Launch X-PROG 3 – Advanced Key & ECU Programmer for Launch X431 Devices
Professional IMMO, Key Programming, EEPROM/MCU Read-Write & ECU/TCU Bench Access
The Launch X-PROG 3 is a professional-grade key programmer and immobiliser data unit, designed for full integration with Launch X431 diagnostic devices.
It enables key programming, ECU and TCU cloning, PIN and ISN code extraction, EEPROM/MCU data processing, and IMMO system repair – all without the need to dismantle or desolder components from the vehicle’s control units.
Built for professionals, X-PROG 3 turns your compatible Launch tablet into a complete IMMO workstation, capable of handling EEPROMs, MCUs, ECUs, instrument clusters, and smart keys.
It supports major global brands such as BMW, Mercedes-Benz, VW, Audi, Škoda, SEAT, Toyota, Hyundai, Ford, Renault, Peugeot, Citroën, and many more.
Ideal for locksmiths, IMMO specialists, and diagnostic workshops, it allows secure data handling through Bench/Boot connections and full anti-theft synchronization between ECUs and IMMO modules.
⚙️ KEY FEATURES AND FUNCTIONS
🧠 1. EEPROM READ & WRITE
EEPROM (Electrically Erasable Programmable Read-Only Memory) chips store vehicle data like PIN codes, IMMO info, odometer values, and serial numbers.
With X-PROG 3, you can safely read and write these memory chips without removing or desoldering components.
✅ Supported EEPROM families: 24Cxx, 93Cxx, 95xxx, etc.
✅ Typical applications: Renault UCH, Peugeot/Citroën BSI, VW dashboards, Toyota IMMO boxes
✅ Connection method: Via chip socket adapter or Bench harness
⚙️ 2. MCU READ & WRITE
MCU (Microcontroller Unit) chips manage internal operations in modules such as ECU, BCM, ESL, or IMMO.
X-PROG 3 accesses these controllers to extract or modify data directly through MCU adapters or Bench cables, eliminating the need for risky board soldering.
✅ Supported MCU brands: Motorola, ST, Renesas, Infineon, NEC, Fujitsu
✅ Applications: Mercedes ESL/ELV, BMW CAS4+/FEM/BDC, VAG MQB, Toyota Smart Box
✅ Modes: Boot or Bench (depending on module type)
🔑 3. KEY PROGRAMMING & SIMULATION
X-PROG 3 supports advanced automotive key programming, including:
Key generation and learning, even in All Keys Lost scenarios
Smart key and remote learning (Start/Stop, Keyless Go systems)
Mercedes IR key simulation via the included infrared adapter
✅ Supports transponder creation and smart key generation
✅ Compatible with Launch IMMO software for guided key learning
✅ Allows synchronization of new keys to the IMMO and ECU modules
🔐 4. ANTI-THEFT & COMPONENT CLONING
X-PROG 3 reads, copies, and transfers security and configuration data between modules — perfect for replacing or cloning ECUs, BSI, or instrument clusters.
✅ Read & write PIN / ISN codes
✅ Clone ECUs, BCMs, dashboards, and IMMO modules
✅ Replace defective components without recoding
✅ Fully supports MQB, CAS, FEM, UDS, and ELV architectures
⚙️ 5. BENCH / BOOT ECU & TCU ACCESS
X-PROG 3 enables non-invasive data reading and writing directly from engine and transmission ECUs.
✅ Bench mode: Direct ECU connection via external harness – no need to open the case
✅ Boot mode: Access protected ECUs requiring secure boot pin connection
✅ Supported units: BMW 8HP, VW DSG (0AW/0B5), Audi OAW, UDS engine ECUs
This ensures complete coverage for module cloning, replacement, or data repair operations.
