Keyless Entry Repeater: Complete Guide

What is a Keyless Repeater?

A keyless entry repeater is a equipment that amplifies the radio frequency from your car key fob. This technology allows keyless entry to cars equipped with smart key technology.

Key signal repeaters are widely utilized for authorized use such as automotive diagnostics and security assessments.

How Does a Key Signal Repeater Work?

The keyless repeater works by receiving the low-frequency signal from your remote key and transmitting it to your automobile. Here’s the mechanism:

1. The keyless repeater picks up the transmission from the key fob
2. It boosts the transmission power
3. The boosted transmission is sent to the car
4. The automobile validates the signal
5. Entry is permitted as if the key were in proximity
