Decoding the Magic: How Car Fobs Work
Car fobs operate using radio waves to communicate with your vehicle. Each fob transmits a unique coded signal, which is recognized by the receiver in your car. When you press a button on your fob, such as the unlock button, it sends a specific radio signal to the car. If the received signal matches the programmed code, the car’s system performs the requested action.
Types of Car Fobs: From Basic to Advanced
Car fobs have evolved significantly over the years. Early models offered basic lock and unlock functions, while modern fobs offer features like remote start, panic alarms, and even trunk release. Here are a few common types:
- Basic Remote Keyless Entry (RKE): These offer basic lock, unlock, and panic alarm functionalities.
- Smart Key/Keyless Entry and Start (KES): These allow you to unlock and start your car without even taking the fob out of your pocket or bag.
- Proximity Key Fob (PKF) / Passive Keyless Entry (PKE): A highly advanced type that automatically unlocks the doors as you approach the vehicle and allows push-button start.

What’s Inside a Car Fob?
Inside the seemingly simple shell of a car fob lies a miniature circuit board with a microchip, a battery, and a radio frequency transmitter. The microchip stores the unique code that your car recognizes, the battery powers the device, and the transmitter sends the coded signals to the car.
