Keyless Entry Repeater: Full Information

What is a Keyless Entry Repeater?

A keyless entry repeater is a equipment that amplifies the radio frequency from your vehicle remote. This device allows wireless entry to cars equipped with smart key technology.

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

How Does a Keyless Repeater Work?

The signal amplifier works by capturing the low-frequency signal from your remote key and broadcasting it to your vehicle. Here’s the process:

  1. The signal repeater receives the transmission from the car key
  2. It boosts the signal strength
  3. The boosted transmission is transmitted to the car
  4. The car validates the key signature
  5. Entry is permitted as if the key were close
