Car Key Signal Repeater: Complete Guide

What is a Keyless Repeater?

A keyless entry repeater is a equipment that amplifies the signal from your car key fob. This system allows keyless entry to automobiles equipped with keyless entry systems.

Repeater systems are frequently employed for authorized use such as automotive diagnostics and penetration testing.

How Does a Keyless Repeater Work?

The repeater system works by receiving the LF signal from your remote key and sending it to your automobile. Here’s the working principle:

1. The repeater device detects the transmission from the remote
2. It boosts the radio frequency
3. The enhanced frequency is transmitted to the vehicle
4. The car validates the key signature
5. Access is granted as if the remote were close
