How Key Fobs Work
Have you ever wondered how those small, convenient key fobs actually work their magic to lock and unlock your car with just a press of a button? Let’s peek behind the curtain and uncover the inner workings of these handy devices.
- Wireless Communication: Key fobs use a wireless radio frequency to communicate with your car’s locking system. When you press a button on the fob, it sends a signal to your vehicle, triggering the desired action.
- Battery Power: Inside a key fob, there’s a small watch battery that provides the energy needed for the device to function. These batteries are designed to last for a long time, usually several years, before needing replacement.
- Low Energy Consumption: Despite their ability to wirelessly transmit signals, key fobs are engineered to consume very little power. This low energy consumption ensures that the battery lasts for an extended period without draining quickly.
