Keyless Repeater: Complete Guide
What is a Keyless Entry Repeater?
A keyless entry repeater is a tool that extends the radio frequency from your key fob. This device allows remote access to automobiles equipped with smart key technology.
Keyless repeater devices are widely utilized for authorized use such as vehicle testing and vulnerability analysis.
How Does a Repeater Device Work?
The repeater system works by detecting the radio signal from your car key and broadcasting it to your car. Here’s the mechanism:
- The signal repeater detects the signal from the car key
- It boosts the signal strength
- The amplified signal is transmitted to the target automobile
- The automobile validates the signal
- Entry is permitted as if the remote were close
