Programming Procedure

Step 1: Connect the Hardware

Connect the EWS4 Adapter to the VVDI Key Tool Plus using the DB15 cable and Multi Function Adapter, then plug it into the Mini Prog port.

Insert the EWS4 module into the adapter, then connect the external 12V power supply to power up the module.

Step 2: Read EWS4 EPROM Data

On the Key Tool Plus, enter:

Prog → IMMO → BMW → EWS4.X → Adapter.

Then read the EPROM data and save the file locally.

Step 3: Generate the Dealer Key

Go to:

IMMO Programming → Europe → BMW → Select from system → EWS immo System → Prepare dealer key from EPROM dump → Start programming → EWS4

Load the saved EPROM file, select an unused key position, then place the key blank or Super Chip into the induction coil for programming.

Once the write process is completed successfully, the key data is ready.

Step 4: Finish the Key

Cut the mechanical key blade and perform the standard BMW remote synchronization procedure.

Why Use the Xhorse EWS4 Adapter?

Traditional EWS4 programming usually requires manually soldering several wires to the PCB. The Xhorse solderless adapter avoids that entire process, making the job faster, cleaner, and safer for regular workshop use.

For locksmiths handling BMW all-keys-lost service, this setup is one of the most practical solutions currently available.
