Disc 3 - Alarm keeps going off - unknown reason

Hi all, every evening I return home from work park up and lock disc 3. Do a few jobs around the garden then feed cats and dogs all is fine but about Half hour or more later every night the alarm goes off, drives the neighbours mad!
But it never seems to go off at work only on my drive. And not straight away - it waits till I have just settled down in house then starts. I have checked all windows and door are shut tight, someone suggested I might have a mouse in the car somewhere but if that was the case would it not happen at work or at other places also? I am bemused. Anyone have any ideas?

some nasty neighbour coming along and rocking your car once you are safely back indoors?
Do you have a Ring doorbell or summat?

Moths only come out at night. I had this problem and could not figure it out as it only hapend at night, and when jumping in the car to think about it, it literaly hit me in the face.
