Often Asked Questions (FAQ)

Can I configure a new Audi key myself?

For most Audi designs produced after 2005, the answer is no. The car requires specialized software application (like ODIS or VCDS) and access to secure PIN codes to connect the key to the immobilizer. DIY programming is normally limited to the keyless entry functions on much older designs.

Does a brand-new key included the emergency blade cut?

If bought through a dealer, the physical emergency blade generally comes pre-cut based on the VIN. If purchased through a locksmith professional, they will use a laser-cutting machine to replicate your existing blade or cut one to code.

What should I do if I find my old key after getting a replacement?
