1968 Key questions?

[classicsguy]

How were 1968 Mustangs equipped with the different keys for ignition door and trunk?

Are the doors and trunk same key with ignition being different?

Looking for the correct way they came from Ford

Door and ignition are the same, trunk and glove box lock (if present) are the same.

Square double sided key for ignition/doors.
Round double sided key for trunk/glove box.

Here is some information regarding those key codes.
