Keyless Repeater: Everything You Need to Know

What is a Key Repeater Device?

A keyless entry repeater is a device that extends the transmission from your car key fob. This system allows keyless entry to automobiles equipped with keyless entry systems.

Keyless repeater devices are frequently employed for legitimate purposes such as vehicle testing and security assessments.

How Does a Repeater Device Work?

The keyless repeater works by detecting the radio signal from your key fob and transmitting it to your vehicle. Here’s the process:

1. The repeater device receives the transmission from the remote
2. It amplifies the transmission power
3. The boosted transmission is relayed to the vehicle
4. The automobile recognizes the signal
5. Entry is permitted as if the remote were close
