Module Programming in Dallas–Fort Worth
A replacement control module — engine, transmission, body, or ABS — won’t run your car until it’s programmed and coded to your specific vehicle. We flash and code modules on-site across DFW so your replacement part actually works.
Modern cars are run by a network of control modules — the engine computer (ECM/PCM), transmission controller (TCM), body control module (BCM), ABS module, and more. When one fails and gets replaced, the new unit almost never works straight out of the box. It has to be flashed with the correct software and coded to your VIN so it speaks the same language as the rest of the car.
That’s what we do. We program new or replacement modules to your exact vehicle, on-site, so the part you paid for actually functions and the warning lights clear.
When a module needs programming
Programming or coding is required when:
- A control module was replaced — ECM/PCM, TCM, BCM, ABS, and others need coding to your VIN.
- A used module was installed that’s still coded to another vehicle.
- A module needs a software update (reflash) to fix a known fault or drivability issue.
- New keys or components require the module to learn them.

Common questions
Why won’t my replacement module just work when I plug it in?
Because it isn’t yet coded to your car. Replacement modules arrive blank or set for a different VIN, and your vehicle’s network won’t accept one until it’s flashed with the right software and programmed to your VIN. That’s the programming step we handle.
How much does module programming cost?
You’ll see your exact price in about 60 seconds when you book online — it depends on your vehicle and which module. We confirm the price after we know exactly what needs programming.
Can you program a used module from another vehicle?
Often yes — many modules can be recoded to your VIN. Send us the module and your vehicle details and we’ll tell you whether it can be used.
Do you come to me?
Yes — we’re mobile across all of Dallas–Fort Worth.

Jose has been a great help in diagnosing, troubleshooting, and reprogramming the airbags on my 2016 Mazda Miata. I’ve found his pricing to be very competitive, and his turnaround time is quick. Additionally, working with Jose is convenient since he’s mobile.
Excellent service!! Sent my SRS module from FL to have it checked. The day they received it, they had it fixed and mailed back out the very same evening. When I received it, plugged it in and SRS light on dash gone. Thanks LockNCal, very much appreciated!
