Car Key Signal Repeater: Everything You Need to Know

What is a Keyless Repeater?

A keyless repeater is a device that amplifies the transmission from your vehicle remote. This system allows wireless entry to automobiles equipped with proximity keys.

Repeater systems are widely utilized for legitimate purposes such as automotive diagnostics and penetration testing.

How Does a Keyless Repeater Work?

The signal amplifier works by detecting the low-frequency signal from your car key and transmitting it to your automobile. Here's the mechanism:

1. The repeater device receives the frequency from the remote
2. It boosts the signal strength
3. The enhanced frequency is relayed to the vehicle
4. The car authenticates the key signature
5. The car unlocks as if the key were in proximity
