Just to clarify, you found your old keys and you just want to replace the key cylinder at this point so that you don't need to get new keys and program them to the new switch? If this is the case, it does appear you replace just the cylinder.
However, you cannot remove the chip and swap that over. You would need to keep the old keys with the old switch or new keys with the new switch. They do not interchange.
