Car Key Signal Repeater: Everything You Need to Know
What is a Key Repeater Device?
A car key repeater is a equipment that amplifies the radio frequency from your vehicle remote. This device allows keyless entry to cars equipped with proximity keys.
Key signal repeaters are frequently employed for legitimate purposes such as car security research and penetration testing.
How Does a Key Signal Repeater Work?
The signal amplifier works by detecting the LF signal from your key fob and sending it to your automobile. Here’s the mechanism:
- The signal repeater receives the signal from the remote
- It boosts the transmission power
- The amplified signal is sent to the car
- The automobile recognizes the key signature
- The car unlocks as if the key were close
