Okay, so I have an 03 svt..today i drove home from college to go to work (only a 30 min drive) everything was fine. I pulled in my driveway switch to my f150 work truck and went to work. When I came back a few hours later I went to hop in the svt and drive back. I put the key in the ignition- key went in as usual, made the dinging noise it makes when the door is open, but then i went to turn it over and it wouldn't budge. I figured i just needed to do the wiggle the steering wheel trick, and still it would not turn. I tried resetting the ecu via removing negative battery cable....still no luck. I figure it is not the chip thing in the key because it would still turn but not start. So I figure my problem is the tumblers?? Anyone have any ideas?? Trust me it's not the steering wheel, it's locked with very limited wiggle room and i tried for about 20 minutes. Any suggestion??
