Keyless Entry Repeater: Everything You Need to Know

What is a Keyless Entry Repeater?

A keyless repeater is a device that extends the radio frequency from your car key fob. This device allows remote access to vehicles equipped with smart key technology.

Repeater systems are commonly used for authorized use such as automotive diagnostics and vulnerability analysis.

How Does a Repeater Device Work?

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

  1. The signal repeater picks up the signal from the key fob
  2. It amplifies the signal strength
  3. The boosted transmission is relayed to the car
  4. The car authenticates the signal
  5. The car unlocks as if the key fob were close
