Yes, I did this when DH bought himslef a new Corvette about 14 years ago. We were sitting in the dealers office finalizing and paying...then I asked about only ONE keyfob??? He says, "yes the extra one is $xx" I said, for $40,000, I think you can give us a free fob..he did.
ETA: I now have a Toyota w/ 2 keys and one fob. I am horrible about locking my keys in the car, my old car had a combination key pad to get in, so I always just locked the key in on purpose..(I know not advisable.) So now I am in the habit, but my new car doesn't have a combination. So I bought one of those magnetic boxes, and since the keys are so expensive from Toyota..I got one from
Walmart cut that will only open the door..so I can still get my keys if I lock them inside, but I can't start the car with the hidden key.
I'm really stupid about locking keys in cars..
