Default Disable factory alarm

Is there a way to disable factory alarm on H3? Sometimes when I open the door the factory alarm goes off even tho there is an after market alarm system. So if anyone can tell me how to disable the factory alarm complexly would be amazing!

Press UNLOCK on the oe rke=disabled. I rarely lock my doors, when I do with the rke, it activates the theft-deterrent system.

The only way to arm the factory alarm is to lock the H3 with the remote. The owner's manual explains it. If you unlock (disarm) using the OEM remote, then NEVER use the remote to lock it, the factory alarm will remain deactivated.

If you have indeed unlocked it (using the remote) and then never locked with the remote, and it's still happening, then your aftermarket alarm is not playing nice with the H3's electronics (not the first time issues with aftermarket alarms have been reported).
