Start by inspecting the battery in your key fob. A simple battery replacement can often resolve the issue. Open your key fob and replace the battery with a new one. This is usually a CR2032 battery.

Sometimes, issues arise from outdated software. Ensure your Volvo EX90’s software is up to date. You can check for updates through your vehicle’s settings or consult your dealer for assistance.
4. Test with Backup Methods
If the digital key remains non-functional, use your traditional key fob to access the vehicle. This can help you determine whether the issue is with the digital key or the vehicle itself.
⚠️ Safety Note: If your key fails while driving or you cannot access your vehicle, seek assistance immediately. Avoid attempting any repairs that may compromise your vehicle’s security.
Backup Methods for Accessing Your Volvo EX90
In case your digital key is not working, having backup methods is crucial. Here are some reliable alternatives:
Using the Traditional Key Fob
The traditional key fob can be used to access and start your vehicle in emergencies. Ensure you always carry it with you as a fail-safe option.
Smartphone App Access
If your Volvo EX90 supports a mobile app, you may be able to unlock and start your vehicle from your smartphone. Ensure the app is installed and functioning correctly.
Repair Choices and Costs for the Volvo EX90 Digital Key
Depending on the diagnosis, you may need to consider repairs for your digital key system. Here’s what to expect:
Key Fob Replacement
If your key fob is damaged beyond repair, a replacement may cost between $200 to $400, depending on your location and dealer pricing.
Software Update or Repair
Updating software at a dealership can range from $100 to $200. If the issue involves more extensive repairs, costs can increase significantly.
Professional Diagnostics
For persistent issues, it might be necessary to seek professional diagnostics. This service typically costs between $75 and $150, depending on the service center.
Understanding the Immobilizer System
The immobilizer system is a key component of your Volvo EX90’s security. It prevents the engine from starting without the correct key. Understanding how this system works can help you troubleshoot more effectively.
How the Immobilizer Works
The immobilizer uses a transponder chip in the key fob, which communicates with the vehicle’s electronic control unit (ECU). If the signals do not match, the engine will not start.
Common Immobilizer Issues
Issues with the immobilizer can arise from a malfunctioning key, damaged wiring, or ECU problems. Diagnosing these requires specialized equipment, usually available at dealerships or certified repair shops.
