Replacing the battery in the remote control key

Updated 08/06/2023

The battery in the remote control key needs to be replaced when it has become discharged.

Note

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

The battery for the remote control key should be replaced if:

the information symbol illuminates and the message Car key battery low See Owner's manual is shown in the driver display

and/or

the locks repeatedly do not react to signals from the remote control key within 20 metres from the car.

Note

Always try moving closer to the car and making another unlock attempt.

The battery in the button-less key1 (Key Tag) cannot be replaced - a new key can be ordered from an authorised Volvo workshop.

Important

A discharged Key Tag must be handed over to an authorised Volvo workshop. The key must be deleted from the car since it is still possible to use it to start the car via back-up start.
