Keyless Entry Repeater: Complete Guide
What is a Keyless Entry Repeater?
A car key repeater is a tool that boosts the radio frequency from your car key fob. This technology allows remote access to automobiles equipped with keyless entry systems.
Keyless repeater devices are commonly used for authorized use such as automotive diagnostics and vulnerability analysis.
How Does a Keyless Repeater Work?
The keyless repeater works by detecting the low-frequency signal from your remote key and transmitting it to your automobile. Here’s the working principle:
- The keyless repeater picks up the transmission from the car key
- It amplifies the transmission power
- The enhanced frequency is sent to the car
- The car recognizes the signal
- The car unlocks as if the remote were in proximity
