Remote keyless entry system - replacing batteries
If the range of the transmitter is noticeably reduced, this indicates that the battery is weak and should be replaced.
To replace the battery
Remove the cover by carefully prying up its rear edge with a small screwdriver
Replace the battery with a new 3-volt, CR 2032 battery. The battery should be inserted with the plus side upward.
Avoid touching the contact surfaces of the battery with your fingers.
Press the cover back into place. Ensure that the rubber seal seats correctly to help prevent moisture from entering the
unit.
NOTE: The old battery should be disposed of properly at a recycling center or at your Volvo retailer.
WARNING!
Volvo does not recommend using the transmitter to lock the doors from inside the car. The alarm would be activated
and would sound when one of the doors is opened. The doors must not be locked using the remote transmitter while
the vehicle is occupied. In case of an accident, this may hinder rapid access to the occupants of the vehicle. The
alarm will also sound.
