Opel Astra J 2014 - Alarm problem

[sebbat]

Sometimes alarm goes on. Even if don`t close the car - horn sounds and hazard start blinking after 10 minutes when I just close door (locks stay opened). Sometimes just hazard lights starts blinkin and can be off only if I press hazard light switch. Sometimes after 10 minutes Horn sounds and car just closed... Something wrong with BCM ? I check it - not water inside, its dry... Movement sensors I unplug connectors, so its not it... After 10 minutes I heard long horn beeee, thats usually not sounds, when I close or open car from remote.
