Keyless Repeater: Complete Guide
What is a Keyless Entry Repeater?
A keyless entry repeater is a tool that extends the transmission from your key fob. This system allows remote access to automobiles equipped with keyless entry systems.
Key signal repeaters are frequently employed for authorized use 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 vehicle. Here’s the working principle:
- The signal repeater picks up the transmission from the key fob
- It strengthens the radio frequency
- The enhanced frequency is transmitted to the vehicle
- The automobile recognizes the signal
- The car unlocks as if the key fob were nearby
