The door locks are keyed the same as the ignition. So if you can have them keyed to match the ignition as it is a pain to take the tumbler out of the steering column. Not to bad though if you have to. Just need to take the wheel off and tear it down some to get it out. Service or Hanes maual comes in handy for stuff like that.
Good luck
Lock smith may be able to grind you a key for the tumblers you have also.
