Can't start my car; key won't turn

[eddiememphis]

Most dealers can build you a new cylinder. You can look up the key code from the VIN if it has never been changed or a good parts guy can build one from reading the key.

I have seen the opposite of your problem. So gunked up the pins stay in place and you can turn the cylinder with any key or flat bit of metal.

Or the tech brings one in that won't turn. Tear it apart and there is the very tiny end of a key broken off in it. Saw one that had a cigarette filter stuffed deep into it. I think that was a Charger owned by a Denver Nugget. That guy lost keys like i've never seen. I sold him six key fobs in one season. He had my direct line.
