Today we’re working on a 2004 BMW X5, this is a EWS3 module which already been pulled out of the car. Following we’re gonna show how to program a dealer key with Xhorse VVDI Key Tool Plus + XDNP50 EWS3 Adapter for it.
Step1. Read Immo Data
The first thing we should do is to open this plastic case of module, then connect it to the BMW EWS3 Adapter.
Here we can check the wiring diagram:
Prog >> IMMO >> BMW >> EWS3 >> Adapter
After successfully connecting, read & save the file.
Read >> EEPROM >> Start >> Continue
Save EEPROM file.
Step2. Make Dealer Key
Immo programming >> BMW >> Select from system >> EWS immo system >> Prepare dealer key from EEPROM dump >> Start programming >> EWS3 >> Load EEPROM dump file >> Selected a blank key position
Please put new key into VVDI Key Tool Plus programmer.
Start make key, please wait…
Make dealer key success.
So now this key can be used to start the car, the remote would have to be programmed separately.
* Please notice after programming the key, the EWS module will not recognize the slot as being used until the key is actually used in the car.
