Keyless Entry Repeater: Full Information

What is a Key Repeater Device?

A keyless repeater is a device that amplifies the transmission from your vehicle remote. This system allows keyless entry to vehicles equipped with proximity keys.

Keyless repeater devices are frequently employed for authorized use such as automotive diagnostics and security assessments.

How Does a Keyless Repeater Work?

The signal amplifier works by detecting the low-frequency signal from your key fob and transmitting it to your automobile. Here’s the mechanism:

1. The keyless repeater receives the signal from the car key
2. It strengthens the radio frequency
3. The amplified signal is transmitted to the target automobile
4. The automobile validates the key signature
5. Access is granted as if the key fob were close
