Question 1

Are you licensed and insured to work on Audi vehicles?

Accepted Answer

Yes. EZ Car Keyz is a California BSIS licensed locksmith company, fully insured, and credentialed through NASTF as a Vehicle Security Professional. That NASTF credential matters on a car like the 2016 A3 because accessing immobilizer data through legitimate channels requires verified identity and a paper trail. Audi key work also involves the vehicle security system and component protection, which are not things a general locksmith with a basic key machine can navigate. We operate under a real business name, show up in a marked vehicle, and you can verify us before we ever touch your car.

Question 2

How do I know you are not a scam locksmith?

Accepted Answer

Legitimate concern, especially for Audi work where the job is never cheap. The scam pattern is predictable: a generic Google listing, a low number quoted over the phone, then the tech shows up and the price multiplies at the car with add-on fees you never agreed to. Some owners have reported walking away paying four or five times the original quote with no recourse.

EZ Car Keyz has over 100,000 followers across YouTube and TikTok where you can watch us do this exact category of work on European vehicles. The price I give you on the phone is the price you pay. I show up in a marked van, I carry a real business license number you can verify with the California Bureau of Security and Investigative Services, and I give you a firm quote before I start. If the scope changes for any reason, I tell you before I do anything.

Question 3

Will the replacement key work exactly like the original?

Accepted Answer

Yes. The replacement is cut to your vehicle and programmed to match. Lock, unlock, and the other buttons on the 4-button remote all get tested before I leave. The transponder gets enrolled to the immobilizer so the engine starts normally.

One thing worth knowing: if your car has been sitting with a drained battery, or had a battery disconnect recently, you may get a key-not-detected warning or the remote stops responding even though the key itself is fine. That is a vehicle-side issue, not a bad key. I check both before assuming anything needs to be replaced.

Question 4

I bought a replacement flip key online for my 2016 A3. Can I program it myself or do I need someone with tools?

Accepted Answer

You need someone with the right diagnostic equipment. There is no ignition-turn sequence or button trick that adds a new key to the 2016 A3. The immobilizer enrollment has to be done through the OBD port with professional-grade software. The key blank you bought online can absolutely be used, we can cut and program it, just know the programming step is not a DIY job on this car. Bring the key and the car.

Question 5

My 2016 A3 flip key remote stopped working but the car still starts fine. What is going on?

Accepted Answer

This is a common split failure on flip keys and it almost always points to the remote side rather than anything serious.

The remote circuit and the ignition/start circuit operate independently. When the remote stops working while the car still starts, the first thing to check is the CR2032 battery. A weak cell can drop range to almost nothing or cut remote function entirely while still putting out enough signal for the transponder to communicate at close range in the ignition cylinder. Swap the CR2032 first.

If a fresh battery does not bring the remote back, open the key housing and look at the battery contact tabs. On these fold-out key designs, the contacts sometimes lose tension over time and sit loosely against the battery even when it looks seated. Bending them back into firm contact sometimes fixes what looks like a dead remote.

If neither of those works, the remote portion of the key may have a failed board or antenna. At that point the key still starts the car but the remote is done. A replacement gets you both functions back, and I can handle that on-site in Wagon Wheel or wherever the car is in Oxnard.
