The link to the problem mentions the Chevy Cobalt Model, but I would be careful that it doesn't happen with friends and family.
Now....Just for Kicks and Giggles, I checked Tina's Key strap / hooks and cards and stuff.
We reduced all this to just her car key. She is going to get a small strap for that, and she can just keep all her other junk separate!
Better to be safe than sorry!
