Keyless Entry Repeater: Everything You Need to Know

Keyless Entry Repeater: Everything You Need to Know

What is a Keyless Entry Repeater?

A keyless repeater is a device that amplifies the radio frequency from your vehicle remote. This system allows remote access to automobiles equipped with keyless entry systems.

Repeater systems are frequently employed for legitimate purposes such as vehicle testing and vulnerability analysis.

How Does a Key Signal Repeater Work?

The keyless repeater works by detecting the radio signal from your key fob and sending it to your vehicle. Here’s the process:

  1. The signal repeater detects the frequency from the car key
  2. It boosts the transmission power
  3. The boosted transmission is transmitted to the target automobile
  4. The car validates the transmission
  5. The car unlocks as if the key fob were close
