Common Causes of Keyless Entry Issues in the Volvo V90
Several factors can lead to your Volvo V90 keyless entry not working. Identifying the specific cause will help in resolving the issue quickly.
Dead Key Fob Battery
A dead battery in the key fob is the most common reason for keyless entry failure. If the fob isn’t functioning, the first step is to replace the battery. Most key fobs use a CR2032 battery, which is readily available in stores.

Interference from Other Devices
Electronic devices can interfere with the signals transmitted between your key fob and your vehicle. Items like smartphones, metal objects, or even other key fobs can disrupt communication. If you notice the keyless entry issues only in certain locations, interference may be the culprit.
Physical Obstructions
Sometimes, physical barriers can obstruct the signal. Ensure you are within range of your vehicle and that there are no large objects blocking the signal path. Standing too far away from the car can also lead to connectivity issues.
Software Glitches
Software glitches in the vehicle’s electronic systems can sometimes prevent the keyless entry from working. Restarting your car’s electronic systems by turning it off and on can often resolve minor issues. For related context, you may also want to read Volvo XC60 audio not working.
Hardware Failures
In rare cases, the keyless entry system may have hardware failures that require professional assistance. Issues with the car’s receiver or the key fob itself may need expert diagnostics and repairs.
Steps to Diagnose Keyless Entry Problems
If your Volvo V90 keyless entry is not working, follow these steps to diagnose the issue:
Check the Key Fob Battery
Start by checking the key fob battery. Open the fob and replace the battery if necessary. After replacing, test the keyless entry functionality.
Attempt to Use the Spare Key Fob
If you have a spare key fob, try using it. If the spare works, the issue likely lies within the original fob.
Test for Interference
Move away from potential sources of interference, such as other electronic devices or metal objects. Test the keyless entry from different locations.
Inspect for Physical Damage
Check both the key fob and the vehicle for any signs of physical damage. Look for cracks, water damage, or any other visible issues.
Restart the Vehicle
Turn off your vehicle completely and restart it. This can reset the electronic systems and potentially fix minor software glitches.
Cost of Repairs for Keyless Entry Issues
The cost of repairing the keyless entry system in a Volvo V90 can vary based on the underlying issue.
Battery Replacement
Replacing the key fob battery is inexpensive, generally costing between $5 to $15.
Key Fob Replacement
If the key fob is damaged beyond repair, a new fob can range from $200 to $400, depending on the dealership or service provider.
Professional Diagnostic Services
If the issue is more complex, hiring a professional for diagnostics can cost between $75 to $150, depending on the service center’s rates.
Preventing Keyless Entry Issues
Preventive maintenance can help avoid keyless entry problems in your Volvo V90.
Regularly Check and Replace the Key Fob Battery
Make it a habit to check the key fob battery every few months, especially if you notice reduced functionality.
