but to work or virginise EWS module, EWS editor works better for me;

for CAS system, I find that the BMW multi tool works great (it is a little pricy and works better than ak300)”


Here is a few questions and answers frequently asked when it comes to bmw key making. Hopefully, it’s helpful.


Q: So which one is better for EWS? AK90 or EWS EDITOR?

A: I bet Ak90 key programmer works fine without any problem.


Q: Where do you get blank keys? or using used keys just replacing transponder?

A: If you go into key then get all you can
AK90, AK300 you have eldb Xprog with latest authorization
also CAS reader like rofar to make key dump manually and a lot of reading


Q: Which tool can make BMW E6x comfort access key?

A: BMW Multi tool, but the main problem would be to get the unwritten key. Used many times via OBD programming or from eep dump. Good quality tool. Blank keys always available via Chinese markets.


Q: What to use for reading ISN from dde/dme?

A: EWS editor is the best. I have been using EWS editor for 2 years for EWS 3 and 4 key making and ISN change. It is faultless.

I use my FVDI commander to read the isn from dde/dme, i write the code in ews ( password) write back to ews and after sync ews to dde/dme using fvdi and voila job done. car start with different ews or dde/dme.
