Keyless Entry Repeater: Complete Guide

What is a Key Repeater Device?

A car key repeater is a equipment that amplifies the radio frequency from your car key fob. This system allows remote access to vehicles equipped with smart key technology.

Key signal repeaters are commonly used for legal applications such as vehicle testing and security assessments.

How Does a Keyless Repeater Work?

The keyless repeater works by receiving the LF signal from your car key and transmitting it to your car. Here’s the process:

1. The signal repeater picks up the signal from the key fob
2. It amplifies the radio frequency
3. The boosted transmission is transmitted to the target automobile
4. The automobile authenticates the signal
5. Entry is permitted as if the key fob were close
