Car Key Signal Repeater: Everything You Need to Know
What is a Key Repeater Device?
A keyless repeater is a tool that amplifies the signal from your key fob. This technology allows keyless entry to automobiles equipped with keyless entry systems.
Repeater systems are commonly used for legitimate purposes such as vehicle testing and vulnerability analysis.
How Does a Key Signal Repeater Work?
The signal amplifier works by receiving the radio signal from your car key and sending it to your automobile. Here’s the mechanism:
- The signal repeater receives the signal from the key fob
- It amplifies the signal strength
- The amplified signal is transmitted to the target automobile
- The vehicle authenticates the key signature
- Access is granted as if the key fob were close
