FEM/BDC key programming over OBDII (BMW F series) - all keys lost and spare key

Key programming on BMW F series vehicles with a FEM/BDC module, carried out over OBDII. It applies to BDC units with software version below 85 and to FEM/BDC units (above 85) that have already been prepared/unlocked. It covers both the all keys lost case and adding a spare key.

Procedure

1. Connect the AVDI to the vehicle: the ignition comes on automatically, that is how Abrites Diagnostics for BMW Online works. Check that the external power supply is connected to the battery.
2. ALL KEYS LOST CASE - Go into the "Keys" menu.
3. Select "ISN codes" to read the ISN from the DME/DDE: it is the data you cannot do without to carry on with all keys lost programming. The operation may require programming of the engine control unit.
4. Copy the extracted ISN into a notepad on the computer, then go into "EWS Manager". Here you will find the entries: "Program keys", "Clear mileage", "Save EWS DATA", "Restore EWS DATA", "Erase Key", "Virginize".
5. Before writing anything, use "Save EWS DATA" to save a backup of the EWS data to a file.
6. Choose "Program key", enter the ISN from the DME/DDE and carry on.
7. Choose a free (empty) position to program the new key into.
8. Put the new virgin key in the PROTAG and wait for it to be written.
9. Once the write is complete, hold the key on the slot marked with the key symbol and two arrows on the steering column (BMW calls it the "Ring Aerial"). The key is programmed and starts the vehicle.
10. SPARE KEY CASE (working key available) - Go into "EWS Manager" and choose "Program key".
11. Select the working key option ("working key"): the ISN is far easier to get from the key than from the DME/DDE.
12. Put the working key in the PROTAG to obtain the ISN.
13. Choose the position to program the new key into and put the new key on the PROTAG.
14. Once the write is done, hold the key against the "Ring Aerial" on the column: the key is ready to start the car.
