EFFI is a powerful and professional modular software solution for automotive locksmiths. This comprehensive package, version 2.7.2, comes with a massive set of 173 modules, enabling an incredible range of functions. It covers everything from simple key copying and identification to advanced transponder generation directly from immobilizer memory dumps, as well as low-level chip editing for expert use.
Core Capabilities
• Key Generation from Dump (Image Generator): The software's "Image Generator" is its most powerful feature. It allows you to create new transponder keys in "all keys lost" situations by loading a memory dump file from the vehicle's immobilizer module. It supports a huge range of systems, including BMW CAS1/CAS2/CAS3, Mercedes, Chevrolet, VAG, and many more.
• Transponder Copying & Preparation: The "Copying keys" tab provides a comprehensive set of tools for reading, writing, and copying a wide variety of transponder chips, including Temic, Megamos, and Philips Crypto types.
• Low-Level Transponder Editing: For advanced users, EFFI provides direct, low-level access to the memory of specific transponder types. There are dedicated tabs for working with Hitag II, PCF7935, and Megamos Crypto chips, allowing you to read and write individual memory pages and blocks.
• PIN Code Calculation: Includes modules to calculate immobilizer PIN codes from vehicle memory dumps, such as for Kia and Hyundai vehicles.
• Transponder Cross-Reference: A built-in database to find compatible replacement transponder chips. It cross-references transponder names with equivalents from brands like Zed-BULL, RW4, and JMA.
