Does it need programming—or a diagnosis?

Common service questions
Clear expectations help you avoid an unnecessary service call.
Can you program a used module?
We support compatible used modules for many applications. Send the VIN and photos of both module labels before purchasing or scheduling. Support depends on the specific vehicle and module; matching part numbers alone may not be enough. Read about used module programming.
My car will not start. Should I book programming?
If the cause has not been diagnosed, start with a diagnostic appointment. Power, wiring and communication faults can look like a failed computer. See no-crank and no-start diagnostics.
Do you come to automotive repair shops?
Yes. Mobile service is available by appointment across Houston and surrounding areas. Send the vehicle details, shop location, requested service and work already completed. See programming for repair shops.
What should I send for a quote?
Send the year, make, model, VIN, symptoms, fault codes and your ZIP code. For replacement modules, include clear photos of the original and replacement labels and tell us whether the part is new or used. Request a quote.
