question

So my local automated car wash removed my antenna cover. I have recovered it but unfortunately part of the cover was broken off and not recovered. I have a patch in place and have glued into position using JB Weld Plastic Weld but would ultimately like to replace it. I am have trouble swallowing...

I'm new to the Hyundai community and this is probably a dumb question. But its been in my head since I got my car a couple weeks ago. Is it possible to add the proximity key functionality, even if it isnt practical at all? :)
