Audi is the brand where "it is an A4, so it takes the A4 key" causes the most wrong orders. The A4 name has spanned three different key bodies. So has the A3, and so has the Q5. What decides the fit is the shape of the key and where the buttons sit.
1. The flip key
A slim body with a blade that swings out when you press the release. Buttons sit in a row along the top face. This is the older Audi key, found on the previous-generation A3, A4, A6 and Q-series cars.
A cover for a flip key has to clear the hinge and the blade travel, so it is cut quite differently from the newer shapes.
2. The chunky rectangular key
Deeper and squarer, with the blade hidden inside and released separately rather than folding out. The four rings sit on the front face and the buttons are set into the side or the face depending on the exact version.
This is the most common Audi key on the road right now - the one on recent A3, A4, A5, Q3, Q5 and Q7 cars. It is also the one with the most sub-variants, which is why our Audi listings are split by style rather than by model name.
3. The newest key
Slimmer again, with a cleaner face and a different button arrangement. Found on the most recent cars and on much of the e-tron range.
Why we list by "Style A / B / C" instead of by model
Because listing by model would be a lie. One Audi key body appears across half a dozen model names and two decades of cars, while a single model name can cover three different keys. Splitting by shape is the only honest way to do it - and it is why every listing leads with a fitment photo rather than a compatibility table.
The thirty-second check
- Does a blade fold out of the body? → flip key.
- If not, is the body deep and squared off, or slim and flat?
- Where are the buttons - on the face, or on the edge?
Compare against the photos in the key fob cover fitment guide, and send us a picture if two look close. We confirm before anything ships.
Which finish
Alcantara suede is the biggest seller, and it is the natural match for an S-line or RS interior with suede on the wheel and seats. Leather suits the more conservative cars. Carbon fiber suits the S and RS cars, and where a vented version exists for your key shape we recommend it - the vents keep the antenna area open.

Frequently asked questions
Why do your Audi listings say Style A, B, C instead of model names?
Because one Audi key body spans several model names, and one model name spans several key bodies. Splitting by shape is the only accurate way to list them.
Will an A4 cover fit a Q5?
Sometimes - Audi shares key bodies across model lines. Match the fitment photo, not the badge on the car.
Does the e-tron use a different key?
Much of the e-tron range uses the newest, slimmer key. Check the fitment photo before ordering.
Can I still use the emergency blade with a cover fitted?
Yes. The blade still releases on every Audi cover we make.
