Keyless Repeater: Complete Guide

What is a Keyless Entry Repeater?

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

Key signal repeaters are commonly used for authorized use such as car security research and penetration testing.

How Does a Repeater Device Work?

The keyless repeater works by capturing the low-frequency signal from your remote key and transmitting it to your vehicle. Here’s the process:

1. The signal repeater receives the transmission from the car key
2. It boosts the radio frequency
3. The enhanced frequency is sent to the car
4. The vehicle authenticates the transmission
5. Entry is permitted as if the remote were nearby
