Keyless Repeater: Everything You Need to Know

What is a Keyless Entry Repeater?

A car key repeater is a equipment that extends the radio frequency from your vehicle remote. This system allows remote access to vehicles equipped with proximity keys.

Repeater systems are frequently employed for legitimate purposes such as vehicle testing and vulnerability analysis.

How Does a Repeater Device Work?

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

1. The signal repeater detects the transmission from the car key
2. It strengthens the radio frequency
3. The boosted transmission is relayed to the vehicle
4. The car recognizes the signal
5. Access is granted as if the key fob were close
