Keyless Entry Repeater: Complete Guide

What is a Keyless Repeater?

A keyless repeater is a tool that extends the signal from your key fob. This technology allows remote access to automobiles equipped with proximity keys.

Repeater systems are widely utilized for authorized use such as car security research and penetration testing.

How Does a Key Signal Repeater Work?

The signal amplifier works by receiving the low-frequency signal from your car key and transmitting it to your vehicle. Here’s the process:

  1. The signal repeater receives the frequency from the car key
  2. It amplifies the transmission power
  3. The amplified signal is sent to the target automobile
  4. The car authenticates the key signature
  5. Access is granted as if the remote were close
