Make sure your steering wheel isn't locked. Sometimes a key won't turn until you jiggle the wheel while trying to turn the key.

You may want to try to slightly push / pull your vehicle to take weight / tension off the transmission, which in turn will allow you to turn the steering wheel enough to see if the ignition switch can be turned.

If your steering wheel is locked, turn it a bit away from the locked position. Key should turn now.

Otherwise, you may need to replace the ignition or you have a bad copy of a key.

I have had this happen on my 98 Voyager. Just have a new key cut. This new key will sometimes cure the problem. The older keys get worn out and won't unlock the ignition. Try this before a much more expensive and time consuming change of the ignition.
