I started up my Explorer the other day for my wife with the remote key in my pocket and then my wife took off with it across town. But I forgot to give her the remote key. I had to call her cell and tell her not to turn it off (or lock the doors) because she probably would not be able to get it started again. But she was able to make all her stops without any trouble (except the part of not being able to turn it off). Is this what is supposed to happen? I somewhat expected the car to power down after not sensing the key anymore?
