Understanding Car Key Fobs

What is a Car Key Fob?

A car key fob is a small electronic device used to control various functions of your vehicle, such as locking and unlocking doors, starting the engine, and even opening the trunk. These fobs use radio frequency identification (RFID) technology to communicate with your car.

Types of Car Key Fobs

There are several types of car key fobs, each with different functionalities:

  • Standard Remote Key Fob: Allows you to lock/unlock doors and may have additional features like panic alarms.
  • Transponder Key: Contains a chip that communicates with your car’s ignition system, providing an extra layer of security.
  • Smart Key: Also known as a keyless entry remote, this type allows you to start your car without physically inserting the key, typically by pressing a button.
  • Switchblade Key: Combines a traditional key and a remote control in one unit.

How Car Key Fobs Work

Car key fobs send a signal to the car’s receiver, usually within a range of 5-20 meters. When you press a button on the fob, it sends a coded signal to the car. If the car recognizes the code, it performs the requested action, like unlocking the doors.
