Vehicle door locks. The key from my 2016 Chevy will open my 2021 Chevy. It does not seem safe when you assume locking your doors would prevent someone from gaining access to your vehicle. How often do you go shopping, put your purchases in the vehicle and shop some more not knowing that someone can just unlock the doors and steal your valuables or wait in the backseat for you to return and harm you. What are the odds that I have a key from an older vehicle that unlocks my new truck doors and also how many other keys are out there that will do the same thing. At the very least GM should at least warn a buyer that just because you lock your doors that doesn't really mean anything. I am sure alot of people are not aware of this lack of safety. We have safety labels on cigarettes, liquor, guns drugs and so many other things but nothing about locking your car doors doesn't mean they are actually locked. I contacted the dealership where I bought it and they claimed they were not even aware of that until they checked further. Changing the locks will not help so it seems like there should be some option. Insurance companies won't want to pay for any theft.

I discovered that the key to my 2016 chevy van unlocks the doors to my 2021 chevy silverado. I feel totally unsafe now when I leave anything of value locked in my pick-up. With auto thefts and break-ins at an all time high how can anyone ever feel safe locking valuables up in their vehicle.The Chevy dealership where I bought it first didn't believe me but later checked with Chevy and found out that Gm ran out of key codes so they started to reuse them. People in the business of stealing cars or stealing the contents probably can wander thru shopping malls or parking lots get in and out of cars without the owner aware of it. What are the odds that I would have a key that opens two different vehicles and how many other keys like that are out there?
