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

the key in the driver's door lock. The master key should be used only if it is not possible to unlock the trunk via the
central locking system.

Press the key into the upper or lower edge of the cover over the lock in the trunk lid.
Move the key upward or downward to remove the cover.
