Lost every Q5 key?
If every key to a 2009 to 2017 Q5 is lost, the comfort module holding the key data gets read, sometimes on the bench after it comes out, and the replacement is coded into it on the spot. That brings the price to $409, the $349 key plus $60, and the old keys stop starting the car. Ownership proof is needed: photo ID plus the Q5's registration or title.
When a 2018 or later Q5 has no key at all, the phone call decides the route. Some of these cars accept a fresh key in a longer session where they sit; others need a key or module that Audi builds for that VIN, which a dealer orders. The VIN tells us which before you pay anyone, and you get the list of documents the dealer counter will want.
