Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- Lost all keys to a Fiat 500 / 500L / 500X / Abarth
- Fiat no-start immobilizer fault tied to the Body Computer
- Used / donor Body Computer needs setup before install
- Normal key programming isn't possible at the car
- Need a mail-in BCM key solution for a Fiat job
Won't fix:
- Coverage not confirmed for your exact module/year without photos + part number
- Mechanical key-blade or lock faults unrelated to the BCM
- Faulty key fobs / dead batteries
- Body-control faults outside the immobilizer/key data
Before you order
You diagnose, we service the module.
We don't have your car and we don't diagnose it. Order once you or your mechanic have confirmed this module is the cause. If the work is completed and the car still has the same symptom because of another fault, the work is still done — a bench re-test under warranty is free.
A clone copies what is in your module.
We transfer the data as we read it. If another shop or tool already worked on the module — an unfinished clone, a tune, a delete — that data can come across too. Tell us before you ship.
What "plug-and-play" means.
No dealer programming should be needed when your original data is intact, the donor matches your module (same type, hardware and software family) and the rest of the car works. It isn't a promise that the car will start or run.
Shipping Instructions
These details are also emailed to you the moment your payment clears.
IMPORTANT: send photos of the Body Computer label + connectors and the part number BEFORE shipping so we can verify compatibility. Then ship the module to PO Box 120241, Arlington TX 76012 if you ship USPS — or 1009 Oakwood Ln # 120241, Arlington TX 76012 if you ship UPS or FedEx (UPS and FedEx cannot deliver to a PO Box).
