Killing off nannies - here we go!

[Midnight Drifter]

Alright folks, it's time to start digging into my Yaris and customizing it a bitbut a few things are getting in the way, I believe.

First off, the ignition system. I'm pretty sure that my car has a chip in the key, because the hardware store key I had made as a 'spare' will crank the engine, but the fuel will never get delivered. This interferes with my plans of doing a self-remote-start. I'm guessing that without a key signal, the ECU won't feed the engine fuel even if the remote start mechanism is telling the car to start. How do I go about bypassing the feature?

Next, airbags. I never did like airbags, especially after an unintended deployment in a previous car (it literally just popped as I was driving down the road) me a fractured and 'bag rashed' arm. Furthermore, air bags are getting in the way of a few mods I plan on making soon. Like the seats. Those have airbags. The pillars. I'd at least like to debag the driver pillar to install a gauge pod without worrying about a bag popping and throwing a 2-pound piece of plastic in my face (i.e. the pod with gauges on it) if I ever end up rolling the car. The seats also have bags; I don't particularly fancy the shape, look or feel of the stock Yaris seats so out they go, and in come some Brides. But then the problem is the seats also have airbags. So that will result in 2 unplugged wires. Finally, the steering wheel. There's a leather-trimmed 3-spoke Nardi that is just calling my name, and guess what? It doesn't have an airbag, either. Preferably, I'd rather debag the entire car. I view them as a safety HAZARD as opposed to a safety FEATURE, just from the scare of unintended deployment. So that's gonna trigger warning lights. No sweat, I can just pull the bulbs. But will that throw any trouble codes? (CEL) If not, I needn't worry - but it's always safe to ask.

Let's leave judgement of one's safety out of this topic and follow the mindset that in the State of New Jersey, there is no laws against the removal of vehicle airbags. All input is appreciated - thanks!
