Replacing new iPhones as keys

Moderator comment - thread renamed for clarity from "New iphone"

Hi

My wife and I just got new iPhones.

what’s the easiest way to sort out the new key using the phone

Shall I just delete everything in the car and set everything again?

We both got new iPhones.
Added the new ones first, then deleted the old ones (just in case!).
Worked fine
