mini-security feature

I was thinking of wiring a push-button switch or a toggle in-line between the ignition pushbutton and it's 12v input, tucked away in an inconspicuous spot, or even next to the ignition button, so that the car wouldn't start (even if you had the fob) without the switch being on.


Something like this:
Pilot Automotive - Performance Switch: PL-SW57B

or like this:
Pilot Automotive - Performance Switch: PL-SW25B


Has anyone done anything like this? Any drawbacks to consider?

 

Umm, probably not worth the time and effort if all I wanted this for was to have an antitheft device. But I also want to do this because it's cool, and my wife won't let me install these. (yes, I know, I'm being a bit childish, but it's never too late to have a happy childhood)



I'm planning on buying a replacement trim piece, so I can just swap them out at resale time.

 

OK, let me try this another way, or maybe two other ways. Keep in mind that I'm doing this mostly because I think it looks cool, but having a cool switch on the car that does nothing but light up seems to be crossing the line into completely silly, which is a bit too far for me. You've all convinced me not to try to make this a traditional kill switch, which physically stops power getting to the engine.

1) The ignition button switch seems to be a momentary switch, so that pressing it sends a brief signal to the computer to start the car, and then pressing it while the car is running sends the same signal, which tells the computer to stop the car. I'd be really surprised if it was directly connected to the battery, the way that a conventional car's ignition switch is.

My thought was to attach the stealth switch so that it would interrupt the wire that sends the signal to the computer - if the stealth switch is open, the only thing that's disabled is the ignition button switch, nothing else at all. The stealth switch isn't a momentary switch - it's one push for on, closing the circuit and letting current flow, then the next push for off, opening the circuit (preventing current flow).Getting power to light the stealth switch led becomes a different issue, which I will hopefully figure out. I don't see anywhere to mount this except right next to the ignition switch.

If I'm wrong about the type of switch the ignition button switch is, could someone here tell me, before I go looking all sorts of foolish trying to do this mod, please?

2) The other way to do this is to ask you guys for even more help, along the lines of :" I found this really cool switch from Pilot that has an iris to close which (hopefully) prevents anyone from figuring out it's a switch. Can anyone here come up with a way to use it in the Prius?"
