I'm pretty cool with the 2015 manual Fit EX, but the push-button start is ridiculous in this car, and in all cars. How bad would it be to replace the button with a keyhole ignition? I realize that the entrie dash basically has to come apart, but is this dream: stupid, expensive, or impossible?

No idea what to tag, but "Smart Entry System
Indicator" is a problematic thing that exists.

 

Very very expensive and a pointless mod. Just buy the trim level that doesn't use push to start if that is what you prefer.

 

I'd venture it's stupid and expensive, but, given enough cash, many things are possible.....am sure it's doable in some way, but, at what cost?

 

you'd need a detailed schematic of both systems to see how they interface with the car . if it doesn't involve the car's computer it might be
doable , but just the few parts you'd need could end up being a little pricey probably
