The situation.
A replacement control module may need programming, coding or setup before it can operate correctly in the vehicle. Those steps are different from simply adding a key. A warning message or no-start condition also needs assessment before a module is treated as the cause.
The approach to your vehicle.
We review the exact model and year, module identity, original symptoms and any previous repairs. For supported vehicles and units, we confirm the programming or setup required, the parts involved and the proposed price before work begins. Keep the original module available when possible.
Questions about module programming.
Is module programming the same as key programming?
No. Key programming establishes the appropriate key functions for the vehicle. Module programming, coding or setup concerns an electronic control unit. The correct procedure depends on the vehicle and the specific unit.
Can you program a used replacement module?
Eligibility depends on the vehicle, module type, part compatibility and previous configuration. Have those details checked before buying a used unit; some cannot be reused for the intended job.
Which European systems can I ask about?
Ask about Mercedes ignition and steering locks, BMW access modules, JLR KVM/RFA, Audi/VW immobilizer systems, Volvo CEM and other European vehicle modules. Exact model, year and unit determine support.
Will programming fix any no-start or warning light?
No. Programming is appropriate only when the assessed condition calls for it. A power supply, wiring, mechanical or unrelated electronic fault may need a different repair.
