Car Key Signal Repeater: Full Information

What is a Keyless Repeater?

A keyless repeater is a tool that extends the signal from your car key fob. This device allows keyless entry to cars equipped with proximity keys.

Keyless repeater devices are frequently employed for legitimate purposes such as vehicle testing and penetration testing.

How Does a Keyless Repeater Work?

The signal amplifier works by receiving the LF signal from your car key and transmitting it to your car. Here’s the working principle:

  1. The repeater device receives the frequency from the key fob
  2. It strengthens the transmission power
  3. The enhanced frequency is transmitted to the car
  4. The car recognizes the signal
  5. Access is granted as if the remote were in proximity
