I have a 94 Civic. Normally, after the key is fully inserted, the lock mechanism must be pushed in a little,before the key will turn. All of a sudden, when I try to start the car, the key will not push the lock in so I can turn it. If I fiddle around with it, I can make it work. Solutions?

If you don't have a better key, or know of a craftsman/locksmith, they may be able to make a key, less the wear, by careful placement in duplicator, if not call one of the discount type auto stores and ask for cost of replacement ignition switch(comes with keys),
May be worth it.
