Keyless Entry Repeater: Everything You Need to Know

What is a Key Repeater Device?

A keyless repeater is a tool that extends the radio frequency from your vehicle remote. This device allows keyless entry to automobiles equipped with proximity keys.

Key signal repeaters are widely utilized for authorized use such as car security research and security assessments.

How Does a Keyless Repeater Work?

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

1. The keyless repeater picks up the signal from the key fob
2. It amplifies the transmission power
3. The enhanced frequency is relayed to the vehicle
4. The car validates the transmission
5. Access is granted as if the key were in proximity
