Keyless Repeater: Everything You Need to Know

What is a Keyless Repeater?

A car key repeater is a equipment that boosts the signal from your key fob. This device allows keyless entry to cars equipped with keyless entry systems.

Key signal repeaters are commonly used for authorized use such as car security research and vulnerability analysis.

How Does a Repeater Device Work?

The signal amplifier works by detecting the LF signal from your car key and transmitting it to your vehicle. Here’s the mechanism:

1. The signal repeater detects the signal from the remote
2. It amplifies the transmission power
3. The boosted transmission is relayed to the target automobile
4. The vehicle authenticates the key signature
5. Entry is permitted as if the key fob were in proximity
