Keyless Repeater: Everything You Need to Know
What is a Keyless Repeater?
A car key repeater is a equipment that boosts the radio frequency from your car key fob. This system allows remote access to vehicles equipped with smart key technology.
Keyless repeater devices are commonly used for authorized use 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 sending it to your vehicle. Here’s the working principle:
- The keyless repeater picks up the signal from the key fob
- It boosts the transmission power
- The boosted transmission is transmitted to the car
- The car recognizes the signal
- The car unlocks as if the key were nearby
