Sorry I'm not closer to you. I have all my lock tools in my toolbox :-P

To get the key out of the lock, take a pin (a big one if you can find one) and heat the tip at the stove. You want to remove the temper from the steel so you can use pliers to make a TINY L-shaped hook on the pointy end.

Once you've made your bend, heat the pin up again and douse it in water to re-set the temper. This should make it strong enough so it won't bend when you're using it.

Once the lock is out, take it and the key stub to a place where you can get a key made. Having the lock available to test the new key(s) will speed things up a lot. Also, if the cylinder is completely out of the lock, the keymaker can actually see if all the pins are lining up with the new key.

If nothing seems to work, don't force, it, just call a locksmith. He'll be able to turn the lock and remove the broken key, as well as make you a new set of keys.

Something to think about: the broken key may not be the correct one for your ignition. If not, no amount of fiddling is going to get it to turn.

Good luck!
