Door lock question 1950's

[barnstuf]

I have a FoMoCo two lock cylinders set, both lock cylinders use the same key. I believe these fit around 1953 to 1958. One lock cylinder is positively for a door, and my question is what does the other cylinder lock fit. Is it ignition, glove box or trunk. in other words what lock cylinder would use same key as a door lock. Upon identifying this combo they will be for sale. The Ford parts number on the box is CPA-7022050-A and the box printing says "cylinder and key set".

Doors and ignition used the same key - trunk and glove box used another key.

Mine (56 customline) uses one key for doors, ignition and glove box, another for the trunk and another for the gas cap.

Thanks paul2748 and also RCM, I knew one lock was door, the second lock cylinder I now know is ignition.

Just posting this because I stumbled across the picture.
(When new) the doors & ignition use a square-headed key and the glove box & trunk use a round-headed key.
