out on a camping trip, or your trailer is parked in storage, it is best to always keep it locked up so no one else will have access to moving your trailer without your knowledge.

There are several different designs of hitch coupler locks, but we have found this model to be our favorite. It not only protects the couple from having a ball inserted but rounds the front so cutting this off would be quite hard.

This coupler lock attaches to your coupler just like your trailer hitch ball does and locks into place. A thief would create quite a bit of noise if they had to grind or try to remove this from a hitch, so they should get caught before they are successful.

Hitch Pin Lock

We use a hitch pin lock with our hitch coupler lock which keeps the coupler locked so it would be impossible to fit the ball in making it unable to be connected. We also keep this lock on every time we tow just in case a pesky kid comes and flips the coupler up. This would not be the best thing to happen while you are towing down the road at 60 mph. It is always recommended to have a pin in the hitch coupler so it does not wiggle loose, and this device will take its place and keep it locked on to whatever it is hitched to.

X-Chock Locks

Whenever we are parked we install our X-Chocks to keep our trailer stable when we are walking around. The design of the X-Chocks puts pressure against the tires if you have a dual axle which prevents them from moving.

We then insert a cable lock to lock the X Chock to our wheels creating another way for the trailer to not move. Someone would have to cut your wire lock and remove your X Chocks in order to move your trailer. This is yet another layer of security to prevent your trailer from being towed away.

Read more about our X-Chocks on our article on the best wheel chocks.

Wheel Chock Lock

A wheel chock lock is another device that could be added to your travel trailer, rv, automobile, or anything on wheels to keep it from being stolen.

This is similar to the boot, where it goes around your tire and wheel and locks it in place. This works great as the unit cannot be towed, and this device would be very hard to tamper with and remove without damaging a tire or anything else.

GPS Tracking System

GPS tracking systems have been available for vehicles for a long time now. This is not necessarily an anti-theft device, but if your trailer does end up stolen, you can point police in the right direction to its whereabouts. This device could be hidden inside the trailer or under the undercarriage. Either way, this will leave you able to track its every movement.

How to Secure the interior of your Travel Trailer

We have gone over the external items on how to keep your actual whole trailer from being stolen, but now let’s look into how to protect the items within your trailer from being tampered with or stolen.

Replace Hatch Locks

Many of the locks on travel trailers are keyed alike. The hatch lock keys may be the same as your neighbors with the same brand, or even a different one. These locks are usually very weak and can be picked easily.

It is recommended to replace your hatch locks with aftermarket locks that your neighbor will not have a key to. These locks can be replaced with combination locks that allow you to set your own combination, or with a different lock which includes a different kind of key for added security.

Hatch locks are very easy to replace, so leaving the factory locks on can be a mistake that could leave you out of many of your supplies or even a generator.

Electronic Door Lock

The door lock on your travel trailer may suffer from the same issue as your hatch locks. Anyone with that same kind of trailer may have a key. It is a good idea to replace your door lock as well when you are securing up your RV.

An upgraded electronic lock with pass code is wonderful as if you are hiking and misplace your keys, or go swimming and want to leave your keys in your trailer, this electronic lock allows you to do so. Our favorite keypad lock allows you to create your own combination and lock and unlock on the fly as well as has a key fob to lock and unlock remotely.

How to Lock your Travel Trailer Accessories

Lock your Expensive Batteries

Whether you have lithium or lead acid batteries on your travel trailer, they are expensive to replace. Lead acid can cost upwards of $300 to replace and lithium can cost upwards of $800. One thing you will want to make sure is locked up is your batteries

Coming to your trailer storage unit to find your batteries are gone is not a fun sight. This genius invention can save your batteries from becoming a target for a thief. It is available for single or dual batteries depending on how many batteries you have.

It is fairly simple to install, but provides great protection.

Secure a Generator

The generator you pack along on your camping trips is often one of the most stolen items. We recommend you lock it up to your ladder, frame, stairs, hitch, or anything you can fasten it to. As these units are becoming smaller and more lightweight, they have become easier targets.

A generator can range from $500 to $1,000+ so taking the added security is cheap insurance. We use a cable bike lock as well as a lock to fasten our generator’s handle to our rear bumper. Now at the end of the day, someone could still steal this with minimal tools, but at least it makes it apparent you are protecting your items and makes it a little more difficult for someone to steal.

Lock your Surge Protector

A surge protector is such a small item that can be stolen at the blink of an eye, you want to make sure it is locked up. Our favorite surge protector comes with an eye loop to enable it to be locked up with a simple cable lock. This can be a quick way to save your 100+ surge protector with minimal time.

Propane Tank Lock

By locking up your propane tank(s) you will prevent them from being stolen. They can be expensive to not only replace but if you have them full of propane, there is even more lost cost.

Keep your Weight Distribution Hitch Locked

We have made friends with others at many campgrounds and have listened to many horror stories. This one, in particular, must have been very hard. The couple we had met had left the campground hiking for the day and left their hitch attached to their truck.

Upon return, their expensive weight distribution hitch was gone. Not only did this cause them to purchase another hitch, but their campsite was 3 hours away from the nearest town with one. Their specific brand was not available from the two trailer stores, so they had to opt-out of a weight-distribution  hitch and go with a normal one.

Towing their massive trailer with no weight distribution or sway control was horrible for them. Once they got back from their summer trip they still had to purchase a new weight distribution hitch. This small event of a 6 hour drive, $400 for a new hitch, and all the hassle could have been prevented with a sub $10 item.

We recommend this hitch lock to lock your hitch to your car’s receiver so it does not walk away. We also recommend storing your hitch in your trailer locked up so it does not walk away as well.

We hope these tips help you from having items taken from your travel trailer or the whole unit taken itself. Keep yourself safe and protected from thieves as this could ruin your whole summer road trip. We use a hitch coupler lock and a hitch pin lock at all times when the trailer is unhitched from our rig as well as add the x-chocks locked to the tire when we are at a campground.

Happy Camping!
