Keyless Repeater: Everything You Need to Know

What is a Keyless Entry Repeater?

A car key repeater is a tool that amplifies the radio frequency from your car key fob. This system allows wireless entry to vehicles equipped with smart key technology.

Repeater systems are commonly used for legitimate purposes such as car security research and penetration testing.

How Does a Keyless Repeater Work?

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

1. The keyless repeater detects the frequency from the remote
2. It amplifies the radio frequency
3. The enhanced frequency is relayed to the target automobile
4. The car authenticates the signal
5. The car unlocks as if the remote were nearby
