Car Key Signal Repeater: Complete Guide
What is a Keyless Repeater?
A car key repeater is a equipment that boosts the transmission from your car key fob. This system allows wireless entry to cars equipped with smart key technology.
Keyless repeater devices are widely utilized for legal applications such as vehicle testing and security assessments.
How Does a Key Signal Repeater Work?
The repeater system works by capturing the LF signal from your car key and sending it to your vehicle. Here’s the process:
- The keyless repeater detects the transmission from the remote
- It boosts the radio frequency
- The boosted transmission is sent to the target automobile
- The car validates the key signature
- Entry is permitted as if the remote were in proximity
