✓ Professional equipment

✓ Clear quotation
Specialist support
A correct solution starts with the correct diagnosis.
We support lost keys, spare and replacement keys, remote and transponder learning, key-recognition problems and immobiliser-related crank-no-start faults. Diagnosis may be required because battery voltage, wiring, antennas, body modules, ECU communication and security-system faults can produce similar symptoms.
Our Mobile Car Key & Immobiliser Programming Birmingham workflow is matched to the exact vehicle, controller and software identification rather than relying on a generic assumption. This protects readable original data, confirms compatibility and records the work completed.

Mobile vehicle key specialists
Lost car keys and replacement key programming.
Lost every key or need a reliable spare? We provide mobile key programming for supported cars, vans, motorhomes and pickup trucks. The service may include key cutting, transponder programming, remote or smart-key learning and removal of missing keys from the authorised key list where the vehicle supports it.
Proof of identity, vehicle ownership and authority to request key or immobiliser work is required before security-related services begin.
Mobile key replacement services
Car, van, motorhome and pickup-truck keys.
Vehicle keys can combine a mechanical blade, remote-control electronics, immobiliser transponder, proximity functions and encrypted authorisation. The exact programming method depends on the make, model, year and security generation.
Spare and replacement keys
Add a compatible spare key, replace a damaged key or restore remote and transponder operation after the correct key type is identified.
Van and commercial keys
Mobile key programming for supported work vans, pickups and light commercial vehicles to help reduce unnecessary recovery and downtime.
Motorhome key programming
Key and immobiliser support for compatible motorhomes based on Fiat, Ford, Peugeot, Citroën, Mercedes-Benz, Iveco and other base vehicles.
Remote and smart keys
Remote-control learning, proximity or keyless-start programming and authorised-key checks for compatible vehicle systems.
Key recognition diagnostics
Testing for incorrect-key, antenna, reader, body-module, immobiliser, ECU communication and power-supply faults before programming.
Security-system module services
ECU & immobiliser programming and coding.
Modern start authorisation can involve the engine ECU, immobiliser, instrument cluster, BCM or BSI, electronic ignition switch, steering lock, gateway and key transponder. Replacement modules may require coding, synchronisation, adaptation or supported security-data transfer.
ECU and immobiliser synchronisation
Supported engine ECU and immobiliser modules matched or adapted after correct diagnosis and compatibility checks.
Replacement security-module coding
Configuration of compatible BCM, BSI, CAS, FEM, KESSY, EZS/EIS and related start-authorisation modules where supported.
Transponder and key learning
Compatible chips, remote keys and smart keys programmed into the authorised vehicle security system.
Immobiliser non-start diagnosis
Crank-no-start, key-not-recognised and abnormal security-light symptoms tested before module replacement or programming.

Frequently asked questions
Can you help if all my vehicle keys are lost?
All-keys-lost service is available for supported vehicles after identity, ownership, security-system access and key availability are confirmed. Send the registration, VIN, location and vehicle make, model and year for a compatibility check.
Do you program keys for vans, motorhomes and pickup trucks?
Yes, supported vans, pickups and motorhomes can be assessed. Motorhome coverage is normally determined by the base vehicle, such as Fiat, Ford, Peugeot, Citroën, Mercedes-Benz or Iveco, plus the installed security system.
Can an immobiliser fault stop the engine from starting?
Yes, but a crank-no-start or key warning can also be caused by low voltage, wiring, antennas, body modules, ECU communication or other faults. Diagnostic testing may be required before key or module programming is recommended.
Where is your mobile car-key service available?
Local appointments may be available across Birmingham, Stourbridge, Dudley, Halesowen, Wolverhampton, Walsall, Solihull and surrounding West Midlands areas. National UK attendance is available by arrangement, subject to vehicle and location suitability.
What information do you need?
Please send the registration, VIN, engine code, symptoms and clear photos of relevant module labels.
Is mobile service available?
Mobile attendance depends on the vehicle, location, safe access and technical suitability.
Can you quote from a fault code alone?
A fault code helps us prepare, but it does not always identify the failed component. Diagnostic testing may be required before an accurate repair quotation.
Can I use the online or postal service?
Online file work requires a verified original read and suitable professional tools. Postal work requires clear module-label photographs and approval before shipping. In-vehicle diagnosis cannot be replaced by a file or postal service when physical testing is necessary.
Need a diagnosis or quotation?
Send the registration, VIN, engine code and module-label photos.
