The alarm on my Kadjar activates at random times.  If I didn't hear it at the time, when I unlock the car it beeps four times, which I believe is a door sensor. 
It was was with my Renault garage for four days last July and they eventually replace a door sensor.  All was well. 
The it began alarming in April 2021 and it went back to the same garage.   Five days later and they had found nothing.  No history is recorded by the on board computer.  Plus it didn't alarm once while it was with them..  They suggested as a guess, that they replace the alarm siren but as this guess was to cost almost £600 it didn't happen.
All was well for a few weeks and it has now stared again, 
Ideas and suggestions, Please.
 

I had the same and it was a tilt sensor, covered under warrenty so unable to advise how much this would cost. 

I believe I have now fixed the problem.
As low mileage user I had queried with my Renault dealer whether the battery was causing the alarm to activate and was assured that the battery was fine and not causing the problem.
I stopped using the Stop Start by switching it off every time I used the car.  I also took the car on a long run.
Its now been a month and no more alarms. 
Shame the Renault main dealer could not figure this out.
