Car Key Signal Repeater: Complete Guide
What is a Key Repeater Device?
A keyless entry repeater is a device that extends the transmission from your key fob. This technology allows remote access to vehicles equipped with smart key technology.
Repeater systems are commonly used for authorized use such as vehicle testing and security assessments.
How Does a Repeater Device Work?
The repeater system works by receiving the LF signal from your key fob and sending it to your vehicle. Here’s the mechanism:
- The repeater device picks up the signal from the remote
- It strengthens the transmission power
- The boosted transmission is relayed to the vehicle
- The automobile validates the signal
- Entry is permitted as if the key were nearby
