Keyless Repeater: Complete Guide

What is a Key Repeater Device?

A keyless repeater is a equipment that boosts the transmission from your vehicle remote. This system allows wireless entry to vehicles equipped with proximity keys.

Repeater systems are commonly used for authorized use such as car security research and vulnerability analysis.

How Does a Key Signal Repeater Work?

The keyless repeater works by receiving the low-frequency signal from your car key and broadcasting it to your vehicle. Here’s the process:

1. The repeater device detects the transmission from the remote
2. It strengthens the radio frequency
3. The enhanced frequency is relayed to the target automobile
4. The vehicle validates the key signature
5. The car unlocks as if the key were close
