I lock mine in my grandmas garage....trust no one!I just put my 2014 Challenger and 2017 Grand Cherokee key fobs in a metal cookie tin in my kitchen, not far from the inside garage door. Never had a problem. In fact, you can carry the whole tin up to the car and grab the door handle and nothing happehs. Take the lid off the tin and everything works. Also, FWIW I don't lock either vehicle while in my garage.
