Keyless Entry Repeater: Everything You Need to Know

What is a Keyless Repeater?

A keyless entry repeater is a device that amplifies the signal from your car key fob. This technology allows wireless entry to cars equipped with smart key technology.

Repeater systems are widely utilized for authorized use such as automotive diagnostics and security assessments.

How Does a Repeater Device Work?

The repeater system works by detecting the radio signal from your car key and broadcasting it to your automobile. Here’s the working principle:

1. The repeater device detects the signal from the remote
2. It boosts the transmission power
3. The boosted transmission is transmitted to the vehicle
4. The automobile recognizes the transmission
5. The car unlocks as if the remote were nearby
