Car Key Signal Repeater: Full Information

What is a Key Repeater Device?

A keyless entry repeater is a tool that amplifies the transmission from your vehicle remote. This technology allows keyless entry to automobiles equipped with smart key technology.

Repeater systems are frequently employed for legal applications such as car security research and penetration testing.

How Does a Keyless Repeater Work?

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

1. The keyless repeater detects the signal from the remote
2. It strengthens the signal strength
3. The enhanced frequency is sent to the vehicle
4. The automobile authenticates the transmission
5. Entry is permitted as if the key were in proximity
