About Us

Road Guardian LLC was formed in Memphis, TN by Jacob Arnold and Samuel Jeong in 2025 however our idea was created in 2022. While living in Memphis we noticed a massive surge in auto thefts, not only in our area, but other cities as well. In typical engineering fashion we knew we could solve this problem. Our goal was not to make another run of the mill anti-auto theft device, but make one that was seamless to the driver and causes no extra steps in starting your vehicle. Thus the Engine Lock was born.

Our Goal

To create a product that is easy to the customer and hard on the thief!
