Keyless Entry Repeater: Everything You Need to Know

What is a Keyless Entry Repeater?

A keyless entry repeater is a device that extends the radio frequency from your car key fob. This device allows keyless entry to vehicles equipped with proximity keys.

Keyless repeater devices are frequently employed for authorized use such as car security research and security assessments.

How Does a Repeater Device Work?

The repeater system works by capturing the LF signal from your car key and broadcasting it to your vehicle. Here’s the working principle:

1. The keyless repeater picks up the transmission from the remote
2. It amplifies the signal strength
3. The amplified signal is transmitted to the vehicle
4. The vehicle recognizes the key signature
5. The car unlocks as if the key were close
