Dear DavidMacK,
MkeMaker was right on all counts on the trunk lock, picking the lock, keying it, inserting new key and turning the cylinder to push release pin, not forcing the pin etc.
Now for the door Locks. Either remove your ignition switch and build a key from it, or get some special hardened drill bits and remove a door cylinder to get a new key made to fit them. It will/should fit your doors as well.
Remember no forcing anything. Slow and steady wins the race.
In this case a couple of breaks/as in break frre oil and rests, and other cases, as in beer may be in order as well.
Tom
