Sounds like either the steering lock is on or you need to take the whole friggin thing out.
My friend's 95 MX-3 had that problem...we could hot wire that thing so easily, but the key wouldnt go in instead and the steering lock was still functional.
Good luck man. Never had that problem on my Toyotas
