What is a Trailer Hitch Lock?
A trailer hitch lock secures your trailer making it difficult for would-be thieves to simply hitch it up and disappear with your RV. They provide an excellent visible deterrent to anyone in the vicinity who may be tempted to make off with your trailer and make themselves several thousand dollars richer.
Trailer hitches are very easy to install and relatively inexpensive, especially considering how much money they could save you. Unfortunately, not everyone has a trailer hitch lock installed. Think about how easy it is for you to hitch up and drive away with your trailer for the weekend. What is there to stop it from being just as easy for anyone else?
Trailers are expensive and often have very expensive cargo and fixtures. A trailer lock is an essential piece of kit to protect your trailer and your financial investment. Without one, anyone nearby with an appropriate tow vehicle could simply drive away with your RV.
While you may live in a great area, who is to say who you’ll pass on your travels and what stopovers you’ll make?

Master Lock Swivel Head Receiver Lock
Renowned security experts Master Lock founded back in 1921, is a top brand with an excellent reputation. The Swivel Head Receiver Lock is a good budget buy, providing you with the security you need to protect your trailer when it is hitched to your tow vehicle.
Complete with two pins, two keys, and one locking swivel head, one pin is suitable for ½ inch and the other for ⅝ inch receivers, both with a usable length of 2 ¾ inches. The ½ inch locking pin is rated up to 3,500 pounds, suitable for classes I and II, while the ⅝ inch version is rated up to 10,000 pounds for class III and IV hitches.
Made from hardened steel for extra shear resistance, the unit’s chrome plating improves corrosion resistance. Easy to use, thanks to Master Lock’s Push to Lock mechanism, the locking swivel head also benefits from a Weather Tough seal to prevent dirt and moisture from entering the keyway.
Bear in mind that receiver locks are designed to be used when towing, if left on your trailer for several months without use, this model can seize up. It is very easy to lock and unlock at any angle, thanks to its 360-degree rotating swivel head, while the four-pin cylinder prevents lock picking.
While this isn’t the most robust, nor the most durable of receiver hitch locks, if you are looking for extra security and peace of mind when you stop off en route to your RVing destination, it’s a great budget choice. It also comes complete with a limited lifetime warranty.
Master Lock Universal Coupler Trailer Lock
This Universal Coupler Trailer Lock by Master Lock is a popular choice for securing unattended trailers thanks to its ease of use, high visibility, and fair price. An excellent guardian against spontaneous tow-away theft, this model fits most 1 ⅞ inch, 2-inch, and 2 5/16 inch couplers thanks to its versatile slide lock.
Made from tough hardened cast steel, this coupler lock for RVs is both rust and corrosion-resistant, complete with a bright red, highly visible finish. Potential thieves will spot your trailer lock a mile off, discouraging attempts to steal before they get up close.
The advanced locking mechanism resists prying and picking, however, it is less suitable if you live in an area with a very cold climate as it can freeze up in extreme cold. Aside from this, it is very easy to install and remove, making it an excellent model for regular RVers.
As far as affordable trailer coupler locks go, this is a great choice. It also comes with a limited lifetime warranty, testament to its superior build quality and the manufacturer’s high reputation. This model comes complete with two keys and is also available in a set with the above receiver lock and a latch lock.
Fastway Fortress Maximum Security Universal Coupler Lock
Tested on thousands of different couplers, the Fastway Fortress Maximum Security Universal Coupler Lock has been designed to fit all trailer hitches between 1 ⅞ inches and 2 5/16 inches. If you are looking for a highly secure lock to protect your unattended trailer, this is one of the very best coupler locks for your RV on the market.
Aside from its universal fit, this trailer lock also boasts a thick, highly protective housing. Its super-hardened steel shackle is chrome-plated for extra corrosion-resistance. The shackle prevents the lock from being pried off, while the detent ball is solid, not hollow, for even further protection.
Complete with an anti-drill pin and a bolt-blocked locking system, this model is one of the most secure trailer locks around. The patent-pending horizontal bend in the shackle provides a secure and snug, forward-facing fit, while the bolt on each side of the housing securely locks the shackle into place by grooving against the shackle teeth.
While this unit is not as highly visible as some of the colored alternatives, it is, nonetheless, an excellent deterrent and its shiny chrome finish makes it stand out as one serious, heavy-duty piece of kit. For extra durability and improved weather resistance, this model features a hinged cover over the lock to keep out dirt, dust, debris, and water, ensuring that your lock remains in prime condition.
Easy to install and remove, this high-security trailer coupler lock is one of the very best models around. Its universal fit makes it suitable for almost all travel trailers. While it does cost more than most of its competitors, it does have a limited lifetime warranty and is well worth the extra dollars considering the extra peace of mind it brings.
Reese Towpower Heavy Duty Coupler Lock
The Towpower Heavy Duty Coupler Lock by towing industry experts Reese is a much more solid and secure model than your average trailer coupler lock. Being a universal fit, it is suitable for securing 1 ⅞ inch, two-inch, and 2 5/16 inch trailers when not being towed.
The U-bar is made from hardened steel, while the main body is manufactured from strong, corrosion-resistant cast aluminum. Bright silver in color, it is visible, although not quite as noticeable from a distance as brightly colored versions.
It has a ratchet design with 11 locking positions for a snug fit on almost any trailer model. Note that the U-bolt only locks on one side, although as a deterrent to any opportunists, this heavy-duty coupler lock will be more than enough.
Thanks to its innovative square key design, this model makes for difficult picking. However, due to the way the lock is placed inside the casing, it can occasionally become stuck, or stick when opening on the first attempt.
On the whole, this model is a decent product for the money. While there are plenty cheaper around, the Reese Towpower Heavy Duty Coupler Lock has a better build quality and is more effective than most cheaper units. It also comes complete with a limited one-year warranty.
Trimax T-3 Premium Receiver Lock
Trimax, one of the industry leaders in receiver locking pins, have made numerous improvements over the last 10 years to their original designs. The T-3 Premium Receiver Lock is the fruit of their ongoing innovation and a highly popular choice for securing travel trailers while hitched.
With its ⅝ of an inch diameter and 2 ¾ inch span, this model fits two-inch class III and IV receivers, making it suitable for a wide variety of RVs. Made from high-quality forged stainless steel, this T3 version features a black epoxy powder coat for improved durability and weather resistance.
A protective rubber cap helps to keep dirt and water out of the lock, while the o-ring seal further protects the locking mechanism. While this is a premium model, bear in mind that as it is only intended for use when your trailer is being towed, when you’re not using it, removing it and storing it inside your trailer will extend its lifespan.
Easy to use, a one-quarter turn locks and unlocks the head. For extra security, the lock cannot be falsely locked, nor pop open. There are no internal springs to seize or break for improved durability, plus the knurling on the lock head is machined from solid forged steel.
Trimax are committed to high-quality standards and provide a lifetime warranty on all of their products. If you are looking for a receiver lock to secure your trailer when your tow vehicle is attached, this model makes a good choice for the money.
AMPLOCK RV/Trailer Coupler Lock
If you have an expensive trailer with expensive cargo, why take the risk with the limited protection afforded by some of the cheaper coupler locks? Amplock, a family-owned Canadian company, produces this high-quality lock in Canada from USA materials. It is recommended by Canadian insurers and is definitely one you’ll want to check out if you stand to lose a lot of cash from trailer theft.
Designed for 2 5/16 inch trailer couplers only, this model is designed to give a snug, extra secure fit, rather than trying to achieve a universal fit. Made from stainless steel and ducted cast iron, this heavy-duty trailer lock means business and just cannot be compared to cheaper models.
Weighing twelve pounds, this unit will slow down any cutting type attempt, while impacts cause the unit to fold or bump after impact, as it has been specifically designed to absorb shocks, rather than breaking. It provides good corrosion resistance, as well as liquid nitrogen and torch cutting resistance.
Thanks to its patented mechanism with a two-part lock, it is highly secure. This model is very easy to install, featuring a push-to-lock cylinder, while the lock’s location makes it difficult for thieves to access, complete with a rotative face to prevent drilling.
With millions of key combinations and a unique code for each customer, you have the possibility to have additional keys or locks keyed alike. While this unit does cost a fair amount, if you stand to lose thousands, spending a few hundred protecting your trailer certainly makes sense.
If you can afford it, the Amplock RV Coupler Lock is well worth the extra money for its superior quality, excellent highly-secure design, and the peace of mind that it brings.
Rhino USA Trailer Hitch Lock
Powersports accessory providers Rhino USA sell this Trailer Hitch Lock for use when towing your travel trailer. Its ⅝ inch pin is suitable for most two-inch class II and IV hitches, although the exact usable pin length is not made clear.
Made from solid forged steel, this durable trailer hitch lock is great value for money if you are looking for a bargain model and don’t mind purchasing from a non-specialist supplier. It also has the advantage of coming with a lifetime warranty to ensure that you remain fully satisfied with your purchase.
The main advantage of this model over other similar versions is that it comes with a weatherproof slide cap to protect the lock from dirt and debris. This helps to keep your lock in good working order for much longer. Also, the two included keys come with a handy rubber housing, making it easier to use them when the weather is bad.
While a great many towing products are inevitably made in China, a lot of them of excellent quality, with this supplier’s huge emphasis on its USA heritage and base, it can be a little misleading for the average consumer. That said, it is a popular product at a great price, that is also backed by an excellent warranty. So, if you are looking for a low-priced trailer hitch lock, this model could be perfect for your needs.
CURT Black Trailer Hitch Lock
The Black Trailer Hitch Lock 23518 by towing-industry specialists Curt has been designed to prevent opportunist theft of your trailer when it is hitched to your tow vehicle. It keeps your trailer secure, preventing anyone from simply detaching it at the ball mount and towing it away.
This model fits two-inch receiver tubes with its ⅝-inch diameter pin. Note that the usable pin length of this product is 2.85 inches, making it unsuitable for double-walled receiver tubes. As a barbell design trailer hatch lock, it consists of a pin with two end caps and a round locking mechanism.
Made from high-strength steel, protected by a durable black finish, this unit also benefits from a watertight dust cap. This ensures your lock remains free from dirt and debris, as well as protected from moisture and any subsequent internal
corrosion for a longer lifespan and extra dependability.
Easy to operate and install, simply turn 90-degrees to activate the lock. Two keys are included for your convenience, plus a limited lifetime warranty for manufacturing defects, with one year on parts and one year on the finish.
If you are looking for a good budget trailer hitch lock, this version by Curt is easy to use and definitely well worth its price. It will give you peace of mind when stopping off en route with your trailer to stock up on provisions or for dining.
Trimax Premium Universal Trailer Lock
For securing unattended trailers, the Trimax Premium Universal Trailer Lock fits most couplers sized 1 ⅞ inches, two inches, and 2 5/16 inches. This highly versatile model utilizes a dual ratchet system to be able to accommodate most coupler sizes. However, as the ball is a little on the small side, you may struggle to get a tight enough fit even on the smallest locking adjustment with some sizes.
Made from a solid hardened steel frame, the lower part is encased in weather-resistant ballistic grade nylon housing, complete with a sliding keyhole cover. The plastic housing is good at absorbing heavy blows, although combined with a less than snug fit, it can make it a little easier to pry off than other versions.
Featuring spring-loaded, seven-pin high-security keys, this model is designed to resist attempted drill outs. While it is easy to use, bear in mind that you need to turn the key to slide the lock into place, unlike some other versions that you can simply open and then secure without the key
Beefer and more secure than cheaper models, if you are looking for extra protection, but don’t want to spend big money, then this could be the best trailer lock for your RV.

Setting your budget for a trailer hitch lock can be a little tricky.
There are plenty of low-priced models that offer good levels of protection – most particularly from would-be, opportunist thieves. These units tend to cost between $15-$30. If you don’t already have one and are on a budget, it’s a small price to pay to put off anyone around from simply hitching up to and making off with your trailer.
You’ll also find models in the $30-$80 price range that come with a more solid construction and occasionally improved anti-theft design. Some versions at the higher end of this price bracket are really worth the extra in terms of strength and superior design. However, there are plenty around the $50-$60 mark that don’t provide much more protection than cheaper versions.
If you are storing your trailer in an at-risk area, or outdoors unattended over long periods, spending several hundred dollars on a premium trailer lock could save you thousands. This is especially true if you have expensive cargo, that you may not be able to recoup the full cost of via your RV insurance.
Our advice, if you have the money and an expensive trailer, best to play it safe with an expensive lock. If you don’t, some of the better budget models are just as effective as those in the mid-price range.
Combining your hitch lock, cheap or expensive, with an additional latch style coupler lock plus a trailer wheel chock lock will maximize your theft-deterrence levels.
Hitch Class/Coupler Size
Before you start looking at trailer hitch locks, you’ll need to determine what size you’ll need. It is essential that your lock matches up with what you’re towing.
Receiver trailer hitch locks usually come with pins in either ½ inch or ⅝ inch diameters. Class II hitches take ½ inch pins and have a 1 ¼ inch receiver size, whereas the ⅝ inch ones are compatible with class III, IV, and V. Class III and class IV have two-inch receivers, whereas class V trailers can have two-inch, 2 5/16 inches or 2 ½ inch receivers.
If you are looking for a coupler hitch lock, you’ll need to make sure that the diameter of your hitch ball is compatible with the ball on your lock. In any case, if you are unsure of a hitch lock’s compatibility with your trailer, reach out to the manufacturer and see if they can advise you.
Material
Hardened steel is one of the best choices for trailer locks, given its high tensile strength. Some units include aluminum or plastic components, however, steel is generally the most secure choice.
Durability & Corrosion-resistant
Make sure that your steel trailer lock has a weather-resistant finish to protect it from rusting. Powder-coated finishes also work well against the harsh conditions it will face on the road, in the case of hitch locks.
To ensure that your trailer hitch or coupler lock has a long lifespan, it is essential that the internal workings are protected as well as the exterior. Choosing a model with a sliding rubber protection cap over the keyway is a great way to keep the lock free from moisture and rust.
Ease of use
For regular RVers, ease of use is a priority when it comes down to choosing trailer locks.
You’ll want to unlock your coupler lock on a regular basis, as well as locking and unlocking your receiver lock. The details can make all of the difference, so opt for a model with a push-to-lock mechanism, get your unit ready to go, and simply lock it shut with a touch rather than a key.
Some models by specialist towing and security manufacturers offer you the possibility to key certain items alike, or to purchase packs consisting of a hitch lock, a coupler latch lock, and a trailer tongue lock all keyed alike. This can make getting your trailer ready for your next trip much easier with just one set of keys.
Visibility
The more visible your lock is, due to its size or brightly colored finish, the more of a deterrent it provides. While it is extremely difficult to prevent a committed thief with plenty of resources and time to plan from stealing, the more common opportunistic thief can easily be deterred with simple measures, such as a highly visible trailer lock.
Unique Keys
Purchasing a hitch lock with unique keys is a good way to ensure extra security. Having unique keys means that no other hitch lock keys could be used to open your lock, only your set will work. If this isn’t possible on your list of potential purchases, opt for a hitch lock with a very high number of key combinations.
Types of Trailer Hitch Lock
There are two main types of trailer hitch lock. You’ll need one of each, one for when you’re towing your trailer and the other for when it’s unhitched.
Receiver Style Hitch Locks
Receiver hitch locks are used when your trailer is attached to your tow vehicle. They take the place of your hitch pin and lock closed. Once locked, no one can unhitch your trailer without the key – ideal for worry-free stops on route to your destination stocking up on provisions or for taking a leisurely meal.
These locks are also invaluable for ensuring that your RV hitch-mounted accessories remain secure, especially rear-mounted hitch cargo carriers and bike racks. To protect your trailer from theft, bear in mind that a receiver style hitch lock will only be effective when it is attached to your tow vehicle. Otherwise, you will need a coupler hitch lock.
There are three main types of receiver hitch locks:
- Right angle hitch locks – these models feature a front-accessible lock, with key access on the receiver tube side of your hitch. This makes for easier access, especially useful if you need to regularly lock and unlock your receiver hitch.
- Barbell hitch lock – the classic design of most trailer hitch locks. This version features a standard hitch pin-like bar complete with two end caps and key access to the side.
- Deadbolt hitch lock – this version looks very much like your standard hitch pin, except the end is replaced with a heavy-duty lock. Easy to fit and use, it also makes a good visual deterrent.
Coupler Hitch Locks
Coupler hitch locks are used to protect your trailer when it is unhitched from your tow vehicle. They prevent anyone with a hitch ball from simply attaching your trailer and driving it away.
To do so, coupler hitch locks generally feature a U-shaped design that fits over the top of the coupler on your trailer’s tongue. This section locks into a ball-shaped attachment that fits where your vehicle’s hitch ball enters the coupler. With a coupler hitch lock installed, it is impossible for a vehicle to hitch up to your trailer.
