Hi guys

Mercedes B-Klasse W245EZS with EZS Leopold Kostal
I have read 9s12 inside, generate keys and write to NEC.....
Done this manymany times, but this one I cannot get it to work
I have used 3 different keys, used all Key dumps and no matter what I do, I get this sign on dash:
Key tech in progress please wait
Have left key in ingnition over night, press buttons, insert it 50x, turn OFF/ON 100x ....and nothing

Any solution for my problem?

redump your EIS with the dump u read at the first time.
check if the keys u made had changed status to learned 14ec .
try to virgin the nec in the key before u program it .

I had no idea, how to solve this problem and I left Key in EZS for four days with my C-TEK connected

-first day; key in ignition turned ON, nothing happens , only sign: Key tech in progress please wait
-second day; I open drivers door, all lamps on cluster turns ON and sign on dash: Key tech in progress please wait
-third day; I open drivers door, all lamps on cluster turns ON and no sign on board computer, engine still does not start!
-fourth day; customer takes his car and say "I cannot wait"

And now I don't know what would happen on fifth day?!?!!
