Keyless Repeater: Everything You Need to Know

What is a Keyless Entry Repeater?

A car key repeater is a equipment that amplifies the radio frequency from your key fob. This device allows wireless entry to cars equipped with proximity keys.

Keyless repeater devices are widely utilized for authorized use such as car security research and penetration testing.

How Does a Key Signal Repeater Work?

The keyless repeater works by capturing the radio signal from your car key and transmitting it to your vehicle. Here’s the mechanism:

1. The signal repeater receives the frequency from the car key
2. It strengthens the transmission power
3. The enhanced frequency is transmitted to the target automobile
4. The automobile recognizes the transmission
5. Access is granted as if the key were nearby
