Often Asked Questions (FAQ)

Can I program an utilized Audi A4 key I purchased on eBay?

Most of the times, no. Audi keys are typically "locked" to the very first VIN they are set to. While some sophisticated locksmiths can "unlock" or "virginize" particular chips, it is typically more pricey than buying a new, unprogrammed aftermarket key.

Does my Audi A4 have a valet key?

My key fob buttons quit working; do I need a whole brand-new key?

Not necessarily. If the car still starts when the key is in the ignition or near the sensing unit, the problem is likely just a dead CR2032 battery or a failed remote circuit. Replacing the battery is a simple DIY task that does not require re-programming.

How long does the replacement process take?

If a locksmith professional is on-site, it usually takes 30 to 60 minutes. If the dealer has to order a key from the factory, it can take 3 to 7 company days for the part to arrive, followed by an hour-long service visit.

Will insurance coverage cover the cost of a replacement key?
