Keep the hardware. Change the key.
You may like the hardware on your front door and still have no clear picture of who holds a spare. When a cylinder is suitable and in good condition, rekeying can change the key that operates it. That is a different decision from replacing a damaged handle or fixing a door that will not close properly.
Look at the openings you use, rather than only the key ring. The front door and the door from the garage may use different cylinders. One key for several doors depends on compatible hardware; it is not a promise that every existing lock can be matched. The home-lock page explains what to keep in that review.
