Horn when unlocking - still

[SPK]

Hi All,

I have just got a FL2 (MY13) 8 months ago - everything is great and we have given it a real test ...but in the last week the horn started going off when we unlock the car. It suddenly started, I have changed the battery in the smart key, all doors and locks are properly closed/on. It is very frustrating. Any ideas??

No idea but is there any way unlocking the doors may be triggering the alarm? If it was mine I'd disable the security system (pull fuse?) and see if that makes a difference.
