2009 Mitsu Eclipse, Ignition Key will not turn.

What is your question?

Can put key in ignition. (Have tried both keys). Steering wheel is not locked / will not lock. Tried a small bit WD40 now the key will occasionally turn. Has no issues starting as long as you can get the key to physically turn. Called dealer who didn't seem to think changing the ignition and reprogramming new keys were the issue. They suggested the shift interlock cable. But im not sure about that stopping the key from turning. Anyone have this happen or have suggestions to look into before we have to end up taking it to a dealer to trouble shoot. Thank you

What makes this problem better or worse?

Cant get worse. A squirt of WD40 in the ignition slightly helped but still takes several minuets to possibly start

How long has your 2009 Mitsubishi Eclipse had this problem?

Apparently several wks. Daughter never said it was having issues until it stopped working all together.
