Keyless Entry Repeater: Everything You Need to Know

What is a Keyless Repeater?

A keyless repeater is a equipment that amplifies the signal from your car key fob. This technology allows remote access to vehicles equipped with smart key technology.

Key signal repeaters are widely utilized for legal applications such as car security research and security assessments.

How Does a Key Signal Repeater Work?

The keyless repeater works by capturing the LF signal from your remote key and sending it to your automobile. Here’s the mechanism:

1. The signal repeater detects the signal from the remote
2. It boosts the radio frequency
3. The enhanced frequency is transmitted to the vehicle
4. The vehicle authenticates the transmission
5. The car unlocks as if the remote were close
