Audi key fob battery guide: sizes, types and replacement tips
If your remote suddenly stops locking or unlocking the car, chances are you simply need a new Audi battery for key fob. Most modern Audi models – A1, A3, A4, A5, A6, A7, A8, Q3, Q5, Q7 and Q8 – use a single 3V coin cell inside the remote. With the tool above you can quickly check exactly what battery does an Audi key fob take for your specific model, year and generation.
Our database is structured as:
- Brand: Audi
- Model: A1, A3, A4, A5, A6, A7, A8, Q3, Q5, Q7, Q8
- Years / Generation: for example, Audi A4 B8 (2008-2016), A4 B9 (2017-2023)
- Battery type: usually CR2032 3V coin cell
- Quantity: 1 battery per key fob
- Notes: key type (flip key / smart key / proximity), OEM micro-cell part number, basic replacement instructions
So instead of guessing in a shop, you can use the finder, pick your car, and instantly see the exact type of battery for Audi key fob you need.
OEM part numbers and compatible replacements
Inside the tool, every Audi row includes an OEM battery part number. For the majority of CR2032-based remotes, this is:
- OEM: N10528301
- Description: genuine Audi/VW micro-cell battery, CR2032 3V coin cell for key fobs
You can use this OEM number to:
- order the original Audi battery for key fob from a dealer,
- or cross-reference it to premium third-party brands (Varta, Panasonic, Duracell etc.).
The finder also adds a direct shopping link based on the battery code (for example, “CR2032 battery”) so you can quickly find matching cells online.
Model Differences That Change the Procedure: Car key fob batteries for Audi
For most recent models, the car key battery Audi uses is:
- Battery type: CR2032
- Voltage: 3V
- Quantity: 1 per key fob
- Typical OEM part number: N10528301 (genuine Audi/VW micro-cell battery for remotes)
That means in the majority of cases a standard CR2032 Audi battery for key fob is enough. However, different generations may look similar on the outside, but use slightly different housings and internal layouts. That is why we always connect the battery type to:
- the exact model,
- the production years,
- and the generation / body code (for example, A6 C7 vs A6 C8).
Use the tool at the top of the page to check your combination before ordering.

An Audi model name alone does not identify every key housing used across its production run. Compare the physical fob, model year, and any readable part number before treating a battery listing as a match.
A technician handoff for Car key fob batteries for Audi is worthwhile when the correct part and procedure do not change the symptom, because the remaining fault is no longer a routine user adjustment.
