Car Key Signal Repeater: Everything You Need to Know

What is a Keyless Repeater?

A keyless repeater is a equipment that amplifies the signal from your vehicle remote. This system allows wireless entry to vehicles equipped with keyless entry systems.

Repeater systems are widely utilized for legitimate purposes such as car security research and vulnerability analysis.

How Does a Repeater Device Work?

The repeater system works by detecting the radio signal from your remote key and transmitting it to your car. Here’s the process:

1. The repeater device picks up the frequency from the key fob
2. It amplifies the transmission power
3. The amplified signal is sent to the vehicle
4. The car recognizes the signal
5. Entry is permitted as if the key were nearby
