Guides & Answers

Plain-language guides to automotive module programming, written by the mobile lab that does the work in Atlanta and Georgia. Every guide ends with how to get it done without a tow or a dealer visit.

  1. U0100 Code: What It Means and What It Costs to Fix

    Lost communication with the ECM/PCM is usually battery, wiring, or fuses — not a dead module. Causes in order, real costs, and what to check before paying anything.

  2. Can You Swap a Used ECM Without Programming It?

    A junkyard ECM won’t start your car without VIN programming and immobilizer relearn. What a used module actually needs, and the cheaper cloning alternative.

  3. Mobile Mechanic vs Dealer for Module Programming

    The honest comparison: same tools, same procedure, and prices published before you call. When the dealer is actually required, and the one question to ask any mobile programmer.

  4. Is It Safe to Program a Car Computer in a Driveway?

    Yes — programming is software. What really determines safety (voltage, tools, technician), the red flags to walk away from, and what a pro does before starting.

  5. What Is Mobile Module Programming? The Complete Guide

    Services, 4-step process, real costs ($185–$800), and who it’s for. The pillar guide to mobile automotive module programming.

If your question is not here, call and ask it. Year, make, model and the symptom is usually enough for us to tell you whether this is a programming job, a wiring fault or something else entirely.
