Buying Guide: Towing Hitch Lock

5 Best Towing Hitch Locks

Before we go shopping, it’s crucial to understand what exactly you need from a towing hitch lock. Is it for securing your trailer at night or while on long drives? Whatever your needs, the best towing hitch lock will provide you with peace of mind and effective security.

When it comes to towing hitch locks, several factors contribute to a model earning the title of the ‘best’. 


Firstly, a hitch lock needs to be compatible with the type and size of your vehicle’s hitch. Locks are typically designed to fit a range of hitch sizes, from 1-7/8″ to 2-5/16″. Ensure the lock you choose fits your specific hitch size.

Material and Durability

Secondly, the best towing hitch locks are made from strong, durable materials like hardened steel or aluminum. These locks are resistant to both physical attempts at removal and to the elements, including rust and corrosion.

Lock Mechanism

Thirdly, the locking mechanism is crucial. Keyed locks offer excellent security but require you to keep track of the key. Combination locks provide flexibility, but the code should be unique and hard to guess.

Ease of Use

Finally, the best towing hitch locks should be easy to install and remove (for the owner, not the thieves!). If a lock is too complex, it might not be worth the hassle, no matter how secure it might be.

Making the Right Choice

Choosing the best towing hitch lock comes down to personal preference and needs. Assess your vehicle, consider your driving habits, and decide what features are most important to you. Whether it’s the strength of Rhino USA, the security of Master Lock, or the visibility of REESE Towpower, your perfect match is out there.

Generally, you should remove the hitch lock before towing. Its primary purpose is to secure your trailer when it’s not in use. Always consult the manufacturer’s instructions for safe practice.

Absolutely! Hitch locks are a cost-effective way to deter theft and give you peace of mind when leaving your trailer unattended. It’s a small investment for significant security.

While no security measure is 100% foolproof, a hitch lock significantly reduces the likelihood of trailer theft by making it more difficult for thieves to unhitch and drive away with your trailer.


Remember, the best towing hitch lock is one that fits your hitch, is made from durable materials, has a secure locking mechanism, and is easy to use. Whether you’re hitting the road or parking your trailer, a quality towing hitch lock can provide the security and peace of mind you need.
