Switch Key

I had a meeting in Anoka today and our new car at work was available.  I signed out a key from the key cabinet and I looked at it a little confused.  This key didn't look like the other car and van and bus keys.  It almost looked like a hybrid car key.  I thought maybe it was one of those keys that you don't actually stick into the ignition but just have somewhere in the passenger area.  But I was pretty sure this Ford Focus wasn't a hybrid so I asked.  "Oh," said a helpful staff person, "Do you want me to show you how to use the key?"  Trying not to feel insulted about being offered a lesson on how to use a key, I smile and say, "Sure."  She presses the round metal knob on the upper corner of the key and PRESTO!  A switch key flies out of the key fob.  It's like a switchblade but a key.  A switch key!  I am fascinated.  Grabbing my coat and my papers, I walk down the hallway popping my key in and out, in and out.  "Check it out!" I swagger, "I got a switch key!" People look at me quizzically (it happens quite often).  I hold up the key fob and press the button.  I falter and fumble.  It takes 3 tries to get the key to pop out when I'm trying to show off.  Serves me right.  The world is changing so quickly.  Even car keys are confusing to me.
