“Though if you really are a key-head, you can still extract a traditional metal key from your fob (people are always amazed when I show them this). “

The ‘metal key’ in my fob will only unlock the door.

The metal key in my fob has been essential when the battery in the fob died. I had to unlock the car and insert the key into the ignition. I had to remove the cover of the ignition first. Thankfully, I paid attention when the car dealer showed us four years earlier. lol

Also, these keyless fobs have an insert on the dashboard - usually to the left or right of the steering column - where you can insert the fob and start the car, should the battery on the fob be dead. The metal key will get you in the door, as you mentioned. Holding the dead-battery fob right next to the push button might work as well.
