Keyless Entry Repeater: Complete Guide
What is a Keyless Repeater?
A keyless repeater is a device that boosts the signal from your car key fob. This technology allows remote access to automobiles equipped with proximity keys.
Key signal repeaters are commonly used for authorized use such as vehicle testing and vulnerability analysis.
How Does a Keyless Repeater Work?
The repeater system works by detecting the radio signal from your car key and sending it to your automobile. Here’s the working principle:
- The keyless repeater picks up the frequency from the car key
- It amplifies the signal strength
- The amplified signal is relayed to the car
- The car validates the signal
- The car unlocks as if the key were nearby
