What to tell us about your A4

Share any key-not-detected message, whether a spare starts the car, and whether the issue began after a repair. Remote access and start authorization are separate symptoms.

  • Exact model year and trim.
  • Whether a working key remains, and whether the car starts.
  • Which remote or key functions work or fail.
  • Your town and where the vehicle is parked.
  • Any recent module, battery or electrical repair that may be related.

Year-specific compatibility

We assess U.S.-market model years. Equipment and key systems can change by year and trim, so this page does not promise a fit based on model name alone. Call with the exact vehicle details to confirm parts, programming path, service availability and quote before arranging a visit.

YOUR NEXT STEP

Tell us about your key.

A few details help us check compatibility and availability. Prepare a message, review it, then send it your way.

Prepare your vehicle service request
1. What do you need?
2. Your vehicle

Year is optional. If you do not know the make or model, use Not sure.

Choose a year and make, then start typing the model. You can always enter it yourself.

Optional model suggestions use the year and make only via NHTSA's vehicle catalog. No location, notes or ID numbers are included in that lookup.

3. Where is the vehicle?

Choose the county where the vehicle is parked. Town not listed? You can enter it yourself.

Your location and notes stay on this page until you choose to send the prepared message. The model lookup uses only year and make. This does not book an appointment.

Questions about the Audi A4

Which A4 model years can be assessed?

We assess U.S.-market years, but compatibility must be confirmed for the exact year, trim and key system.

Can an online A4 fob be programmed?

Possibly, but first confirm the part number, electronics and reuse status. A matching shell does not establish compatibility.

What should I have ready before calling?

Have the Audi A4 model year, trim, key status and vehicle location ready. If you already have a replacement fob, include its part number; a matching case does not confirm compatibility.
