43The 10-digit code on an Audi key fob is typically found on a transparent plastic card provided with your new vehicle documents. This crucial security code allows Audi dealerships to programme replacement keys if yours are lost or stolen.
In the UK, Audi owners of models like the A3, A4 or Q5 will receive this code card when first purchasing their vehicle. The plastic card is usually included in the vehicle's documentation folder provided by the dealership. The 10-digit number is hidden under a scratch-off coating on the back of the card for security purposes.
If you've misplaced your code card, UK Audi dealerships can retrieve your key code using your V5C registration document and proof of ownership. For newer Audi models like the e-tron, some key information may be stored digitally in your MyAudi account.
Always keep your 10-digit code secure as it's essential for key replacement. Never share this code online or with unauthorised key cutting services. For security, Audi UK recommends storing the code separately from your vehicle keys.
