The Lincoln Nautilus supports digital key functionality, allowing vehicle access and engine start via a compatible smartphone. Digital key sharing enables an authorized owner to grant access to other approved users without handing over a physical key fob.

Lincoln Nautilus Digital Key System

The Nautilus uses a phone-as-a-key system that allows a compatible smartphone to function as a secure vehicle key.

Core system elements include:

• Near-field communication (NFC) or Bluetooth connectivity
• Vehicle access sensors in door handles
• Push-button start system
• Lincoln mobile application integration
• Secure authentication protocol

The system allows entry, locking, unlocking, and engine start without a physical key in hand.

Phone-as-a-Key Function

Phone-as-a-key enables:

• Passive entry when approaching the vehicle
• Lock and unlock functions via door handle touch
• Engine start once inside the cabin

The vehicle detects the authorized smartphone within proximity range.

Communication occurs through encrypted wireless signals.

If the smartphone battery is low, NFC backup functionality may allow door access by placing the device near a designated sensor area.

Digital Key Sharing Concept

Digital key sharing allows the primary vehicle owner to provide controlled access to another person through a smartphone-based system.

Instead of transferring a physical key fob, the owner can:

• Invite another user through the mobile application
• Assign access credentials
• Define permission limits

The invited user receives a digital key credential on their compatible device.

Access Permission Controls

Digital key sharing includes permission settings.

Possible access controls include:

• Full driving access
• Limited driving access
• Temporary access duration
• Revocable access rights

The vehicle owner can manage these permissions through the mobile application interface.

If access needs to be removed, the owner can deactivate the digital key remotely.

Security and Authentication

Security is central to digital key sharing.

The system uses:

• Encrypted communication protocols
• Device authentication verification
• Secure cloud-based credential management
• Multi-layer authorization steps

Authentication ensures that only approved devices unlock or start the vehicle.

If a device is lost, digital access can be revoked without replacing physical hardware.

Vehicle Start Authorization

Digital key authorization allows engine to start only when:

• An authenticated device is detected inside the vehicle
• Security verification is complete

The push-button start system interacts with digital key credentials before allowing ignition.

This function replaces the need for a traditional key fob in day-to-day use.

Integration with Lincoln Mobile Application

The digital key feature integrates with the Lincoln mobile application platform.

Through the application, owners can:

• Create and manage digital keys
• Send invitations to additional users
• Monitor vehicle access history
• Adjust permission levels

Digital key management occurs within a secure user account environment.

Multiple User Profiles

The Nautilus supports driver profile settings.

When a shared digital key is used:

• Seat position may adjust
• Steering wheel position may adjust
• Climate preferences may adjust
• Infotainment preferences may load

Profiles link to user credentials stored in the system.

This feature provides personalization without manual configuration each time.

Connectivity Requirements

Digital key sharing requires:

• Compatible smartphone device
• Updated operating system
• Active vehicle connectivity service

Wireless communication between the vehicle and smartphone relies on Bluetooth and NFC technologies.

If cellular connectivity is temporarily unavailable, local authentication via Bluetooth or NFC may still allow access.

Backup Key Options

Despite digital key capability, the Nautilus retains traditional access methods.

Backup options include:

• Physical key fob
• Keypad entry system (where equipped)
• Emergency mechanical key inside key fob

These alternatives ensure access if smartphone functionality is unavailable.

Digital key sharing supplements rather than replaces traditional security systems.

Temporary Access Scenarios

Digital key sharing supports temporary access scenarios such as:

• Lending the vehicle to a family member
• Granting short-term access to a guest
• Providing controlled access to service personnel

The owner defines duration and access scope within the application.

Temporary credentials automatically expire based on selected parameters.

Revocation and Access Management

Access revocation can occur instantly.

If a shared user no longer requires access:

• The primary owner removes the digital credential
• Vehicle recognition for that device stops
• Start authorization is disabled

No physical reprogramming of the vehicle is required.

This flexibility enhances control over vehicle security.

Data Privacy and Cloud Management

Digital key credentials store within secure cloud-based systems.

Privacy safeguards include:

• Encrypted credential storage
• Secure account authentication
• User-based access management

Vehicle access logs may be available through the mobile platform for monitoring.

Over-the-Air Software Support

The Nautilus includes over-the-air software update capability.

Software updates may improve:

• Digital key stability
• Connectivity performance
• Security protocol enhancements

Updates occur through vehicle connectivity systems.
