The SBB V46.02 key programmer is a universal key programmer that can program keys for many vehicle brands. It works by inserting a blank key, connecting the SBB interface to the car's OBD2 port, and following the on-screen instructions to copy the chip code from the car's immobilizer and program it into the new key. The SBB V46.02 can program keys for newer vehicle models than previous versions and also supports firmware updates via an added RS232 cable.
