Vehicle Code Grabber: Everything You Need to Know
What is a Code Grabber?
A car code grabber is a electronic equipment designed to record encrypted signals transmitted between a remote key and the car's receiver. This device is commonly employed for security research and professional diagnostics.
Code grabber devices are compatible with various vehicle brands and rolling code algorithms.
How Does a Car Code Grabber Work?
The interceptor system works by capturing the wireless transmission between your vehicle key and the automobile. Here's the working mechanism:
- The code grabber listens to the radio bands used by vehicle keys
- When a transmission occurs, the device captures the transmission
- The intercepted signal is stored in the internal storage
- The transmission can be decoded or replayed later
- Professional devices can decode security algorithms
