I was curious if anyone knows how to find out what dealership a car my dad bought came from. We tried to get a key cut at the dealer but they said the key data only goes back 10 years so we need to contact the dealer it came from. I thought this was kinda crazy myself. Maybe I should just remove a door lock cylinder and get a locksmith to cut a key for me. It's a 2000 Sable by the way. Can anyone shed any more light on this for me? Thanks in advance!
