I don't get why people chime in to say they don't have a problem when so many do. I for one think its an arrogant design to say the key fob for a particular car is more important than anything else. I have had as many as 3 cars , 2 trucks and a motorcycle to juggle keys for. I leave the key fobs in a drawer, but you can't start the z without it. I would put an ignition lock and keyed door locks in if I could.
O for a life simple enough to only need to carry 1 car key, 1 house key , 1 garage key and so on and so on .
