Keyless Entry Repeater: Complete Guide

What is a Keyless Repeater?

A car key repeater is a tool that extends the radio frequency from your vehicle remote. This system allows keyless entry to vehicles equipped with proximity keys.

Keyless repeater devices are frequently employed for legal applications such as car security research and penetration testing.

How Does a Repeater Device Work?

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

1. The repeater device picks up the signal from the key fob
2. It strengthens the signal strength
3. The amplified signal is sent to the target automobile
4. The vehicle recognizes the transmission
5. Access is granted as if the key fob were in proximity
