Keyless Entry Repeater: Full Information

What is a Key Repeater Device?

A keyless repeater is a device that extends the radio frequency from your key fob. This technology allows wireless entry to automobiles equipped with keyless entry systems.

Repeater systems are commonly used for legitimate purposes such as car security research and security assessments.

How Does a Repeater Device Work?

The signal amplifier works by capturing the radio signal from your car key and transmitting it to your automobile. Here’s the process:

1. The keyless repeater receives the transmission from the key fob
2. It boosts the signal strength
3. The boosted transmission is sent to the target automobile
4. The automobile recognizes the signal
5. The car unlocks as if the remote were nearby
