I was preparing to take my 3 year old grandson home with the help of my husband who was strapping him into his car seat while I was grabbing my purse. In my rush I forgot to get my key. Unbeknownst to me, the car started because my husband had his key in his pocket while dealing with the car seat and I was in the driver seat starting the car. I drive off and drop my grandson off at his parents. Upon leaving the parents house I realize that I cant start the car to get myself home! My husband had to drive 45 minutes to bring me a key. It seems that there should be some sort of indicator (chime) that would alert the driver was out of range of the key.
