What is the most expensive KEY FOB replacement in the market? Has anyone had to replace their KEY FOB? If so, what car and how much did it cost? ---

No clue on most expensive, however I just had an extra valet key made for our 2011 Subaru and my favorite locksmith charged $75. Took him a few days to get the right key, but he is much cheaper and more convenient than my Subaru dealer. ---

Replacement key FOB’s are readily available on ebay. ---

I’m curious about the claim (made in reference to my two Ford Fusions) that if I have two keys, I can get a third made and train the car to recognize it easily, but if I have two keys and lose one, the only way to train the car to recognize a new second key is to go to the dealer and spend some enormous sum for some reason. ---

That is the principal reason why it now requires two keys for the car owner to make himself a duplicate. Up to eight programmed keys are allowed per car. ---

I agree with what Mechaniker said… It’d be pretty low security if anyone could just clone a key fob in 10 seconds with one key. But maybe a better solution would be to require the owner to punch in a code on the stereo or something to clone a key if only one key remains. This would eliminate a lot of hassle, and who needs to make another key unless they lose one? And how many people need 3 keys to their car, ‘just in case’? ---

Thanks, Mechaniker. That makes sense.
