Keyless Repeater: Complete Guide
What is a Keyless Entry Repeater?
A keyless repeater is a tool that extends the radio frequency from your car key fob. This system allows remote access to automobiles equipped with proximity keys.
Key signal repeaters are commonly used for authorized use such as automotive diagnostics and vulnerability analysis.
How Does a Repeater Device Work?
The repeater system works by receiving the radio signal from your car key and broadcasting it to your car. Here’s the working principle:
- The repeater device picks up the frequency from the remote
- It amplifies the radio frequency
- The enhanced frequency is sent to the target automobile
- The automobile recognizes the key signature
- The car unlocks as if the key fob were nearby
