The most sensible and economic way, IMO, is to order a new vin-matched ignition tumbler from a dealer. It will come with one new key for around $100 (depending on the dealer). If someone knows of an on-line source that is cheaper, I'm interested.
Anyway, that will give you a key that fits the doors, and you can always have them send a second key for a little more $$.
Then, call a locksmith, have the ignition picked. Once it is turned to position II, you stick two pins (paperclips, allen-wrenches, correct tool, etc.) into the two holes and the cylinder with hardened tamper-resistant ring pop out so that you can simply insert the new ones. You'll have maybe $150 into it, but you need the door key anyway, and you'll need an ignition tumbler anyway.
If you choose to grind it out, it's been done, you need to grind the black retaining ring off so that you can get the tumbler out. You run a substantial risk of slipping and damaging a $$ dash, plus you'll need the rataining ring and have a mess to clean up.
Do you already have a door key that works?
