Car Key Signal Repeater: Complete Guide

Car Key Signal Repeater: Complete Guide

What is a Key Repeater Device?

A keyless entry repeater is a device that boosts the signal from your car key fob. This system allows remote access to vehicles equipped with proximity keys.

Key signal repeaters are frequently employed for legal applications such as car security research and security assessments.

How Does a Keyless Repeater Work?

The signal amplifier works by capturing the radio signal from your remote key and broadcasting it to your automobile. Here's the process:

  1. The keyless repeater picks up the transmission from the remote
  2. It amplifies the signal strength
  3. The enhanced frequency is sent to the target automobile
  4. The automobile authenticates the transmission
  5. The car unlocks as if the key fob were in proximity
