How to Choose The Best Trailer Hitch Lock

Wish to make sure that your money is well-spent? Then it’s essential that you keep in mind the considerations down below while shopping for a trailer hitch lock.


Due to the purpose of hitch locks, it’s quite obvious that security would be one of the top criteria. The last thing you want to pick up is a lock that may be picked and removed in a moment. Overall, it’s strongly recommended that you take a close look at the design, shape, dimension and so on prior to committing to a purchase. In addition, you should also spend some time reading the reviews of other owners of trailers to get accurate assessments and narrow down your shortlist.  


Once thieves run into secured locks that prove too hard to pick, they would likely resort to more blunt methods. That is why beside security, you must take durability into account so as to buy a worthwhile trailer hitch lock.  If subjected to continuous assaults, all locks eventually give way but sturdy ones could at least last until someone catches the thieves in the act. All in all, to reduce the risk of theft, it’s key that owners of trailers grab rugged hitch locks.

Ease Of Use

It’s a good idea to prioritize dependable hitch locks that keep trailers secured and gives thieves a tough time. That being said, you should avoid overly complex models as they may add unneeded complications to the coupling/decoupling process. Towing operations already pack a wide range of issues that require attention so it’s best that you select an intuitive lock for your trailer. Don’t let ease of use compromises security and durability though as in the end, you still need a solid hitch lock that deters theft.  


As the hitching arrangement changes considerably between trailers, you have to give compatibility some thoughts before buying a hitch lock. In the case that you grab a lock that fails to match the towing setup of your trailer, it’s as good as a paperweight. Therefore, it’s suggested that you use the parameters of your hitch as references to get a suitable hitch lock.            


Nowadays, hitch locks for trailers come at an assortment of prices so plenty of models exist for every shopping budget. Usually, owners of trailers don’t have to spend a fortune to get decent hitch locks but you must remember the rule of thumb: “You get what you pay for”. Dirt-cheap hitch locks would never incorporate state-of-the-art technologies as well as top-of-the-line materials. So as to purchase the best trailer hitch lock for your trailer, you need to put together a sound budget.  

Best Trailer Hitch Lock Brands

Owners of trailers could get hitch locks from various manufacturers but in terms of reputability, the following names tend to stand out from the rest.  


Once it comes to hitching goods, Reese is the name that you could count on. In the case that all you need is a robust trailer hitch lock, you should think about buying from Reese

Types Of Hitch Locks For Trailers

While hitch locks come in all sizes and shapes, all models on the market could be put into two types: receiver lock and coupler lock.

  • Receiver Hitch Lock

The average receiver locks for trailers look like metal pins with locks on the ends. Some models even have locks on curve ends that could take time to pull out. Designed to slide into fastener holes where hitches meet the frames of vehicles, receiver locks excel at securing hitched trailers.

  • Coupler Hitch Lock

Usually packing ball-shaped tops, coupler locks mount to the couplers of the trailer’s tongues and prevent unwanted hitching. So once it comes to securing unhitched trailers, coupler locks tend to be ideal options.

FAQs About  Trailer Hitch Locks

I lost my lock’s key. What should I do?

Like other types of locks, trailer hitch locks would be sold alongside a spare key. If you lose the spare too, it’s widely advised that you get a locksmith to help open the lock. It’s worth noting that many manufacturers of hitch locks produce replacement keys upon request. Depending on brands, the cost of the replacement keys may be covered by the warranty.

Is it possible to use keys of a certain lock to open other locks that belong to the same line?

Well, to put it plainly, all hitch locks for trailers should have unique keys which means different locks in the same line use different keys. Because of that, you don’t have to worry about your lock being opened by people who happen to own keys to a similar lock.

How could I keep my hitch lock in top shape?

In general, typical trailer hitch locks only require basic care but for good measures, you should follow the maintenance instructions in the user’s manual. In the case that you have questions, get in touch with the manufacturer for answers. Moreover, so as to avoid seizing, it’s best that you move the hitch of your trailer lock now and then during long-term storage.
