It's most likely the ignition key lock cylinder. Best to have it replaced by your local Buick Dealer. With GMs VATS security system there were 15 different key chip possibilities. You'll have to get the correct one for the system to work after the lock cylinder is replaced. Your Buick Dealer can determine this by checking your old key. HTH. -Jim
