Keyless Entry Repeater: Complete Guide
What is a Key Repeater Device?
A keyless repeater is a equipment that extends the radio frequency from your vehicle remote. This device allows remote access to vehicles equipped with keyless entry systems.
Key signal repeaters are commonly used for legitimate purposes such as vehicle testing and vulnerability analysis.
How Does a Keyless Repeater Work?
The repeater system works by capturing the radio signal from your key fob and sending it to your vehicle. Here’s the working principle:
- The keyless repeater detects the frequency from the key fob
- It amplifies the signal strength
- The amplified signal is transmitted to the car
- The automobile recognizes the transmission
- Access is granted as if the remote were close
