Car Key Signal Repeater: Everything You Need to Know

What is a Key Repeater Device?

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

Key signal repeaters are commonly used for legitimate purposes such as vehicle testing and penetration testing.

How Does a Keyless Repeater Work?

The keyless repeater works by receiving the low-frequency signal from your key fob and broadcasting it to your vehicle. Here's the mechanism:

1. The repeater device receives the transmission from the car key
2. It boosts the signal strength
3. The boosted transmission is transmitted to the car
4. The automobile recognizes the signal
5. Entry is permitted as if the key were close
