There is something really really wrong with the pricing structure of 2-300 for replacment keys, when smart chips are cheap enough to put into credit cards (and secure enough to protect bank accounts).

There is a huge increase in points of failure (and these components DO fail) in these 'convenience' features along with the fact that many cars don't give you a mechanical over-ride to these wiz-bang systems. The current systems are designed to be a cash cow for dealerships, and to help lock out independent mechanics.

There is another issue too. The argument that 'there are plenty of configuration options'. Typically this is sales BS because there is little practical benefit to many of the 'choices', it just inflates the numbers to make the system sound sophisticated. A good system, that is a well designed system, should have legitimate need for only a limited number of configurations. A dictionary full of options is your first indication that this product was not thought out, so they threw everything on the wall
