Ok so I bought my car this past december and we had an unusually bad winter this year. I found myself starting my car to let it warm up enough to even scrape the windows. That being said I have never owned a smart key vehicle before but on my old explorer I would just start it with one key and use my other key to lock it and go inside and finish getting ready for work. Now this car wont let me lock one key in the car with the other WTF. What process do other people use to let their cars warm up?
