Question 1

What is the cheapest way to handle all-keys-lost on my 2016 Audi A6?

Accepted Answer

Call a mobile locksmith who specializes in European vehicles before you call the dealer. Audi dealer quotes for all-keys-lost on this generation tend to be painful, and that's before towing a car that won't start. Owners on forums report quotes well into the hundreds, sometimes over a thousand, depending on the dealer and whether they count labor separately.

What makes this job expensive anywhere is the immobilizer. This generation uses an encrypted setup that requires reading the module, often off the bench, before new keys can be enrolled. That's legitimate technical work, and any honest specialist is going to charge accordingly. The difference is a mobile locksmith comes to your location, doesn't charge a towing fee on top, and typically comes in well under the dealer. We quote the full job on the phone and that's what you pay.

If you have even one working key, call now and add a spare. It's a fraction of the all-keys-lost price and buys you real peace of mind.

Question 2

Can you delete lost or stolen keys from my Audi so they can't start the car anymore?

Accepted Answer

Yes. When keys are programmed on this system, all previously stored key data gets wiped first. Only the keys physically present during that session get enrolled. A lost or stolen fob that isn't presented during programming gets erased and won't start the vehicle or trigger the comfort access on the door handles.

The system supports multiple keys per vehicle. We set the count to however many you want active. If you think a key was taken, this is the correct move.

Question 3

Does my 2016 Audi A6 smart fob have a hidden emergency blade inside it?

Accepted Answer

Yes. There's a small release button on the fob body. Press it and the metal blade slides out. That blade fits the driver door lock cylinder and lets you get into the car mechanically when the fob battery is dead or comfort access isn't responding.

Worth knowing: on some A6 door handles, the lock cylinder is covered by a small cap that pops off before you insert the blade. It's not broken, it's just how the door is designed. If your blade is worn, cracked, or missing entirely, we can cut a replacement from the key code without needing the original.

Question 4

My 2016 A6 comfort access stopped working on one door handle but the other handles are fine. Is the fob dying?

Accepted Answer

Probably not the fob. If other handles still respond and the car starts normally, the fob is communicating with the car just fine.

Comfort access on the A6 works through antenna modules built into each door handle. When one handle stops responding while the others work, the issue is almost always isolated to that door's antenna or the wiring feeding it, not the key itself. Dirt and moisture around the handle sensor area can cause intermittent behavior too, so wipe the handle down and retest before drawing any conclusions.

If the problem stays on one specific door handle no matter what fob you use, that points away from the key entirely.

Question 5

I bought a replacement fob online for my 2016 A6. Can I program it myself without a tool?

Accepted Answer

No. There is no button sequence or ignition-turn trick that will enroll a new smart fob on this vehicle. Programming requires diagnostic equipment communicating through the OBD port, and on this generation the immobilizer is encrypted, so the tool has to be the right one for the job. A generic cheap programmer won't cut it.

If you bought a fob online, it still needs a pro to pair it. Bring it along when you call, or just have us supply the blank. Either way works.
