Discover how our strong and economic trailer lock collection can prevent cargo theft. Our coupler locks offer superior security, affordability, and peace of mind.
I’m Bill Smith, the CEO of S5 Locks. I established my company’s foundation through my personal research for a trailer coupler lock capable of ensuring the security of my church’s trailer.
Through this research, I quickly recognized that the majority of locks available on the market could be eliminated within 20 seconds using cutting or sledgehammer methods, prompting me to devise a superior solution.

First, by referencing the trailer coupler’s distinctive design, I removed vulnerabilities that potential thieves could exploit. Furthermore, I constructed the custom-fit lock from ¼” structural steel to ensure durability. I take pride in providing a product of such strength that I still utilize it to safeguard my own belongings.
What began as a side project transformed into my life’s passion. Today, I actively design, construct, and sell custom-fit trailer coupler locks that possess both impressive strength and appearance. Often, the mere presence of these locks serves as a deterrent to thieves!

I operate from Texas, a state that ranked as the second most targeted region for cargo theft in 2022. This type of theft witnessed a 20% increase from 2021, resulting in a total estimated loss of $223 million in stolen cargo. Experiencing firsthand the extent of this issue compelled me to develop a truly exceptional product. We provide the most durable, cost-effective, and exceptionally efficient trailer locks, empowering you to safeguard your trailer from becoming another statistic.
My goal is to ensure all trailer owners feel confident that when they “lock it and leave it,” their property remains securely in their possession.
