Mercedes-Benz BGA Key Programming: The Definitive Guide

Mercedes-Benz vehicles are among the most lucrative jobs for automotive locksmiths. This guide covers the complete BGA key programming process using Xhorse tools.

Mercedes Key Types

• BE Key (BGA Chrome): W204, W207, W212, W164, W166, W221. Requires BGA password calculation.
• FBS3 keys: W205, W213, W222. More secure, specialized tools required.
• FBS4 keys: 2019+ models. Latest generation with limited tool support.

Tools Required

• Xhorse VVDI MB Tool or Key Tool Plus Pad
• Xhorse BE Key Pro (XNBZ01EN) — the key blank with BGA chip
• MB BGA Token — 1 token per key calculation
• ELV Emulator — if the Electronic Steering Lock is faulty

Step-by-Step BGA Key Programming

1. Connect via OBD: Read EIS (Electronic Ignition Switch) data automatically.
2. Calculate password: Uses one MB BGA token. Takes 1-10 minutes.
3. Prepare new BE key: Write key data to the BGA chip.
4. Write key to EIS: Program the new key into an available key position (up to 8).
5. Cut the emergency blade and test all functions.

Cost-Saving Tips

The One Year Unlimited MB Token Package ($399/year) is the most cost-effective option for 15+ Mercedes keys per year.
