So I had to buy a car recently for a relative (long story). I ended up with a 2006 Saturn Ion. After some research (before buying) it has some decent components... 2.2 EcoTec, 4-speed trans that was used in V6 models so its beefier than the years before 06.
But there was an issue... The key didn't unlock the trunk or either doors. It worked the ignition fine. So the only way into the car was the key fob. My first task for the car was getting the GM ignition recall done for safety reasons. The other open recall was for the assisted power-steering so that was replaced at the same time.
So heres the neat/not neat part. With the ignition recall you are given two brand new keys cut to the code of the VIN. So essentially new keys like the car was brand new. Those new sharp cut keys work all the door and trunk locks.
All this to say... It appears if you never use your key to unlock the doors its possible the ignition and key will wear together, but the door locks will not wear the same. I never saw this as a problem until testing all the things you would on a used car. I wonder how many people out there don't realize that if their key fob died their key wouldn't let them in the car??
