I was disappointed today to receive my key fob and see it does not have a opening to attach a key ring that would allow me to hang the fob on my key board next to my garage door. So when my car is at home in my garage I would like to leave the fob in the car so I don't have to find a special place to put the fob in the house when I come in from the garage. Also leaving the fob in the car in the garage avoids the car being locked if I am in the garage and decide I want something out of the car or want to vacuum the mats. Any reason not to leave the fob in the car in my locked garage?
