When you say it didn't start, you mean nothing happened at all? In
other words, the starter wasn't turning over at all?
What do you mean by pushing the key hard? Are you saying that nothing
happened until you did something special to your key?

In case of doing something special to the key, it might be your
ignition key.

Go to www.tegger.com. It has a "no start" condition page. See if you
can describe better as to what your car is/isn't doing. Post your
findings here. With more info, someone here will be able to help you
determine what's going on.
