? About Remote Start - 2002 Mustang Coupe 3.8L Automatic

Hello,

Thanks for any help you can provide. I just bought a 2002 Coupe 3.8L
Automatic. The guy who sold it to me had a remote start installed, it
seems to work just fine. But he could only give me one key, he said
the other one was used for the remote start. I asked him if I could
unplug it and he said he had no idea where it was in the car. So now I
would like to make some duplicate PATS keys but I only have one key so
I would need to go to the dealer and pay. Is it possible the key is
inserted into the remote start module? The more I think about it, they
can't work that way because an extra key would be in the car for the
thief. Was the chip probably removed from the key and placed in the
steering column? And if this was the case, Could I get a blank cut in
the shape of my key, and would it work to start the car because the
chip it needs is already in the steering column? Thanks for your
thoughts and any help you can provide.
