How do I confirm I am on the correct Union retro automobile keys page?
Every product listed on this page is a Union retro automobile replacement ordered by code. The page is filtered to Union only — each listing corresponds to a specific Union lock cylinder code for classic and vintage Union models. Selecting the product that matches the code stamped on your Union lock barrel or key shaft guarantees the correct blade profile for your cylinder.
Are Union retro automobile keys interchangeable with other classic car brands?
No. Union retro automobile keys are cut to codes specific to Union lock cylinders. Each manufacturer used a proprietary blade profile system during production — a key cut to a Union code operates only Union cylinders. Physical similarity in blade shape between vintage brands does not indicate compatibility.
How do I read the code on my Union classic vehicle lock right now?
Locate the alphanumeric sequence stamped on your Union lock barrel face or original key shaft.

If the code is unreadable on the barrel, check the original Union vehicle documentation or logbook. If still unreadable, send a photo of your Union lock face to mr-key.com — the correct code series can often be identified from the photo.
