Question:

To add key for BMW EWS system, aftermarket or original? I programmed VVDI Chips but car cranked not start.

Here are some choices:

1.VVDI XT27A Chip (set as 7935/ ID33/ ID42)

Reviews:

BMW X3 ews4 make key chip from vvdi xt27 by AK90

Ak90 can only write on xt27a generated as 7935 id33 and id42

2.VVDI XT27A Chip (set as ID41 Nissan)

Review:

Xt27a is fine don't use vw 7935 use the Nissan version. It works every time for me. My service vehicle is a x3 with EWS 3 and I also have an x5 service vehicle.

3.New VVDI XT27B Chip

Review:

I use xt27b. The best for all

4.New VVDI XT15 Chip

5.Original Chip

After few weeks all info from transponder use always pcf 7935

Hope this could help!
