Authorised mobile immobiliser support
ECU immobiliser programming and permitted Immo Off service
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.
Diagnostic-led non-start repair
Power, wiring, communication, key recognition and module data are checked before software changes.
ECU compatibility checks
ECU labels, hardware and software references are assessed before replacement programming or data transfer.
Authorised repair assessment
Vehicle identity, ownership and intended use are verified before work on security-related software.
Vehicle key programming and locksmith support
Car key programming, replacement keys and vehicle locksmith services
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.

Immobiliser ECU cloning service by post
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.

Send labels first
Provide the VIN and clear photographs of the original and donor modules.
02
Compatibility check
Hardware, software, part numbers, memory condition and security generation are assessed.
03
Controlled data transfer

Secure digital file assessment
Online immobiliser delete and removal file service
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.
Original ECU read
Supply the complete unmodified OBD, bench or boot read with ECU IDs and tool details.
Vehicle and fault information
VIN, engine code, ECU label, diagnostic report, replacement history and intended lawful use.
Compatibility before payment
Not every ECU or security generation supports a safe file solution; suitability is confirmed first.
Authorised security-data service
Immobiliser PIN code and ECU/BCM security-data retrieval
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.
Proof required before security work
We require photo identification, proof of vehicle ownership or written trade authority, VIN and module-origin details. We do not provide security data where identity, ownership or intended use cannot be verified.
Ownership and lawful use
All immobiliser, key, PIN and security-module services require proof of ownership or written authority. We do not assist with unauthorised access, stolen vehicles, concealment of vehicle identity or circumvention intended to facilitate theft.

Before you book
Frequently asked questions
What can cause an immobiliser-related non-start?
Possible causes include an unrecognised key, transponder or antenna fault, lost synchronisation, incompatible replacement ECU or BCM, damaged wiring, low voltage, CAN communication failure, corrupt module data or an unrelated engine-management fault. Diagnosis is required before programming.
Can you clone an ECU with immobiliser data?
Selected readable ECUs can be cloned to an exact or approved compatible donor by transferring supported software, coding, VIN and authorised immobiliser data. Compatibility depends on the controller hardware, software, memory condition and security generation.
Do you support BMW and MINI CAS and ISN programming?
Supported BMW and MINI DME/DDE, CAS, FEM and BDC systems can be assessed for authorised ECU replacement, ISN matching, module data transfer and key coding. Coverage depends on chassis, model year, module generation and secure access.
Is mobile immobiliser programming available around Birmingham?
Selected vehicle-side diagnostics and programming may be available in Stourbridge, Birmingham, Dudley, Halesowen, Wolverhampton, Walsall, Solihull, West Bromwich, Kidderminster, Bromsgrove and Coventry, with wider UK attendance by arrangement.
Can immobiliser or ECU modules be sent by post?
Approved modules can be sent by tracked courier from England, Scotland, Wales, Northern Ireland, Republic of Ireland and Europe, with worldwide enquiries by arrangement. Vehicle details, diagnostic information, label photographs and ownership evidence are required first.
Can you retrieve an immobiliser PIN or security code?
Selected vehicle and module generations support authorised PIN or security-data retrieval for legitimate repair and programming. Proof of identity, vehicle ownership or written trade authority is required, and some newer systems require manufacturer-controlled access.
What should I do if the immobiliser warning light stays on?
Avoid buying a replacement ECU or key solely from a warning light. A diagnostic check should distinguish key recognition, supply, antenna, module communication and security matching faults.
Can I send an immobiliser module without proof of ownership?
For security-related services, SGTM may ask for identification, registration, VIN and evidence that you own or are authorised to repair the vehicle.
Need a diagnosis or quotation?
Send the registration, VIN, engine code and module-label photos
