Keyless Repeater: Complete Guide

What is a Key Repeater Device?

A car key repeater is a equipment that extends the radio frequency from your vehicle remote. This device allows wireless entry to vehicles equipped with keyless entry systems.

Repeater systems are widely utilized for authorized use such as car security research and vulnerability analysis.

How Does a Repeater Device Work?

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

1. The repeater device receives the frequency from the key fob
2. It amplifies the transmission power
3. The amplified signal is sent to the car
4. The automobile recognizes the key signature
5. Entry is permitted as if the key were in proximity
