The problem is probably something completely different, and easy to deal 
with.

Take a look at this photo:

This is an ignition switch with the switch removed.   Note that the face of 
the tumbler is flush with the chrome surround.

Now, check this one out:

Same switch, with the key installed.   Note that the tumbler has moved 
inwards about 1/16th of an inch.

In order to turn, this tumbler must first move inwards, which normally 
happens when you first insert the key.   But here's the catch.   When you remove 
your key, the tumbler is supposed to pop out flush again, but sometimes it 
sticks.   Then, the NEXT time you put your key in, it bottoms out, but you 
can't turn it.   Don't ask me why.

The short-term solution is to use a paper clip with a tiny hook on the end 
of it, slide it into the key hole, rotate it so that it catches on the 
inside, and then pop the tumbler out flush again.   Then you can insert, and use 
your key normally.

As for how you get the thing to stop sticking?   I'd ask a locksmith's 
advice there.

And if your switch really is terminal, and the problem is more profound 
than this, your only solution is probably to replace it.   I've got complete 
assemblies in stock, for substantially less than what the vendors, meaning 
that they are only expensive instead of ridiculously expensive!
