The Blazer EV represents the Chevrolet commitment to blending cutting-edge technology with everyday practicality. Among its numerous advanced features, the Digital Key Sharing capability is a particularly convenient innovation for modern drivers. This technology transforms your compatible smartphone into a secure digital key, allowing you to access and operate your Blazer EV without the traditional key fob.

What is Digital Key Sharing?

The Digital Key feature for the Blazer EV allows owners to use their smartphone as a virtual key through the myChevrolet mobile app. This technology establishes a secure connection between your smartphone and vehicle using a combination of Bluetooth Low Energy (BLE) and Ultra-Wideband (UWB) technologies for precise proximity detection.

What makes this feature particularly valuable is the sharing capability. As the primary owner, you can create and share digital keys with family members, friends, or colleagues, giving them temporary or permanent access to your Blazer EV. This eliminates the need to physically hand over a key fob when someone else needs to use your vehicle.

How Digital Key Sharing Works

The process begins with the primary owner setting up their Digital Key through the myChevrolet app. Once established, this primary key holder can generate additional digital keys to share with others. When creating a shared key, you can customize various parameters:

• Access Duration: Set time limits ranging from a few hours to indefinite access
• Access Level: Determine what features the recipient can control (driving only, climate controls, charging settings, etc.)
• Usage Monitoring: Track when and how shared key holders are using your vehicle

Recipients receive an invitation through email or text message, prompting them to download the myChevrolet app if they don’t already have it. After accepting the invitation and completing a verification process, the digital key becomes active on their smartphone.

The system uses sophisticated encryption to ensure security, with each digital key containing a unique digital signature that cannot be duplicated. The Blazer EV recognizes authorized digital keys when they come within range, allowing for passive entry where the doors automatically unlock as you approach.

What to Do if Your Digital Key is Lost or Broken

Despite the convenience of digital keys, issues can arise. Here’s how to handle common problems:

Lost or Stolen Smartphone

If your smartphone containing your digital key is lost or stolen:

• Immediate Deactivation: Log into your myChevrolet account from another device or computer and deactivate the digital key associated with the lost phone
• Remote Revocation: As the primary owner, you can instantly revoke any digital key from the myChevrolet app or web portal
• Temporary Key Fob Use: Revert to using your physical key fob until you can set up a new digital key
• Contact Customer Support: If you cannot access your account, contact Chevrolet customer support to assist with emergency deactivation

Broken or Malfunctioning Smartphone

If your smartphone is damaged or malfunctioning:

• Alternative Access: Use your physical key fob as a backup
• Transfer to New Device: When you get a replacement phone, download the myChevrolet app and sign in with your account credentials
• Re-authentication: Complete the verification process to reactivate your digital key on the new device
• System Reset: In some cases, you may need to delete and recreate your digital key from scratch

System Glitches or Connectivity Issues

If the Digital Key feature isn’t working properly:

• App Update: Ensure your myChevrolet app is updated to the latest version
• Vehicle Software: Check if your Blazer EV requires a software update (can be checked through the vehicle’s infotainment system)
• Bluetooth/UWB Settings: Verify that Bluetooth and UWB (if applicable) are enabled on your smartphone
• Force Close and Restart: Close the app completely and restart it
• Network Connection: Confirm your smartphone has an active data connection, as initial setup and some functions require internet access
• Factory Reset: As a last resort, you can perform a factory reset of the Digital Key system through the vehicle’s settings menu

Additional Security Measures

The Blazer EV incorporates several security features to protect your digital key:

• Biometric Authentication: Requires fingerprint or facial recognition before the digital key can be used
• Geofencing Capabilities: Set geographical boundaries for when shared keys will function
• Activity Logs: Review detailed logs of when your vehicle was accessed and by which digital key
• Multi-Factor Authentication: Adds an extra layer of security during the key sharing process
