Ducati MULTISTRADA 1260S Owner's Manual page 250

The key has a RESET button (3) of the microprocessor
managing the electronic parts: if a key-on is not
possible because the key is not acknowledged by the
Hands Free system in active and/or passive mode,
press RESET button to re-enable the correct
operation of the key.
The active key contains a battery that must be
replaced when the key and the battery symbols are
displayed when the instrument panel is turned on.
Note
In this case, replace the battery as soon as
possible.
When the charge level goes below a certain limit, the
key can only work in passive mode, like the passive
key: in this case, the instrument panel will not display
any message.
