Keyless Repeater: Complete Guide
What is a Key Repeater Device?
A keyless entry repeater is a device that extends the radio frequency from your car key fob. This device allows keyless entry to automobiles equipped with keyless entry systems.
Key signal repeaters are commonly used for legal applications such as vehicle testing and vulnerability analysis.
How Does a Repeater Device Work?
The keyless repeater works by capturing the LF signal from your remote key and transmitting it to your car. Here’s the working principle:
- The signal repeater picks up the frequency from the car key
- It strengthens the radio frequency
- The amplified signal is relayed to the car
- The automobile validates the signal
- Entry is permitted as if the key fob were close
