Vehicle Code Grabber: Full Guide

What is a Key Code Interceptor?

A code grabber is a specialized device designed to capture rolling codes transmitted between a vehicle remote and the vehicle system. This equipment is commonly employed for automotive testing and penetration testing.

Code interceptors are compatible with various vehicle brands and encryption systems.

How Does a Code Grabber Work?

The interceptor system operates by recording the wireless transmission between your vehicle key and the car. Here’s the working mechanism:

1. The interceptor monitors the frequency range used by car remotes
2. When a signal is detected, the grabber captures the signal
3. The captured code is logged in the data buffer
4. The signal can be examined or retransmitted later
5. Professional devices can decrypt rolling codes
