Launch X431 X-PROG 3 – Advanced IMMO & Key Programming Device

X-PROG 3 significantly expands the capabilities of a compatible Launch X431 scanner beyond conventional vehicle diagnostics. It adds professional IMMO and key programming, EEPROM and MCU data processing, supported ECU read/write operations, security-data handling, PIN/ISN-related functions, module replacement support, and advanced Bench/Boot access. For workshops already using the Launch X431 ecosystem, it provides a practical way to build a more complete key, immobilizer, and automotive electronics programming workstation.

The X-PROG 3 is designed primarily for professional automotive locksmiths, immobilizer specialists, auto electricians, ECU technicians, diagnostic workshops, and automotive electronics professionals who require advanced access to vehicle security and control-module data.

No. Key programming, All Keys Lost, EEPROM/MCU read and write, PIN/ISN extraction, ECU/TCU operations, Bench/Boot access, module replacement, and other advanced functions depend on the vehicle manufacturer, model, production year, immobilizer system, ECU/module type, chip, required adapters, and current Launch software coverage.

X-PROG 3 is compatible with selected Launch professional diagnostic platforms, including supported versions of X431 PAD VII, PAD V, PRO5, PRO3S+, V/V+, PROS, PROS MINI, Diagun V, PAD III V2.0, PRO GT, and other compatible X431 devices. Exact compatibility should be confirmed for the specific tablet and hardware version.

No. Many supported procedures can be performed through OBD, Bench, Boot, direct harnesses, sockets, or dedicated adapters without desoldering the memory chip. However, some chip-level applications may require direct access to the circuit board or specific components, so the required method depends on the module.

Yes. Supported modules can be accessed using direct connection methods such as Bench or Boot, depending on the ECU, TCU, MCU, or other control module. The required connection method and wiring must always follow the applicable Launch connection diagram.

X-PROG 3 supports selected ECU and TCU data operations, while broader PC-based ECU/TCU cloning capabilities can be added using compatible Launch expansion hardware such as the X-PROG3 PC Adapter. Exact cloning coverage depends on the ECU/TCU model and current Launch software.

Yes. X-PROG 3 supports ECU data reading and writing for selected supported control units. This can be used for data backup, restoration, immobilizer-related operations, module replacement, and other advanced automotive electronics procedures.

Yes. Selected VAG immobilizer applications are supported, including functions involving compatible Volkswagen, Audi, Škoda, and SEAT keys, instrument clusters, ECUs, and anti-theft systems. Exact MQB and other platform coverage depends on the vehicle and software version.

Yes. X-PROG 3 supports selected Mercedes-Benz key and immobilizer applications. It can work with supported Mercedes-Benz infrared smart-key systems and includes functionality for reading compatible IR smart-key data and performing applicable IMMO procedures.

Yes. X-PROG 3 supports selected BMW immobilizer and module applications, including supported CAS4+, FEM/BDC, DME, and related systems. Available procedures can include security-data reading, key-related operations, module matching, and other supported IMMO functions.

Yes. PIN, ISN, and other security-data operations are available for selected supported vehicle systems. For example, X-PROG 3 supports selected BMW applications involving engine ISN data used during immobilizer and module synchronization procedures.

Yes, All Keys Lost functions are available for selected supported vehicles. Coverage depends on the manufacturer, model, production year, immobilizer generation, ECU configuration, key type, required adapters, and current Launch software.

Yes. Key and immobilizer programming are major applications of the X-PROG 3. When used with a compatible Launch X431 platform, it can assist with supported key learning, key generation, immobilizer matching, security-data processing, and related IMMO procedures.

Yes. X-PROG 3 supports read/write operations on selected automotive microcontrollers. Supported applications can include MCUs from manufacturers such as Motorola, ST, Renesas, Infineon, NEC, Fujitsu, and others, depending on current software coverage.

X-PROG 3 supports multiple commonly used automotive EEPROM families, including selected 24Cxx, 93Cxx, and 95xxx series chips. Exact chip coverage depends on the current Launch software and the specific adapter or connection method required.

Yes. X-PROG 3 supports reading and writing compatible EEPROM chips used in automotive control modules. These operations can be useful for immobilizer data processing, module replacement, data backup, restoration, and other advanced automotive electronics procedures.

Depending on the vehicle and module, X-PROG 3 can support key and immobilizer programming, transponder operations, EEPROM reading and writing, MCU/ECU data reading and writing, security-data processing, PIN/ISN-related operations, module replacement procedures, and selected ECU/TCU cloning applications.

No. The X-PROG 3 is not a standalone diagnostic or programming device. It is designed to operate with a compatible Launch X431 diagnostic tablet and the appropriate Launch software. Compatibility should be verified for the exact X431 model before purchase.

The Launch X431 X-PROG 3 is a professional immobilizer, key, EEPROM, MCU, ECU, and automotive module programming device designed to work with compatible Launch X431 diagnostic tablets. It expands a supported X431 platform with advanced IMMO programming, key-related functions, security-data processing, and module read/write capabilities.
