Programming All Keys Lost (AKL) on late-model 2022–2025 Fiat Ducato vans equipped with Hitag AES ID4A transponders has become one of the biggest headaches in modern automotive locksmithing. Standard OBD tools—including Autel MaxiIM IM608 and Xhorse VVDI—currently fail or cannot complete remote pre-coding without factory dealer servers.
In this complete masterclass, we break down the definitive hybrid workflow using the OBDSTAR X300 Classic G3 + MP001 Programmer (with C4-09 adapter) paired with Abrites AVDI to achieve 100% transponder authorization and fully functional remote locking.
The Standalone Problem:
While OBDSTAR G3 can read the BCM Flash and EEPROM on the bench and extract the vehicle PIN code, relying purely on aftermarket standalone key generation leaves the remote control totally non-functional—starting the engine, but locking out keyless entry.
The God-Mode Solution:
BCM Bench Extraction: Pull the Delphi/Marelli BCM and wire up with OBDSTAR G3, MP001, and C4-09 bench harness.
Dump Extraction: Perform a full read of EEPROM and Flash to extract security data and calculate the direct PIN code.
Pre-Coding Transfer: Export the raw BCM dump into Abrites AVDI (or Zed-Full) to correctly write dealer transponder logic and remote sync data to the ID4A transponder.
Final Sync & Learn: Reconnect data lines via the right-hand CAN bus harness to finalize key registration, resulting in immediate engine start and fully restored OEM remote lock/unlock functionality.
