Simplify your Maserati’s starting system with our professional Immobilizer OFF (Immo Off) ECU programming service for Maserati Quattroporte (2009–2013) and Maserati GranTurismo M145 (2009–2018). This service reprograms your ECU/DME to bypass the immobilizer system, eliminating the need for the transponder “pill” inside the key fob.

This solution is ideal for lost keys, failed or unprogrammable transponders, and immobilizer module failures, providing a reliable plug‑and‑play starting solution while keeping the alarm system fully functional.

Important: This service is for bladed‑key vehicles only and is not compatible with proximity (smart key) systems.
