I lost my GN keys. I got in the door with a coat hanger but have no ignition key. Luckily the car is in my garage! What is the best way to get another key for the ignition. The door locks I can pull out and take to a locksmith. I wasn't sure about the ignition key? I know I should have made some duplicates but just never got it done. The car is a 1987 Buick Grand National. Any help would be appreciated. Thx
