Keyless Entry Repeater: Full Information
What is a Keyless Entry Repeater?
A keyless repeater is a equipment that extends the radio frequency from your car key fob. This system allows wireless entry to vehicles equipped with smart key technology.
Key signal repeaters are widely utilized for legitimate purposes such as car security research and vulnerability analysis.
How Does a Repeater Device Work?
The keyless repeater works by capturing the low-frequency signal from your remote key and sending it to your car. Here's the process:
- The signal repeater receives the frequency from the key fob
- It boosts the radio frequency
- The boosted transmission is transmitted to the target automobile
- The vehicle authenticates the signal
- Entry is permitted as if the key were nearby
