Luckily we have keypads for our garage doors and the door into the house from the garage so we don't have to carry keys too often for the house! In fact, we also have a keypad for keyless entry on our SUV... but it is a Lincoln that we bought used from a Chrysler dealership, and they couldn't code it for us when we bought it. All we've had to do is make an appointment to have it done at a Ford/Lincoln dealership, but we bought it in May and haven't made an appointment for that yet either
That is also next on the to-do list! And a membership to CAA!
