Car Key Signal Repeater: Everything You Need to Know
What is a Keyless Entry Repeater?
A car key repeater is a tool that boosts the transmission from your car key fob. This system allows remote access to automobiles equipped with keyless entry systems.
Repeater systems are frequently employed for legitimate purposes such as automotive diagnostics and vulnerability analysis.
How Does a Repeater Device Work?
The repeater system works by receiving the LF signal from your key fob and sending it to your automobile. Here’s the mechanism:
- The signal repeater receives the transmission from the key fob
- It strengthens the radio frequency
- The boosted transmission is sent to the vehicle
- The car authenticates the signal
- The car unlocks as if the key were in proximity
