The problem is not the ignition switch, but the ignition lock cylinder.
First thing I would do is look at your key..is it worn down a good bit?
Try a new key (like your spare)..DO NOT have another key cut to match the worn one (copy a key)..all you are doing is copying the worn key.
If that does not work then you will have to replace the lock cylinder...the new lock cylinder will have to be "coded" (new tumblers installed)..some dealers or any locksmith can do this for you.
