Car Key Signal Repeater: Everything You Need to Know

What is a Key Repeater Device?

A keyless entry repeater is a equipment that boosts the signal from your vehicle remote. This technology allows remote access to vehicles equipped with keyless entry systems.

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

How Does a Key Signal Repeater Work?

The repeater system works by receiving the low-frequency signal from your key fob and sending it to your car. Here’s the working principle:

1. The signal repeater picks up the frequency from the key fob
2. It amplifies the radio frequency
3. The boosted transmission is sent to the vehicle
4. The vehicle validates the transmission
5. Access is granted as if the key fob were in proximity
