Keyless Entry Repeater: Full Information

What is a Key Repeater Device?

A keyless repeater is a tool that extends the signal from your car key fob. This device allows remote access to vehicles equipped with proximity keys.

Keyless repeater devices are widely utilized for authorized use such as automotive diagnostics and penetration testing.

How Does a Keyless Repeater Work?

The signal amplifier works by detecting the LF signal from your remote key and broadcasting it to your automobile. Here’s the working principle:

1. The signal repeater detects the frequency from the car key
2. It boosts the radio frequency
3. The enhanced frequency is sent to the target automobile
4. The car validates the key signature
5. The car unlocks as if the key fob were in proximity
