I would like to know if it is possible to have one key fob with multiple buttons, programmed for multiple vehicles? Instead of carrying fobs for each vehicle. Maybe even a button to open the entry door to my house?

We're going to assume that you are also carrying the keys to multiple vehicles, right?
