Keyless Entry Repeater: Everything You Need to Know

What is a Keyless Repeater?

A keyless repeater is a tool that boosts the transmission from your key fob. This technology allows wireless entry to vehicles equipped with keyless entry systems.

Key signal repeaters are commonly used for legal applications such as vehicle testing and vulnerability analysis.

How Does a Keyless Repeater Work?

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

  1. The signal repeater receives the transmission from the car key
  2. It amplifies the transmission power
  3. The enhanced frequency is transmitted to the target automobile
  4. The car authenticates the signal
  5. Entry is permitted as if the key were nearby
