Replacing the key's battery

Updated 2022-05-10

The battery in the key must be replaced when it is discharged.

Note

All batteries have a limited service life and must eventually be replaced (does not apply for Key Tag). The battery's service life varies depending on how often the vehicle/key is used.

The key battery should be replaced if

the information symbol illuminates and the message Vehicle key bat. low is displayed in the instrument panel
signal reception repeatedly fails even when the key is within 20 meters (65 feet) from the vehicle.

Note

Move closer to the vehicle and try to unlock it again.

The battery in the smaller key without buttons1 (the Key Tag) cannot be replaced. A new key can be ordered from an authorized Volvo workshop.

Important

An end-of-life Key Tag must be turned in to an authorized Volvo workshop. The key must be deleted from the vehicle because it can still be used to start the vehicle via backup start.
