This is a half hash (old esl type) that hash I provided should work on your esl, if not then use this hash A46AE1500F0D4A0D

Guys,
Last week I made a new key for my W211.
Key number 1 &2 are used, but I do not have key 2 anymore...
So I did write key file 2 to a new key and tried in the car but did not succeed. The display keeps telling me "Teach in new key please wait" for 10 minutes or so.

Then I tried with key file 3 and that worked immediately.

Any one knows why the key file 2 did not work?
Is there any way to make it work in position 2?

Don't get me wrong, I'm happy with my new BE key in position 3 but like to understand why position 2 did not work.

1.read actual hashs from ezs
2. calc key dump
3. write key 2
4. activate key
5. should work

Hi Ficho,

That is what I did...
1. Read EIS with CGDI MB
2. upload & compute password
3. Save file
4. Upload & Generate key files
5. Write BE key with key file 2...

The display shows for a long time " Teach in key please wait".
I removed the key after 10-15 minutes waiting and used key position 3 which worked immediately.

Any step I missed?

I'm having similar problem as you~~

is it CGMB not read and calculate hash correctly ?

Can You Activate the key with CGDI to be in state 14EC or 15EB

You may try this:
1. read EIS, paste the known key password, disable key slot2
2. get enable password and enable key slot2
3. insert working key(3) turn to pos2 ensure it is working
4. read EIS, you will find the 'Special key' has changed.
5. paste the known key password then save EIS data file
6. (you can repeat from 1~6 two or three times)
7. use the new EIS data file to generate key files
8. write new key2 and try

hope this help.
If not, that mean key hash between EIS and ECU are mismatch and cannot sync,
then you will need to read ECU key hash, wipe EIS, load EIS file, paste the ECU key hash then write EIS data...
