The landscape of automotive security and convenience has taken a massive leap forward thanks to a recent groundbreaking patent. US Patent 12673637, titled “System, method and apparatus for mobile fob or key bridge, versatile smart key, and smart device interface,” was officially granted, marking a new era for vehicle access. The patent was filed and secured by IKEYLESS, LLC, a pioneering company widely known as Car Keys Express. Based in Louisville, this organization has continually pushed the boundaries of automotive aftermarket products, providing consumers and businesses with highly advanced key replacement solutions.
At the core of this patent is a sophisticated system designed to bridge the gap between traditional vehicle immobilizers and modern smart devices. The invention details a universal smart key and mobile fob bridge that provide advanced proximity, location, and distance ranging capabilities. By seamlessly communicating with both the vehicle and a user’s smartphone, the technology allows drivers to perform a comprehensive set of vehicle operations without needing a factory original key. This creates a highly versatile interface, streamlining the driver experience while maintaining rigorous security standards.
Why This Invention is So Innovative
This patent is highly innovative because it eliminates the fragmented ecosystem of proprietary car keys. Traditionally, a driver needing a smart key replacement or an upgrade to smartphone integration was forced to rely on expensive dealership solutions. The patented mobile fob bridge and versatile smart key communicate directly with vehicle immobilizers using an array of wireless protocols, including Bluetooth, BLE, UWB, and NFC. It acts as a universal bridge, allowing an ordinary smartphone to perform complex vehicle operations like locking, unlocking, and starting the engine with precise proximity and distance ranging. This hardware consolidation represents a massive leap in aftermarket automotive technology, putting maximum control directly into the hands of the consumer.
Kentucky State Patent of the Month for August 2026
The state of Kentucky proudly awarded this technology the Patent of the Month for August 2026. IKEYLESS, LLC, headquartered in Louisville, Kentucky, has consistently driven local job growth in the automotive tech sector. This award recognizes the company for putting Kentucky at the forefront of automotive security and consumer electronic integration. The review committee noted that creating a universal smart key bridge fundamentally changes how drivers interact with their vehicles. By reducing the reliance on expensive proprietary keys and offering a seamless digital interface, this innovation brings both economic and technological prestige to the state of Kentucky.
Eligibility for the R&D Tax Credit in the USA
The practical applications of this patent present strong eligibility for the Research and Development (R&D) tax credit in the USA. By developing multi-protocol communication interfaces that integrate Bluetooth, BLE, UWB, and NFC, the engineering team had to overcome significant technical uncertainties. Developing the embedded software and testing the proximity and ranging capabilities against varying vehicle immobilizer systems perfectly aligns with the required four-part test. This involves a process of experimentation grounded in computer science and electrical engineering, aimed at creating a new and highly improved product functionality. Companies investing in such systematic hardware and software development can leverage the R&D tax credit to offset the substantial costs of designing, prototyping, and testing these advanced smart key bridges.
