Code Grabber: Everything You Need to Know

What is a Code Grabber?

A car code grabber is a specialized device designed to record rolling codes transmitted between a car key fob and the automobile security. This equipment is commonly employed for vulnerability assessment and penetration testing.

Code interceptors work with different car manufacturers and encryption systems.

How Does a Code Grabber Work?

The interceptor system operates by intercepting the radio frequency between your vehicle key and the vehicle. Here’s the detailed process:

1. The grabber device listens to the frequency range used by car remotes
2. When a signal is detected, the interceptor intercepts the transmission
3. The recorded transmission is logged in the internal storage
4. The signal can be decoded or retransmitted later
5. Premium grabbers can decode encrypted signals
