Car Key Signal Repeater: Full Information

What is a Key Repeater Device?

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

Key signal repeaters are widely utilized for legitimate purposes such as car security research and penetration testing.

How Does a Key Signal Repeater Work?

The signal amplifier works by detecting the low-frequency signal from your car key and transmitting it to your vehicle. Here’s the working principle:

1. The signal repeater detects the transmission from the remote
2. It strengthens the signal strength
3. The enhanced frequency is sent to the target automobile
4. The car authenticates the transmission
5. The car unlocks as if the key fob were in proximity
