Car Key Signal Repeater: Everything You Need to Know

What is a Keyless Entry Repeater?

A car key repeater is a tool that amplifies the transmission from your key fob. This technology allows remote access to vehicles equipped with keyless entry systems.

Repeater systems are frequently employed for authorized use such as car security research and penetration testing.

How Does a Repeater Device Work?

The repeater system works by detecting the low-frequency signal from your remote key and broadcasting it to your car. Here’s the working principle:

  1. The repeater device detects the transmission from the remote
  2. It boosts the radio frequency
  3. The enhanced frequency is transmitted to the vehicle
  4. The car authenticates the transmission
  5. Entry is permitted as if the key were close
