Keyless Repeater: Complete Guide

What is a Keyless Entry Repeater?

A car key repeater is a equipment that amplifies the signal from your vehicle remote. This device allows remote access to cars equipped with keyless entry systems.

Keyless repeater devices are commonly used for legal applications such as vehicle testing and security assessments.

How Does a Key Signal Repeater Work?

The keyless repeater works by capturing the low-frequency signal from your key fob and sending it to your automobile. Here’s the process:

1. The repeater device detects the frequency from the car key
2. It amplifies the radio frequency
3. The boosted transmission is transmitted to the target automobile
4. The automobile authenticates the signal
5. Access is granted as if the key were close
