I was looking to replace all the locks (both doors and trunk) and the ignition on my 1968 Coupe DeVille and wondered what you recommended for a company to purchase these products from. My current keys and locks don't seem to match. One key opens the trunk. One key opens the driver door and starts the car. The third key opens both doors but doesn't start the car. :banghead2

Advise?

Interesting. The way it SHOULD work, is one key for ignition, and doors, the other key for the glovebox and trunk. Sounds like the trunk key is right, and on the key that starts the car, try pushing in with a little bit of force while turning on the passenger side door. The locks are a bit odd on these cars. The one that opens both doors but doesnt start the car? Compare it with the one that does start the car.
