Buying a car without keys

Take the passenger side door lock out and take it to the locksmith. The passenger side lock won't be worn out as bad as the drivers side. If you can take the back seat out and crawl into the trunk with a 1/2" socket to remove the trunk latch mechanism, you can then remove the lock from the trunk lid and take it too. The trunk lock may be the same as the glovebox lock if it has a locking glovebox.
