Yeah, you missed the point, entirely. The described circumstances are not supposed to be rationalized into some episode of Punk'd or anything. I'm talking about honest to goodness magical voices from heaven that possess the speaker system that is really just part of the fire alarm and doesn't have a microphone on it anywhere. I'm talking about the real odds that a Honda Accord key will fit and activate a Maserati ignition with no Ashton Kutchers hiding behind the bushes. That you will generate an address containing 100 BTC is just as likely.
If a Maserati key system cannot physically accept a Honda Accord key then its more likely you will eventually generate a Bitcoin address containing 100 BTC. This is because that physical key has no ability to ever fit into a Maserati ignition
assuming physical incompatibilities.
One of those things is impossible but the other is possible but highly unlikely.
I am not aware of any way a metal key can randomly morph into another physical shape with no help and assuming we don't jam it in there as hard as possible.
Of course if the keys are similar it may become possible that a manufacturing defect could randomly make a key that fit both ignitions. This all really depends upon how close these two chunks of metal are in their manufactured state.
