How many keys do you carry with you when you leave your home?

Two. My car key and my house key.

Let's see...

A key to the house, a key to the truck, and a key to the box containing a spare key (In case I lose my keys).

 

  I take all of my keys with me when I leave home.

Four keys and a fob.

Quite a few....three homes' worth.  Plus my car key.  I did remove my key fob and it now lives in a safety case where no one can steal the car using that capturing device I've read about.  I never really used it anyway....I just unlock the door with the key.  I got into the habit of holding my key sticking out of my fist between middle and ring fingers.  The fob just got in the way.  I think I started holding the key like that back in high school after I started driving.

One key for my convertible.  The house has an electric keypad. 

Five. Front door, back door, side door, shed, car.

A sixth if I'm wearing military green - my khaki. This post was edited by Slartibartfast at June 22, 2021 7:37 AM MDT

Usually three. Front door key, and the two keys that open the sliding glazed door at the rear. Besides these I own eight keys: car (x2), window (x2), window restrictor, bicycle lock, shed, and meter box. This post was edited by Reverend Muhammadovsky at June 22, 2021 7:37 AM MDT
