There is a transponder in the key that is “mated” to the immobilizer circuit in the car. You can probably have a new key blank cut for your old 451 key fob, then have the car reprogrammed to accept your old key fob. The dealer can do this (yuck) or a locksmith with good skills and the correct equipment can do this in minutes. It’s not always inexpensive, I think I paid $50 for cutting the blank and programming, but it’s far less than the dealer will charge!
Smart key question
So I just bought a sweet new to me 2010 yellow 251(!!!!!!!iiiiii)
I have only one key with it so my question is, do I need the electronics in the key for it to run? Meaning if I have a key cut to work but it doesn't have the chip in it will the car run?
Also, can I transfer the electronics from a key from my old 251 to this one somehow?
Lastly, if no to transferring or using without chip where is my best source for a replacement key?
Thanks for any help
Will this work?
