Buyer’s Guide to Finding a Trailer Hitch Lock

Camping trips can quickly go from being fun and exciting to gloomy when you lose a trailer and your important supplies with it. Getting your trailer secured is the only way to stay safe on your next outing, and the best way to do that is by purchasing a trailer hitch lock. Even though the primary purpose of hitch locks is to protect your trailer and camping gear, there’s a lot of consideration that goes into finding a lock that fulfills its purpose. Apart from seeking the right features, you should also focus on your requirements. This buyer’s guide details everything you need to know about trailer hitch locks to help you make the best purchase decision.

Features to Look for in a Trailer Hitch Lock

Whether you go out shopping in the auto store or browse hitch locks online, here are some features you should ultimately focus on:

Locking mechanism

Since security is the biggest reason for buying a trailer hitch lock, the locking system is the first thing you need to consider. To make sure the trailer is kept out of harm’s way, the coupler lock must be impenetrable by means including prying and picking. While a key locking system is standard in every hitch lock, having either a code combination or barbell lock on top can help if you are intending to explore isolated areas. If you are set to visit a popular camping spot, however, having a push-on lock with key access may suffice.

Design compatibility

Purchasing a high-end hitch lock with a state-of-the-art locking mechanism will be no use if the design is incompatible with your trailer tongue and coupler. Most hitch locks are mainly categorized as either universal or deadbolt. Universal locks, as the name suggests, are adaptable and versatile with sizes ranging between 1-⅞ inches and 2-5/16 inches. This makes them compatible with trailers and pickup trucks with a range of coupler shapes and styles. These locks function through the use of a sturdy metal ball that fits into the coupler hole while the bridge on top secures the junction. Deadbolt locks, on the other hand, contain sturdy metal hitch pins that are inserted in the coupler holes. Compared to universal hitch locks, deadbolts provide a more secure fitting for RVs. Since most RV hitches have varying dimensions, make sure to purchase a hitch lock that fits your own.

Material

Although the quality of locks plays an effective role in safeguarding your trailer, they will be of no use if the lock is made from flimsy materials. Not every thief is delicate enough to pick locks, some prefer the hard way of breaking the lock altogether. The lock you choose should be built of sturdy aluminum, cast iron, or stainless steel that can take a beating. While you’re at it, look for a product that’s treated with an anti-corrosive material to make the trailer hitch lock more durable.

Factors to Consider for the Right Trailer Lock

While you are shortlisting products based on features, selecting the perfect hitch lock means considering what you will be using the hitch lock for. What are your towing needs? What is the coupler size of your vehicle? And how often do you hitch trailers? Let’s figure it all out in this section.

Identifying the correct size

The first step towards making the right purchase is knowing the size of the vehicle coupler and trailer tongue. The hitch lock size should match the trailer coupler size for a secure and reliable fit. Identify the opening length of the receiver tube along with the trailer ball size. Measure the diameter of the hole punched in the coupler, especially if you drive an RV. These measurements will help you buy a suitable hitch lock.

How often do you tow?

If you are a traveler who’s always on the move, locking and unlocking hitch locks time after time can be a bother, especially if you are using a lock with an advanced locking mechanism. If you are mostly staying on paved road networks, you may not need the extra safety when hitch pins can suffice. Don’t want to take any chances with your trailer? Then get something with a streamlined locking and unlocking system that doesn’t cost you time or effort in the process. If you set out on a camping trip every season, choosing a sophisticated and durable trailer hitch lock would be a great option.

When do you need a trailer hitch lock?

The purpose of your trip will help you determine whether you’ll be leaving your RV or trailer unattended. In simple terms, if you have a passion for hiking or camping, you will need to leave your RV behind for hours at stretch. Leaving your trailer and camping gear behind without supervision is something you don’t want to gamble on. It is a good idea to choose a sturdy safety lock like an over-lip trailer hitch lock to give you much-needed peace of mind on all of your adventures. Nevertheless, if you intend to take a short break somewhere or camp overnight near your RV, a simple latch-style lock will get the job done. If, on the other hand, you are searching for a lock for a trailer that will mostly stay parked in a garage or parking lot, the strength and longevity of the lock would matter most. Although garages and parking lots don’t have security concerns, extreme weather conditions may be more of an issue than unwanted robberies. Make sure to buy a heavy-duty chrome-plated coupler lock that can survive against extreme weather elements, including sunlight, UV rays, sleet, road grime, rain, and snow.

Conclusion

Before setting off on your next camping trip, give some thought to improving the safety and security of your trailer. Getting your trailer stolen in the middle of nowhere can jeopardize the entire trip. It is wiser to spend your money on a reliable and effective trailer hitch lock that safeguards your trailer than to risk your and your travel buddies’ safety. After reviewing an extensive variety of safety locks, we have shortlisted the five best trailer hitch locks for you to buy before beginning this year’s trip. The buyer’s guide can also equip you with the knowledge to ensure you are making the right decision.
