gpg --card-edit
passwd
then asked for the PIN, default pin "123456" entered
asked for the new pin, new pin entered twice
and then this

"Error changing the PIN: Conditions of use not satisfied"

When I try to change the admin pin something similar, "permission denied". 
What is wrong, why can't I change the pins?
