Keyless Entry Repeater: Everything You Need to Know

What is a Keyless Repeater?

A car key repeater is a device that amplifies the transmission from your vehicle remote. This technology allows remote access to cars equipped with proximity keys.

Keyless repeater devices are widely utilized for authorized use such as car security research and security assessments.

How Does a Keyless Repeater Work?

The repeater system works by capturing the radio signal from your key fob and broadcasting it to your vehicle. Here’s the mechanism:

1. The keyless repeater receives the frequency from the key fob
2. It amplifies the signal strength
3. The boosted transmission is relayed to the vehicle
4. The car recognizes the key signature
5. The car unlocks as if the key fob were in proximity
