hello I have a problem with my Mercedes w210 (e class, 1999)
in last 2 days I can't unlock it with my remote key but I can lock it and
open the trunk with it but, like I said it doesn't work when I try to unlock it.
I can unlock the car from the central console when I start it. I changed the
batteries in the remote keys but nothing changed.

and I don't know if this has to do something about it but, at the same time
my two front windows doesn't work...

So if somebody knows what the problem is let me know

greetings
