Call (909) 455-3660Whether you drive a brand-new Audi A4 or an older one, Don's Locksmith can replace or duplicate your key at your location. The right key for your A4 depends on its model year — here's how Audi A4 keys have evolved.
Audi A4 Key Types by Year
| Model Years | Typical Key Type |
|---|---|
| A4 1996–1999 | Early transponder key — an early transponder (chip) key as immobilizers began appearing. The key must be cut and electronically programmed to the vehicle to start the engine. |
| A4 2000–2007 | Transponder key — a transponder chip key, sometimes combined with a separate remote. Both the cut and the chip programming must match your vehicle. |
| A4 2008–2013 | Remote head key / early smart key — typically a remote head key (key and remote in one) or, on higher trims, an early proximity smart key. Cutting plus on-board programming is required. |
| A4 2014–2018 | Proximity smart key — commonly a proximity smart key with push-button start on many trims, alongside transponder keys on base models. Programming uses the vehicle’s security system. |
| A4 2019–present | Proximity smart key / push-to-start — usually a proximity smart key with push-button start, and on some vehicles phone-as-key features. A replacement must be programmed to the car’s encrypted security system. |
Key technology varies by trim and region; call us with your exact year and VIN and we'll confirm the right key for your Audi A4.
