So I have the new lock switch installed and have the new set of keys that came with it. would it be possible to clone the new keys to the old key, that is give it the same code as the old key?

Hello,

You can set them up to lock and unlock the doors on your key fob, but to start your vehicle, no. You will have to have the new keys programmed to your vehicle's Power-train Control Module (PCM) at either the Honda dealership or by a locksmith. This is done intentionally so that people can't go around reprogramming their own set of keys and stealing other people's vehicles.

Thanks,
Alex
