i tried with 5 transponders, they where from a batch of 10, the other 5 worked previously. i tried to select eml to, at one point still nothing. car is 2010. should i use another programmer for ews?

one thing. when i read the transponder i don t get any vin or mileage, only key position. on all other keys i programmed on other cars i got vin...

If the car starts with old key without problem,than maybe you should check with bmw inpa for example, what key positions are allowed for programming. Maybe you should choose another position.

Read EWS4 again with AK90 add new key in position 4, save the changes and write the changes in EWS4 with AK90.

Again read EWS4 with the new changes now program new transponder PCF7935AS in position 4, after that read the new key to see if the VIN number and key position it's right

Final step put the EWS unit back into the car start the car and synchronize the remote control.

Try this diagram, use with AK90

PIN 1: VCC
PIN 2: CLK
PIN 3: XCLKS
PIN 4: RESET
PIN 5: BKGD
PIN 6: GND

If the car not start, synch with INPA.

Good luck wink

I think e83 with ews 4.4 uses pcf7936 which should be switched to crypto mode

Normally for EWS4. I use a BDM adapter much easier.
It can also be used with R270+.
