VAG Key Device V2 (Passat) – Advanced Key Learning & Pre‑Coding Tool for Immo III / Immo IV Vehicles

The VAG Key Device V2 is a professional, plug‑and‑play solution designed for fast, reliable key programming on Volkswagen‑Audi Group vehicles equipped with Immo III, Immo IV, and Bosch EDC16/EDC17/MED9/MED17 engine control units (ECUs). Built for automotive locksmiths, diagnostic technicians, and ECU specialists, this all‑in‑one kit simplifies the entire key‑learning process, including pre‑coding new keys, retrieving PIN/CS data, and adapting up to four keys to the vehicle.

This upgraded V2 edition supports all VW, SEAT, and Škoda models up to ~2015 using Bosch ECUs. (Note: Audi models and MQB/MLB platforms are not supported.)

Complete Professional Kit

The VAG Key Device V2 includes everything needed for a smooth key‑learning procedure:

OBDII dongle
ABS cable (for accessing the internal powertrain CAN‑Bus)
Key‑learning device with integrated transponder programmer

This complete setup ensures accurate communication with the immobilizer system, even on models where direct access to the CAN wires is required.

Key Learning & Pre‑Coding Made Easy

The device allows technicians to program 1 to 4 keys by setting the DIP switch configuration before starting the procedure. Once configured, the tool automatically:

1. Reads PIN & Component Security (CS)

A fast‑blinking GREEN LED indicates live reading of immobilizer data from the ECU.

2. Pre‑codes New Transponders

Whether the vehicle uses mechanical ignition or electronic ignition (Passat B6/CC/B7), the device prepares the blank key and writes the necessary CS bytes.

3. Adapts Keys Directly to the Immobilizer

A GREEN/RED blinking LED signals the adaptation phase.
When completed, the device emits two fast beeps and blinks slowly GREEN.

For electronic ignition systems, the tool automatically handles the mandatory 5‑minute authorization delay before key learning can begin.

System Warnings & Error Indicators

In case of an error, the device provides a clear sound alert:

1 short beep: No ECU communication
2 short beeps: ECU PIN/CS mismatch
3 short beeps: Transponder not detected or locked
4 short beeps: Immobilizer rejected adaptation
5 short beeps: No communication with immobilizer

This ensures fast troubleshooting and safe operation.
