How LockNCal Works
Two ways we help — a nationwide mail-in airbag reset, and on-site mobile service across DFW. Here’s exactly how each one works, and how to book it.

We built our process around a straight answer on price and never making you haul your car anywhere. Whether you’re across the country or across town, here’s what to expect.
What you can count on either way
- 💲 Price up front — See your starting price before you commit — no surprises.
- 📦 Free 2-way shipping (mail-in) — We pay shipping both ways on mail-in resets — the thing that sets us apart nationwide.
- 🚗 We come to you (on-site) — Mobile across Dallas–Fort Worth — no tow, no dealership wait.
- 🛡️ 30-day labor warranty — If our workmanship isn’t right, we make it right.
📦 How mail-in airbag module reset works
If your airbag light is on after a collision, you almost certainly don’t need a new module — you need the crash data cleared. Here’s the whole process, nationwide:
- Book online. Start your mail-in reset and send us your VIN so we can confirm we cover your module.
- Send us the module. Remove your SRS airbag control module and ship it to us with our prepaid label — shipping is on us.
- We reset the crash data. We clear the stored crash data and hard codes, returning the module to its original factory condition.
- We send it back. Most modules are back in the mail within 24 business hours — free return shipping, ready to plug in.
- Install and go. Reinstall the module, the airbag light is off, and your vehicle is good to go.
Free 2-way shipping. Usually a 24 business-hour turnaround. Just $49.99.
