The 1970s cars also used the round-and-square-key combination, might investigate there, too....

Many years back, O'reilly offered a matched set of door/ignition locks for the 80. Doesn't appear to be available now though.......
If the door lock set does have the square keys, it wouldn't be that difficult to take them and an ignition lock to a locksmith, and have them keyed alike.
Honestly, if I was to have a different key for the doors and ignition, I'd rather have the round keys for the doors. It can be a royal PITA to have 2 square head keys for the same vehicle, 1 for doors, and the other for ignition. Been there, done that. Had a 79 t-bird with lighted door locks, and some how the ex wife managed to break 3 different ignition locks in that car.

I wanted to add to the discussion.
I tried these out for my 1985 from Ebay since they were cheap and if they did not work it would not be an expensive experiment. I planned on rekeying the locks to my ignition. I discovered that the original square ignition key, while the orientation is correct, is too wide to fit into the Ebay cylinder. I do not want to rekey my ignition to their supplied keys because they are super thin.
Elsewhere I have been told that these Standard Motor Products may have a wider keyway,

Another thread on the same subject:

Worked great for me. Unfortunately, I think some of those recommended products have been revamped and are no longer applicable for a single key conversion.
