Wierd thing happend to me - I posted a topic saying my light below my clock had stopped flashing I was told to lock from passanger side which worked fine it started flashing

Got in it after work and to my suprise my alarm started going off I never knew I bloody had one in 2 years!!!

Now it only works if you lock from passanager and open from passanger if I open from drivers door the alarm goes off until I relock from passanger and open

Any ideas how thi sbloody thing works

Thanks in advance
