Audi model lists can help identify a likely key generation, but they are not the final fit test. The Vertical Layout and Tri-Layout cases follow visibly different control geometry and housings. The correct choice is the format that matches the key in hand from every side.
What ‘Vertical Layout’ means
The Audi Vertical Layout key case is designed around the modern smart-key shape shown in its gallery, with controls arranged along the main vertical axis. The listing references Audi A, Q, S and RS families using that pictured format.
Look beyond the badges in the compatibility text. Compare the outer silhouette, the top and bottom shapes, the exact control sequence and the rear emblem area.
What ‘Tri-Layout’ means
The Audi Tri-Layout key case follows a different key architecture with a three-part control geometry. Its current listing records compatibility across several A4, A5, Q5, A6, A7 and A8 generations when the physical key matches the gallery.
The tri arrangement, top detail, bottom emblem area and slim profile are the visual evidence. Do not select it simply because the car appears in a model list.
A side-by-side fit test
1. Compare the button geometry
Is the control map a single vertical sequence or a three-part arrangement? Check icon order and spacing, not only the total number of buttons.
2. Trace the perimeter
Compare corner radius, taper, top and bottom details, and overall thickness. A similar front view can hide a side profile that will not align.
3. Turn the key over
Match the rear panel, emblem position, seams and release points. The case must accommodate the physical structure, not only the button face.
4. Check all access points
Emergency-key release, battery access and any side control should remain aligned. Do not force the original components into the case.
Material options do not change the fit
Both current Audi listings offer Silver Finish and Sterling Silver as separate selections. Choose material only after the correct physical format is confirmed. Preserve the exact option labels in product copy and internal links.
Which Audi key case should you choose?
- Vertical Layout when the modern pictured housing and single-axis control map match.
- Tri-Layout when the three-part control geometry, top detail and rear structure match.
- Neither when the key differs on perimeter, controls, rear panel or release points; request a fit review instead.
Browse the verified Audi collection and use the premium key case buying checklist before ordering. Physical evidence is more reliable than a broad year range.
