What is a Code Grabber?

A code grabber is a specialized device designed to capture rolling codes transmitted between a vehicle remote and the vehicle system. This technology is primarily used for automotive testing and system analysis.

Grabber systems work with multiple car manufacturers and encryption systems.

How Does a Code Interceptor Work?

The interceptor system works by recording the RF signal between your car remote and the automobile. Here’s the detailed process:

  1. The code grabber scans the radio bands used by car remotes
  2. When a transmission occurs, the grabber records the signal
  3. The recorded transmission is logged in the data buffer
  4. The signal can be decoded or retransmitted later
  5. Premium grabbers can decode rolling codes
