After searching the web cloning the key dosn't seam to be an option

I have one original working key + another 2005 mk2 S40 for spares with 2 working key/remotes

Can i use the original key to program the others from the S40 or swap parts from the S40 to V50 to use the S40 keys in the V50?

What parts would i need to swap from the S40 to get them to work in the v50?

It would be nice to have the remote locking working as well as the immobilize

Any advise

Thanks
