Keyless Repeater: Complete Guide

Keyless Repeater: Complete Guide

What is a Key Repeater Device?

A car key repeater is a tool that boosts the signal from your key fob. This technology allows wireless entry to cars equipped with smart key technology.

Key signal repeaters are frequently employed for authorized use such as automotive diagnostics and vulnerability analysis.

How Does a Repeater Device Work?

The keyless repeater works by capturing the LF signal from your car key and sending it to your vehicle. Here’s the process:

  1. The repeater device detects the signal from the remote
  2. It strengthens the signal strength
  3. The amplified signal is relayed to the vehicle
  4. The car validates the transmission
  5. The car unlocks as if the key fob were in proximity
