Car Key Signal Repeater: Everything You Need to Know
What is a Keyless Entry Repeater?
A keyless repeater is a device that extends the transmission from your key fob. This system allows remote access to vehicles equipped with smart key technology.
Keyless repeater devices are commonly used for legal applications such as automotive diagnostics and vulnerability analysis.
How Does a Keyless Repeater Work?
The keyless repeater works by receiving the radio signal from your car key and broadcasting it to your vehicle. Here’s the working principle:
- The repeater device receives the signal from the key fob
- It amplifies the transmission power
- The boosted transmission is relayed to the vehicle
- The vehicle recognizes the signal
- The car unlocks as if the key fob were nearby
