A 2018 Audi A4 has lost all its smart keys. The locksmith is considering taking the job, but the vehicle is 700 km away for a round trip.
Before accepting the job, one question matters most: Is this an Add Key job or an All Keys Lost (AKL) job?
The answer determines whether the Xhorse VVDI MLB Tool is suitable for the job.
1. Identify the Key Programming Situation
The 2018 Audi A4 belongs to the B9 generation and uses the MLB platform. However, vehicle configuration and immobilizer compatibility must be confirmed before programming.
There are two different situations:
-
Add Key: At least one working key is available, and the locksmith needs to add another key.
-
All Keys Lost (AKL): No working key is available.
These situations require different procedures. Do not assume that a tool designed for key adding can also handle AKL.
2. What Can the Xhorse VVDI MLB Tool Do?
The Xhorse VVDI MLB Tool is designed to support MLB key operations for compatible Audi, Volkswagen, Porsche, Bentley, and Lamborghini vehicles.
Its key functions include:
-
Identifying compatible MLB keys.
-
Collecting key data for supported procedures.
-
Calculating data to prepare a dealer key.
-
Working with VVDI2 or VVDI Key Tool Plus for key learning.
The tool can simplify supported MLB key-adding workflows. It also helps locksmiths prepare compatible keys without removing the transponder chip from the original key.
Important: The VVDI MLB Tool does not support All Keys Lost (AKL). It should not be presented as a standalone solution for a 2018 Audi A4 with no working keys.
3. Can the VVDI MLB Tool Be Used for a 2018 Audi A4?
The model appears in published VVDI MLB Tool coverage information, but exact vehicle and immobilizer compatibility must be checked in the latest software.
Before starting, confirm:
-
The vehicle’s VIN and exact configuration.
-
The immobilizer system and supported key type.
-
Whether at least one working original key is available.
-
Whether the selected procedure is supported by the tool.
-
Whether VVDI2 or VVDI Key Tool Plus and the required authorization are available.
For an AKL vehicle, stop and verify an alternative supported solution before accepting the job.
4. Before You Drive 700 km
A long-distance locksmith job requires more than checking the vehicle model in a tool’s coverage list.
Confirm the key status, immobilizer generation, required key type, equipment, authorizations, and supported programming procedure before traveling.
If the customer has a working key and needs an additional key, the VVDI MLB Tool may be a suitable option after compatibility verification.
If all keys are lost, do not rely on the VVDI MLB Tool alone. Confirm an appropriate AKL solution with the relevant tool manufacturer or authorized supplier.
Conclusion
The Xhorse VVDI MLB Tool is a valuable option for compatible MLB key-adding jobs, but it does not support AKL.
Choose the right tool for the right job. Confirm the vehicle coverage and key status before accepting a long-distance Audi programming job.
