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 Quattroporte M139 / early GranTurismo
- Need a spare Maserati flip key programmed
- Used / donor BCM needs key data set up before install
- No-start immobilizer fault tied to the Body Computer
- Dealer can't or won't do an all-keys-lost flip-key job
Won't fix:
- Newer push-start / smart-key Maserati without separate verification (quoted separately)
- Fiat / Ferrari / Alfa Romeo modules (similar concepts, different layout - verify each)
- Mechanical key-blade or lock faults unrelated to the BCM
- 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.

Maserati Engine ECU Clone
Cranks but won't fire after a used Maserati ECU swap? The engine ECU is married to the Body Computer immobilizer, so a donor from another car never starts yours. Mail in your original plus a matching donor and we clone the identity, immobilizer, and VIN data across on the bench — plug and play.
Maserati BCM / Body Computer Clone
No-start immobilizer fault or a used Body Computer that won't accept your keys? The Maserati BCM holds the immobilizer, key authorization, and config, so a donor from another car locks you out. Mail in your original plus a matching donor and we clone the Body Computer data across on the bench.
Maserati CFC Gearbox TCU Clone
Gearbox won't engage, stuck in limp mode, or a dead DuoSelect / Cambiocorsa TCU? The electro-actuated gearbox controller carries its own adaptation and config. Mail in your original plus a matching donor and we clone the CFC data across on the bench so a replacement drops in.
