Car Key Signal Repeater: Complete Guide

What is a Key Repeater Device?

A keyless repeater is a device that extends the radio frequency from your key fob. This technology allows keyless entry to cars equipped with proximity keys.

Key signal repeaters are frequently employed for legal applications such as vehicle testing and security assessments.

How Does a Keyless Repeater Work?

The repeater system works by receiving the LF signal from your key fob and broadcasting it to your car. Here’s the process:

  1. The signal repeater receives the transmission from the car key
  2. It boosts the radio frequency
  3. The boosted transmission is transmitted to the target automobile
  4. The car recognizes the key signature
  5. The car unlocks as if the remote were close
