Car Code Grabber: Everything You Need to Know

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 device is primarily used for security research and penetration testing.

Code interceptors support different vehicle brands and encryption systems.

How Does a Code Interceptor Work?

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

1. The code grabber listens to the radio bands used by car remotes
2. When a signal is detected, the interceptor intercepts the code
3. The recorded transmission is saved in the device memory
4. The transmission can be decoded or sent later
5. Premium grabbers can decrypt encrypted signals
