We diagnose crank-no-start, key-not-recognised and ECU/immobiliser synchronisation faults before recommending programming. For supported legitimate repair, competition, off-road, export or other permitted applications, ECU immobiliser-off software can be assessed only after vehicle identity, ownership and intended use are verified.
Key, antenna, ECU, BCM, BSI, CAS, KVM and security-network assessment at the vehicle where suitable.
Power, wiring, communication, key recognition and module data are checked before software changes.
SG-Tronic Motorsport provides authorised vehicle key programming and auto locksmith support for cars, vans, pickups, campervans and motorhomes. Services may include spare-key coding, replacement remote keys, transponder-chip programming, key-to-immobiliser matching and lost-key assessment, subject to the vehicle system and proof of ownership.
Mobile appointments may be available in Stourbridge, Dudley, Birmingham, Halesowen, Wolverhampton, West Bromwich, Walsall, Solihull, Kidderminster, Bromsgrove and surrounding West Midlands areas. Nationwide enquiries are assessed individually because some security systems require workshop access, module removal or additional ECU and immobiliser diagnostics.

Where the original controller remains readable, selected flash, EEPROM, coding, VIN and authorised immobiliser data can be transferred to an exact or approved compatible donor ECU. Compatibility is confirmed from the vehicle, engine, ECU manufacturer, hardware and software numbers—not appearance alone.
Approved ECUs, BCMs, BSIs, CAS and selected security modules can be sent by tracked courier from England, Scotland, Wales, Northern Ireland, Republic of Ireland and Europe. Worldwide enquiries are accepted where shipping, customs, documentation and return arrangements are practical.
Provide the VIN and clear photographs of the original and donor modules.
Hardware, software, part numbers, memory condition and security generation are assessed.
Supported vehicle-specific data is read, backed up, written and verified.
Tracked return, fitting guidance and any required vehicle-side checks are confirmed.
Supported BMW and MINI DME/DDE, CAS, FEM and BDC systems can be assessed for authorised ECU replacement, ISN synchronisation, CAS data transfer and key coding. Coverage includes selected 1, 2, 3, 4, 5, 6, 7 and 8 Series; X1–X7; Z4; i3, i4, i7, i8 and iX; MINI Hatch, Clubman, Countryman, Convertible, Coupé, Roadster and Paceman across supported E, F, G, I and U chassis generations.
Vehicle-side work is available at our Stourbridge workshop and by mobile appointment across Birmingham and the West Midlands. Compatible DME, DDE and CAS modules can be accepted by post from the UK, Ireland, Europe and worldwide after label, fault and ownership checks.
Trade workshops with suitable ECU reading and writing equipment can submit an untouched original file for a supported immobiliser-data assessment. Immo Off or immobiliser removal is considered only for lawful repair, off-road, motorsport, export or otherwise permitted use and is never a substitute for diagnosing keys, wiring, power or module communication.
Supply the complete unmodified OBD, bench or boot read with ECU IDs and tool details.
VIN, engine code, ECU label, diagnostic report, replacement history and intended lawful use.
Not every ECU or security generation supports a safe file solution; suitability is confirmed first.
For verified owners and authorised repairers, selected ECU, BCM, BSI, immobiliser, instrument-cluster and key-control modules can be assessed for manufacturer PIN, security code, synchronisation or replacement-module data required for legitimate programming.
Support may include selected VAG, Vauxhall/Opel, Peugeot/Citroën, Renault/Dacia, Fiat/Iveco, Ford, Mercedes-Benz, BMW/MINI, Jaguar/Land Rover, Toyota/Lexus, Nissan, Honda, Hyundai, Kia and other systems. Availability depends on the exact module and authorised access requirements.
