Code Grabber: Everything You Need to Know

What is a Code Grabber?

A vehicle code interceptor is a electronic equipment designed to capture security codes transmitted between a vehicle remote and the car’s receiver. This technology is typically utilized for vulnerability assessment and system analysis.

Grabber systems are compatible with various car manufacturers and rolling code algorithms.

How Does a Car Code Grabber Work?

The grabber device functions by recording the RF signal between your vehicle key and the car. Here’s the operational procedure:

1. The interceptor listens to the RF spectrum used by key fobs
2. When a button is pressed, the device intercepts the code
3. The captured code is saved in the device memory
4. The signal can be analyzed or sent later
5. Premium grabbers can interpret security algorithms
