Question 1

I lost all my Audi keys. Can you still make a new one?

Accepted Answer

Yes. All-keys-lost is one of the most complex calls we get on Audi vehicles, and we handle it regularly. On BCM2 equipped models like many A4, A5, A6, Q5, and Q7 models, we access the immobilizer module, extract the security data, generate new keys from that data, and program them to your car so the lost ones no longer work. The system wipes all previous keys and only registers the new ones you authorize. Audi dealers will tell you to tow the car in and can quote $800 or more for a single key. We come to you and handle the entire job on site.

Question 2

Do I need to tow my car to the dealer if I have no keys?

Accepted Answer

No. That is the dealer route, not the only route. Audi dealers require the car to be towed in for all-keys-lost programming, and owners on forums describe nightmare scenarios around it. One Q3 owner had the replacement key waiting at the service center but could not tow the car because it would not shift into neutral without a working key. An S4 owner was stuck because the tow truck could not get dollies into a narrow driveway. We bring professional Audi specific tools to your location and handle the BCM2 access, key generation, and programming right at your vehicle.

Question 3

How long does an all-keys-lost replacement take?

Accepted Answer

On BCM2 equipped Audi models, the electronic work typically takes about 30 minutes once we are set up at the vehicle. That includes accessing the BCM2 module, reading the immobilizer data, generating new keys, and programming them through the diagnostic port. Compare that to the dealer route where you are looking at a tow, waiting for a key to be ordered and authorized through Audi HQ, and a programming appointment that could be days or weeks out. We handle Audi all-keys-lost same-day in a single visit, typically under an hour from arrival to handing you a tested key.

Question 4

What battery does the 2015 Audi S4 key fob use?

Accepted Answer

The 2015 Audi S4 uses a CR2032 battery. You can pick one up at most auto parts stores or pharmacies for a few dollars. When we make a replacement key, we always install a fresh battery so you are starting with a full charge. Pro tip: once you have your new key, pick up a spare battery and keep it in your wallet or glove box. A dead battery on an Audi comfort access fob can drain faster than expected because the fob is constantly communicating with the car when in range.

Question 5

Can you make a spare at the same time so I have two keys?

Accepted Answer

Yes, and we strongly recommend it. Audi key programming works by setting the total number of keys you want and then teaching each one in sequence. The system wipes all previous key data and only registers the keys presented during that session. That means adding a second key during the same visit is far cheaper than doing it later, since a separate visit would require running the full programming session again. Audi supports up to eight keys per vehicle, and most owners going through an AKL situation choose to have us program two on the spot.
