Keyless Entry Repeater: Everything You Need to Know
What is a Keyless Repeater?
A car key repeater is a equipment that extends the radio frequency from your car key fob. This device allows keyless entry to automobiles equipped with keyless entry systems.
Keyless repeater devices are widely utilized for legal applications such as vehicle testing and penetration testing.
How Does a Key Signal Repeater Work?
The signal amplifier works by receiving the LF signal from your remote key and broadcasting it to your vehicle. Here’s the mechanism:
- The signal repeater picks up the frequency from the remote
- It amplifies the signal strength
- The enhanced frequency is sent to the car
- The car validates the signal
- Entry is permitted as if the key were close
