I have a 99 accord sedan ex, 88 000 KM on it

looks like the key ignition switch has gone bad....ALREADY...
(never heard of such problem on a car)

so i was wondering if it is easy to switch over to button ignition start....like high end sports cars
doesnt have to be one of those...wireless key things...

i dont mind actually pligging in a key but i just dont want to use the key to start the engine

in another words.... im really scared of this same problem happening again
if u can imagine ur engine shutting off, steering locked, and u cant put ur gear into park since u are in the middle of the road driving 50 miles/hr and ur car is still rolling....
