4. Operating Instructions
The Zed-Bull device offers a range of functions for key transponder programming and cloning. Its wide graphic LCD screen provides detailed information for ease of use.
4.1 Transponder Cloning
The device supports cloning for various transponder types, including:
- 11, 12, 13, 33, 73
- 4C (writing to 4C electronic key and battery-less TPX1 transponder)
- Crypto 40 (some), 41 (all), 42 (all), 44 (all unlocked), 45 (all)
Unlike older tools, the Zed-BULL can copy transponders like 41, 42, 44 (Unlocked), and 45 (PEUGEOT) which were previously considered non-copyable.
4.2 PIN Code Reading
The Zed-Bull is capable of reading PIN codes for Hyundai and Kia vehicles.
4.3 Transponder Production for OBD Programming
For OBD devices requiring special precoded transponders, the Zed-Bull allows you to produce them using blank transponders. This eliminates the need to purchase expensive precoded transponders. Supported transponder types for production include:
- 40, 41, 42, 44, 45, 73 Mitsub, 61, 62, 65
- 46 for BMW, PORSCHE, CHRYSLER, RENAULT, etc.
The device currently supports 24 different transponder production applications.
4.4 Hitag2 Transponder Programming
The Zed-Bull includes a Hitag2 programmer feature, allowing you to work with Hitag2 transponders without needing a separate device.
4.5 Advanced Features
- Automatic Module Finding (AMF): Automatically recognizes the module when an EEPROM file is selected.
- Wide Graphic LCD Screen: Displays detailed information such as VIN number and kilometer info for BMW cars, and detailed information for 46 and 48 transponders.
- 8C and 8E Chip Support: Features a function to distinguish between 8C and 8E chips.
- Improved Speed and Success Rate: The Smart Zed-Bull model offers 30% faster reading and writing speed and an improved success rate of up to 99.99%, reducing chip waste.
