Understanding Your Lexus LS400 Key Fob
Before we dive into programming, it’s helpful to understand the technology at play. Your 1998 Lexus LS400 likely utilizes a standard RF (radio frequency) key fob. This means the fob sends a specific radio signal to your car’s receiver to lock, unlock, and sometimes even start the engine.
