Mapman, the computer chip in the key is for security reasons, not to make ignition better. The chip *talks* to the chip in the engine and says "I am trying to start this vehicle legitimately". If someone tries to start the vehicle without using the matching key, the car alarm will go off. I'm sure it won't deter professional car theifs, but it does provide a level of security for amatuers. BTW, I'm driving a 2008 Toyota Avalon....nice car. :)
Also, it cost about $300 for the full service key, but you can have a spare 'valet' key made for around $90. The valet key has no buttons on it, and will not open the glove box.
