Mazda Repair Questions? Ask Mechanics for Answers ASAP
Sorry you are having this problem can be very annoying when this happens .
First remove the horn fuse ,this will cool down the neighbours .
Then i suggest you get to the dealer and have the car hooked up to a diagnostic scan tool and check the memory in the alarm system
which will keep records of which switch is activating and setting off the alarm .
Most common on your car is the drivers door switch ,there is an updated door lock for this issue .
Just to confirm me saying go to the dealer for a scan is due to the fact it could be any one of mant switched that has failed
and replacing on assumption would be costly and very time consuming .
Need further assistance then please get back to me with the replay button .
Kindest regards Greg
