Car Key Signal Repeater: Full Information
What is a Key Repeater Device?
A keyless repeater is a device that amplifies the transmission from your vehicle remote. This technology allows wireless entry to cars equipped with proximity keys.
Keyless repeater devices are widely utilized for legal applications such as car security research and penetration testing.
How Does a Repeater Device Work?
The keyless repeater works by capturing the low-frequency signal from your car key and transmitting it to your vehicle. Here’s the working principle:
- The keyless repeater receives the transmission from the remote
- It strengthens the radio frequency
- The boosted transmission is relayed to the vehicle
- The car authenticates the key signature
- Access is granted as if the key were nearby
