Just stating the obvious that not buying one of these thing that we never seemed to need until they told us we needed it

I never thought I needed one until my wife lost her car keys, and the Fiat dealer charged $1,200 for a replacement.

And it's not even the electronics that makes them so expensive. Modern car keys aren't like the 1970's where it's just a piece of metal with the edges shaved off. Those little key cutting kiosks at Home Depot can't cope with today's complex engraving.
