The Audi Advanced Key is a keyless entry and push-button start system that allows you to lock, unlock, and start your vehicle without removing the key fob from your pocket or bag[1]. It uses proximity sensors in the door handles and trunk to detect the key within approximately 1.5 meters (5 feet) of the vehicle[2]. As of the 2025 model year, Audi Advanced Key comes standard on most models in the US lineup[3].
How the Audi Advanced Key Works
The system operates through radio frequency communication between the key fob and sensors embedded throughout the vehicle[1]. When you approach your Audi with the key in your possession, the car’s proximity sensors detect the unique signal from your key fob[4].
Unlike traditional keyless entry that requires pressing a button on the fob, the Advanced Key allows hands-free operation[2]. The door handles contain capacitive touch sensors—simply touching the sensor on the outside of the handle locks the vehicle, while placing your fingers behind the handle as if to open it triggers the unlock function[2].
Once inside, starting the vehicle requires only pressing the brake pedal and pushing the engine start button on the dashboard[4]. The system continuously verifies the key’s presence, preventing the engine from starting if the authenticated key is not detected inside the cabin.
Key Features of Audi Advanced Key
Keyless Entry and Exit
The core functionality allows completely hands-free vehicle access[2]:
- Unlocking: Place fingers behind any door handle to unlock instantly
- Locking: Touch the sensor on the exterior handle to lock all doors
- Extended lock: Hold the sensor longer to automatically close all windows and tilt the panoramic sunroof closed[2]
- Mirror folding: Locking can trigger automatic wing mirror folding if enabled in vehicle settings
Hands-Free Trunk Access
Many Audi models equipped with Advanced Key include a foot-activated trunk release[2]. By swiping your foot under the sensor located below the rear bumper, the trunk opens or closes automatically. This feature proves invaluable when carrying groceries, luggage, or sporting equipment. If your hands are full and you’re considering an SUV, understanding the Audi Q7’s towing capacity may also be relevant.
Push-Button Start
Rather than inserting a physical key, the Advanced Key enables push-button ignition[4]. With the key anywhere in the cabin—pocket, purse, or cupholder—simply press the brake and push the start/stop button. This eliminates fumbling for keys in low-light situations or when wearing gloves.
Remote Window and Sunroof Control
The key fob itself retains traditional button functions with added capabilities[2]:
- Hold unlock button: Lowers all windows and tilts open the panoramic sunroof
- Hold lock button: Closes all windows and sunroof
- Standard buttons: Lock, unlock, and trunk release functions still work via button press
This feature allows pre-ventilation on hot days before entering the vehicle.
Personalization Settings
The Advanced Key can store driver preferences linked to each individual key fob[4]. When you approach the vehicle with your specific key, the car can automatically adjust:
- Seat position and lumbar settings
- Mirror angles
- Climate control preferences
- Radio presets and audio settings
This personalization means family members with different key fobs each experience their own saved configurations.
Standard vs Advanced Key Comparison
| Feature | Standard Audi Key | Audi Advanced Key |
|---|---|---|
| Remote lock/unlock | Button press required | Hands-free touch sensor |
| Engine start | Button press required | Push-button (key in proximity) |
| Trunk access | Button press or handle | Foot-activated sensor |
| Window control | Not available | Hold lock/unlock buttons |
| Proximity detection | No | Yes (within ~5 feet) |
| Driver personalization | Limited | Full profile storage |
The standard Audi key still offers remote locking via button press, but requires physical interaction[1]. The Advanced Key eliminates this step entirely when the key is on your person[4].
Which Audi Models Include Advanced Key
For the 2025 model year, Audi has made the Advanced Key standard equipment across most of its US lineup[3]. This represents a significant change from previous years when it was often an optional upgrade or part of a convenience package.
Models with standard Advanced Key (2025):
- Q5, SQ5, Q7, SQ7, Q8, SQ8, RS Q8
- A4, S4, RS4
- A5, S5, RS5
- A6, S6, RS6
- A7, S7, RS7
- A8, S8
- e-tron GT, RS e-tron GT
- Q4 e-tron, Q8 e-tron
For pre-2025 models, availability varies by trim level and package selection. The feature was typically included in Convenience packages or Premium Plus/Prestige trims[5]. Buyers of a 2024 Audi A4 or earlier Q5 models should verify whether their specific configuration includes Advanced Key.
Replacement Cost and Programming
Replacing an Audi Advanced Key is significantly more expensive than a traditional key due to its sophisticated electronics[6]:
| Service | Dealership Cost | Locksmith Cost |
|---|---|---|
| New key fob | $360–$500 | $280–$400 |
| Key programming | $150–$200 | $75–$150 |
| Total cost | $500–$700+ | $350–$550 |
Dealerships typically charge $500–$900 for a complete replacement including programming[6]. Some owners have reported costs exceeding $700 for newer models with more advanced security features[7].
Automotive locksmiths specializing in European vehicles may offer savings of $100–$200 compared to dealer pricing[8]. However, Audi monitors key programming through the vehicle’s VIN, and proof of ownership may be required[9].

Customizing Advanced Key Settings
The Advanced Key behavior can be adjusted through the MMI infotainment system[2]:
- Navigate to Car menu on the dashboard
- Select Car Systems
- Choose Vehicle Settings
- Access Central Locking options
Available customizations include:
- Single-door unlock (driver door only) vs all-door unlock
- Automatic relocking if doors aren’t opened within a set time
- Acoustic confirmation sounds for lock/unlock
- Mirror folding behavior when locking

Frequently Asked Questions
Does Audi Advanced Key include remote start?
No, the Audi Advanced Key does not include remote engine start functionality[1]. Remote start is a separate feature available through the myAudi app on 2024+ models with Audi connect CARE. For older vehicles, remote start must be added through aftermarket installation[1]. Learn more about whether Audi can have remote start.
Can I add Audi Advanced Key to a vehicle that doesn’t have it?
Retrofitting Advanced Key to a vehicle not originally equipped with it is technically possible but expensive[5]. The installation requires new door handles with sensors, control modules, and professional programming. Costs typically exceed $2,000–$3,000 for parts and labor, making it impractical for most owners.
What happens if the Advanced Key battery dies?
The key fob contains a physical emergency key blade that can manually unlock the driver’s door[4]. Once inside, place the dead key fob against the steering column near the start button—the backup inductive charging system can read the key’s transponder to allow engine start.
Is Audi Advanced Key secure against relay attacks?
Like most keyless entry systems, the Advanced Key is potentially vulnerable to relay theft, where criminals amplify the key signal from inside your home[4]. To mitigate this risk, store keys in signal-blocking pouches (Faraday bags) or away from exterior walls. Some Audi models allow you to disable the passive entry function while retaining push-button start.
How far away does the Advanced Key work?
The proximity sensors detect the key within approximately 1.5 meters (about 5 feet) of the vehicle[2]. The trunk kick sensor has a similar range. Remote button functions (lock, unlock, trunk) typically work from 50–100 feet depending on environmental conditions.
