Keyless Entry Repeater: Complete Guide

What is a Keyless Entry Repeater?

A keyless repeater is a device that extends the transmission from your vehicle remote. This technology allows wireless entry to vehicles equipped with smart key technology.

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

How Does a Key Signal Repeater Work?

The repeater system works by receiving the LF signal from your car key and broadcasting it to your automobile. Here’s the working principle:

1. The keyless repeater picks up the frequency from the key fob
2. It boosts the radio frequency
3. The enhanced frequency is sent to the vehicle
4. The automobile validates the transmission
5. The car unlocks as if the key fob were in proximity
