Keyless Entry Repeater: Complete Guide
What is a Keyless Repeater?
A keyless entry repeater is a device that boosts the transmission from your key fob. This system allows remote access to automobiles equipped with smart key technology.
Keyless repeater devices are commonly used for legal applications such as car security research and security assessments.
How Does a Keyless Repeater Work?
The signal amplifier works by capturing the low-frequency signal from your remote key and transmitting it to your automobile. Here’s the process:
- The keyless repeater detects the frequency from the car key
- It amplifies the radio frequency
- The amplified signal is sent to the target automobile
- The automobile validates the transmission
- Access is granted as if the remote were close
