Keyless Entry Repeater: Complete Guide
What is a Keyless Entry Repeater?
A keyless repeater is a device that amplifies the signal from your key fob. This device allows wireless entry to vehicles equipped with smart key technology.
Key signal repeaters are frequently employed for authorized use such as automotive diagnostics and penetration testing.
How Does a Repeater Device Work?
The signal amplifier works by capturing the LF signal from your remote key and transmitting it to your car. Here’s the process:
- The signal repeater receives the signal from the car key
- It amplifies the signal strength
- The amplified signal is relayed to the vehicle
- The vehicle recognizes the transmission
- Entry is permitted as if the key were nearby
