  • Do I need to swap all parts or just EWS?
  • Would I have to add the keys using toaf/T4 to get the remote locking to work.
  • Would it need any other programming?
Thanks
It would work, but it's a bodge and other items such as airbags might not work as expected, if it came from a saloon or tourer (delete as appropriate) door locks will be affected and definitely airbags.

As an alternative you could buy a key from HERE and have a transponder programmed to suit your original EWS.

You can then use TOAF to code a key remote, job done and no messing around with configuration mismatches.

That is the way to do it
