Car Key Signal Repeater: Complete Guide
What is a Keyless Entry Repeater?
A keyless entry repeater is a tool that boosts the radio frequency from your car key fob. This system allows keyless entry to vehicles equipped with keyless entry systems.
Keyless repeater devices are commonly used for legitimate purposes such as car security research and vulnerability analysis.
How Does a Repeater Device Work?
The keyless repeater works by capturing the LF signal from your car key and transmitting it to your automobile. Here’s the mechanism:
- The signal repeater detects the frequency from the key fob
- It boosts the transmission power
- The boosted transmission is sent to the target automobile
- The vehicle validates the signal
- Access is granted as if the key fob were in proximity
