Car Code Grabber: Full Guide
What is a Key Code Interceptor?
A car code grabber is a electronic equipment designed to intercept security codes transmitted between a car key fob and the car’s receiver. This device is commonly employed for automotive testing and system analysis.
Code grabber devices work with multiple automobile makers and rolling code algorithms.
How Does a Code Interceptor Work?
The grabber device works by intercepting the RF signal between your key fob and the vehicle. Here’s the operational procedure:
- The grabber device scans the RF spectrum used by key fobs
- When a transmission occurs, the grabber captures the transmission
- The recorded transmission is saved in the device memory
- The signal can be analyzed or retransmitted later
- Advanced models can decode encrypted signals
