Another predicament I have found myself in. I have never had door keys to my car. The driver's door lock is broken in such a way that any key will lock/unlock it and that originally made me think it was a one-key car. However that is starting to fail such that NO key works on the driver's side without alot of wiggling. And of course, I don't have a key for the passenger's side! So lately I have taken to never locking the car lest I get locked out for good. A couple questions: Can keys be make for the existing locks or will I need all new locks? How easy is it to replace the locks if I have to replace one or both? Thanks for any advice. -Sean
