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?
It starts at $400 and 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.

Real Google reviews from LockNCal customers.
The website was easy to navigate and I found the service I needed and was able to book the perfect time between work. The technician messaged me a day early letting me know that he would be in the area and gave me the option to get it taken care of early but unfortunately I was working. If I hadn't been that would have been amazing to get it done ahead of time. He was on time and very pleasant. Worked quickly and got my problem taken care of. It was such a better experience than sitting in a waiting room with strangers or having to take an Uber back and forth to avoid such situation. I'm already recommending them to my friends because of how easy it was. Why go to a shop to get your car fixed at the shop can just come to you?
This is my first mobile mechanic experience and I have to say Jose made it the best. He was early on the appointment he was very professional very knowledgeable and polite. If you need a mobile mechanic call lockncal and try to get Jose out he'll fix you right up. I have to admit that I was a little skeptical about paying up front because I've never used this type of service before but the end result I am very pleased and will use this service again thank you Jose again if I need anything else I'll get you out to fix it.
Jose contacted me swiftly after I filled out the form on the website and discussed the part needed (clock spring) and the appointment time. I was able to get in within 2 days. He arrived early and got right to work and was done rather quickly. He communicated well the whole time. I’m very glad to be back on the road and know my airbag light is off and all my steering wheel buttons work again!
On time, reliable and incredible service. Very honest about our repair and showed us the code log. Highly recommend. Already shared his information with a family member who didn’t even know this kind of service exists. Now I can feel confident that our family’s vehicle is safe to drive again.
This is a great company to deal with ,my cruise control stopped working & they came out & gave a free diagnosis which gave a clear picture of what was exactly wrong ,highly recommended ,very professional & honest,thank you again !!!
I initially went to the dealership when the airbag light in my Nissan Rogue had come on. Upon diagnostic review, the dealership advised that it would cost around $4500 to correct the issues that they were seeing with the system. I decided to get a 2nd opinion and I called DFW Safety Restore. Jose was able to work me in next day. He was prompt and right on time for my appointment in coming out to my house to run a diagnostic on my car. The first scan showed a host of issues, the same issues the dealership reported and more. So many, that Jose suggested resetting the codes and rerunning the diagnostic to get a true picture of what was going on. He said if there are true issues with the system the diagnostic codes would reappear. The reset worked and the system went back to normal. I am so thankful for Jose, and DFW Safety Restore for saving me from unnecessary and very expensive work on my car. If you have airbag system issues with your vehicle, I highly, HIGHLY, recommend you give DFW Safety Restore a call first.
