Although BMW EWS is a very easy job can be done by cheap AK90 at $30, it is just nice to know Autel MaxiIM can do EWS3 if happens to have it in hand.
Which Autel can do?
*XP400 cannot read/write EWS3. Require XP400Pro.
What adapter to use?
To read EWS needs IMKPA set, that adapter is inside there !!
Ews3 adapter (APB114 EWS3 adapter board) the tool tells you what to connect the wire to
APB114 EWS3 adapter is included in IMKPA Accessories (Needs to Buy IMKPA Accessories Separately).
Autel EWS3 Adapter Instruction
just plug in and solder only that wire and read after. 15min whole job.
How to Program BMW EWS3 key with autel im608?

I have the ak90 I just choose to do it this way and it worked out a whole lot easier and faster
FYI: IM608 does EWS4 as well. Doesn’t require EWS4 adapter, direct read and write.
