Nissan Leaf alarm randomly goes off - and stops

[Pistonheadsdicoverer]

As per title.

Nissan Leaf alarm has gone off and stopped after about 30 seconds. It did it last week as well.
What could be the cause? Car is new (November 2024, 74 plate), has done about 3000 miles. TIA for pointers.

Fly in the car?

Maybe could disable the interior alarm, to eliminate that from the issue?
