oh, right...
When I returned to my car tonight with groceries (on the way home from work), my car didn't respond to the key fob. No light -- presumably a dead fob battery, with no warning signs beforehand. (I've never had this happen before.) As I was calling Dani to ask him to bring the spare from home, it suddenly dawned on me that I didn't need to. Oh yes, that's what that projecting metal piece is for -- it's not just an ignition key! Right...
I spent way longer owning cars with plain old keys than owning ones with fobs, but I guess the memories of How Things Used To Be fade quickly. Except when talking to young'uns about how we did things in "our day", of course. :-)
I wonder if replacing the battery in one of these fobs is relatively painless. (It appears I can't do it myself, or, at least, there's no obvious way to open the case.) I know that if you lose one of these a replacement costs something like $150 (!), but I hope repair is cheaper. If it's not, I won't bother -- if the second one also dies while I still own the car I'll just use it the old-fashioned way.
What do Prius owners do, I wonder?

Ford like to set things up with a sliding mechanism so that you can only change the battery when the key is off of the keyring. Other manufacturers have a hidden slot or hole that pushes a latch. You might see if it's mentioned in the manual. It's usually considered a user-serviceable part.
