I just picked up a new key and programmed it for my Mustang.
Now I wonder... How unique are the keys? And are the keys 'specific'?
Someone once told me GM at some point only had like 50 or 60 different keys. I'd believe it now. When my Pontiac had a damaged door lock, I went to the junkyard, and within 20 vehicles, I found one with a matching key to pull the lock assembly from.
So... if it were possible to have two Fords, and two matching keys... Could the same transponder key work in two vehicles? Or are there codes that go between the vehicle and the key that make the key/vehicle combination unique?
And the same for the remote. If I happen to have two vehicles that share a similar remote, could I program one remote for both vehicles? To keep from having to carry a pouch for my keychain!
I suppose if I put the same aftermarket remote start in two vehicles, it would depend on the brand and model of the remote start, but with stock Detroit keys and fobs, what are the potentials here?
