What is Remote Keyless Entry System (RKES)?

Remote keyless entry system is a technology that enables car owners to lock and unlock their cars electronically, without the need for a physical key. It includes a small device with buttons that sends a signal to the car’s computer to lock or unlock the doors. The system is activated through a remote key fob or a smartphone app.

How Does RKES Work?

RKES works by sending a signal from the remote fob or smartphone app to the car’s on-board computer, which then activates the necessary function. The signal is encrypted, making it difficult for unauthorized parties to intercept or copy it. The system uses radio frequency (RF) communication to ensure that the signal is received by the car’s computer, within a certain range.

Types of RKES

  1. Single Function RKES – has only one function that is locking and unlocking the doors.
  2. Multi-Function RKES – allows additional features like remote start or trunk release.

Benefits of RKES

  1. Convenience – you can lock or unlock your car from a distance without the need for a physical key.
  2. Safety – you can unlock your car in a well-lit area, reducing the risk of being targeted by thieves.
  3. Alertness – with the answer back feature, you can confirm that your car is locked or unlocked.
  4. Enhanced security – the encryption of the signal makes it difficult to hack, preventing unauthorized entry into your car.

Answer Back Feature

The answer back feature is an additional security feature that comes with some RKES systems. It allows you to confirm whether your car has been locked or unlocked. When you press the button to lock or unlock your car, the system sends a signal to the car’s computer, which then signals the lights and horn to flash and beep, indicating the successful locking or unlocking of the car.

Benefits of Answer Back Feature

  1. Provides peace of mind – the confirmation of successful locking or unlocking of a car gives car owners peace of mind.
  2. Acts as a theft deterrent – the flashing lights and beeps act as a deterrent to anyone who might want to enter your car without your permission.
  3. Easy to use – the feature is easy to use and can provide a quick confirmation of the status of your car.
  4. Reduces the risk of forgetting to lock the car – the audible and visual confirmation of the lock status reduces the likelihood of forgetting to lock the car.
