Don’t be that guy walking out of WalMart to an empty space behind your truck where your bass boat used to be. For under $25 you can buy peace of mind and for a few bucks more get a variety of locks the manufacturers say are 100% theft-proof. With the investment you’ve made in your trailer, plus whatever you’re carrying on it, it just makes sense to secure it. Given the low cost, ease of installation and adaptability of the various lock models, it borders on the foolish to leave your trailer unlocked.

Customer reviews mostly confirm that manufacturers' claims about ease of installation and use are accurate. Depending on the hitch model you'll want to make sure its sized properly for your needs. If used in salty or rough conditions it helps to use some simple preventive maintenance (regular use of WD-40, for example).

Some locks are designed to secure the receiver hitch to the vehicle, and some secure the trailer coupler to the ball, preventing its use in towing the trailer away. In addition, a security-conscious owner might also opt for a wheel boot similar to what police agencies use to prevent a vehicle from moving. There are a variety of designs and configurations to meet standard Class I-V towing hitches and vehicle styles.
