Code Grabber: Everything You Need to Know
What is a Code Grabber?
A car code grabber is a specialized device designed to capture rolling codes transmitted between a vehicle remote and the car’s receiver. This technology is commonly employed for automotive testing and system analysis.
Code grabber devices are compatible with multiple vehicle brands and encryption systems.
How Does a Code Interceptor Work?
The grabber device operates by intercepting the radio frequency between your vehicle key and the automobile. Here’s the working mechanism:
- The interceptor listens to the RF spectrum used by key fobs
- When a transmission occurs, the device captures the transmission
- The intercepted signal is stored in the internal storage
- The code can be decoded or sent later
- Advanced models can decrypt encrypted signals
