Keyless Repeater: Complete Guide
What is a Keyless Repeater?
A keyless entry repeater is a device that boosts the transmission from your car key fob. This technology allows wireless entry to cars equipped with proximity keys.
Key signal repeaters are widely utilized for authorized use such as vehicle testing and penetration testing.
How Does a Key Signal Repeater Work?
The signal amplifier works by receiving the radio signal from your remote key and sending it to your vehicle. Here’s the working principle:
- The signal repeater detects the signal from the remote
- It strengthens the transmission power
- The boosted transmission is sent to the vehicle
- The vehicle authenticates the signal
- The car unlocks as if the key were close
