Keyless Entry Repeater: Complete Guide

Keyless Entry Repeater: Complete Guide

What is a Keyless Repeater?

A keyless entry repeater is a equipment that amplifies the transmission from your vehicle remote. This technology allows remote access to cars equipped with keyless entry systems.

Key signal repeaters are widely utilized for legal applications such as car security research and vulnerability analysis.

How Does a Repeater Device Work?

The repeater system works by capturing the low-frequency signal from your key fob and transmitting it to your car. Here’s the process:

  1. The keyless repeater picks up the transmission from the car key
  2. It boosts the signal strength
  3. The enhanced frequency is transmitted to the target automobile
  4. The automobile authenticates the key signature
  5. The car unlocks as if the key were close
