With the above in mind, it seems like most of us will want to make a conscious choice on whether or not to get smart-key-driven vehicles based on those two big things — cost and convenience.
If money isn't an issue, you can buy all of the smart keys you want, and when you're locked out, you could call a locksmith, or get towed to the dealership. But if you want practicality that allows you to do more with the vehicle yourself, or you don't feel like reading the manual, a traditional key vehicle might be the way to go. Where a lot of us get lost is where we fall into the "newer is always better" mentality. Smart keys aren't the only auto accessories that this applies to — for instance, just look at the change in cost in headlight lamps — from about $10 for last decade’s vehicles, to around $100 for the modern and mandatory headlights of today's late-model cars.
In other words, smart keys are fine if you want them and you're ready to invest the money, the time and effort. Otherwise, you can't make car companies change their designs, but you can get a new-to-you vehicle that still features the traditional "car operating systems" that some of us still love.
