The design on the left, like the one Michael is showing an original of is definitely what was used in the later Pagodas, also after they changed the ignition key ( which also worked the doors and trunk?) to a plastic end. The earlier Pagodas like the 1963, possibly even up to 250s, I think used the earlier fob like the one on the right in the link and the ignition key did not have a plastic end (and had other keys) or work other locks on the car. The question was about a 1964 230.
