Keyless Repeater: Complete Guide
What is a Keyless Entry Repeater?
A car key repeater is a equipment that boosts the signal from your car key fob. This device allows keyless entry to automobiles equipped with keyless entry systems.
Repeater systems are widely utilized for legitimate purposes such as car security research and penetration testing.
How Does a Repeater Device Work?
The signal amplifier works by detecting the LF signal from your remote key and broadcasting it to your car. Here’s the process:
- The repeater device picks up the transmission from the car key
- It amplifies the signal strength
- The enhanced frequency is transmitted to the target automobile
- The automobile recognizes the transmission
- Entry is permitted as if the remote were close
