Code Grabber: Full Guide
What is a Key Code Interceptor?
A code grabber is a technical tool designed to capture rolling codes transmitted between a car key fob and the automobile security. This equipment is typically utilized for security research and professional diagnostics.
Code interceptors support different automobile makers and security protocols.
How Does a Code Grabber Work?
The code grabber operates by intercepting the wireless transmission between your key fob and the vehicle. Here’s the detailed process:
- The interceptor scans the frequency range used by key fobs
- When a transmission occurs, the grabber captures the transmission
- The captured code is logged in the internal storage
- The signal can be decoded or retransmitted later
- Premium grabbers can decrypt security algorithms
