Both Xhorse VVDI MLB Tool and Autel APB300 enable add-key on VW/Audi/Porsche/Bentley/Lamborghini MQB48 and MLB platforms by reading data from a working original key (open the key, no dashboard disassembly needed in most cases). Which is better?
Here is the clue.
Process is similar: Read original key data → Calculate/generate dealer key data → Program/learn new key.
Both support generating/programming compatible keys (Xhorse has strong ecosystem for its keys; Autel works with IKEY and some aftermarket with pay-per-use).

- Xhorse MLB Tool: Praised for no-dash disassembly, stability, and local control. Many tutorial videos demonstrate successful MQB48 adds (e.g., Audi Q2L). Users note it’s a “premium choice” for data integrity and complex jobs. Some early adapter issues (voltage/power) led to software fixes.
- Autel APB300: Newer (launched ~early 2026). Positive for quick key reads and integration with Autel tablets. Good for standard adds, but Facebook/group feedback includes pay-per-use problems for non-Autel keys.
- General Xhorse vs Autel: Locksmiths often say both are solid but excel in different areas — Xhorse frequently preferred for deeper VAG/MQB work.
Recommendation
- Choose Xhorse VVDI MLB Tool if you do a lot of these jobs, want proven reliability/stability, or already have Xhorse hardware. It’s the more battle-tested option for MQB48/MLB add-key.
- Choose Autel APB300 if you already own a compatible Autel tablet (IM508/IM608) and want a simple plug-in solution without buying another specialized device.
- Other options: KEYDIY KD-MP and KD-X4 tools are sometimes mentioned as alternatives with good integration.
Advice:
Check the latest software updates for either tool, use a stable PC/power setup for Xhorse, and verify coverage for your specific vehicle/year. Real-world success depends on the exact model, key type, and technician experience.
