Can't shut off alarm totally. It goes off every day. How do I shut it off.

Disconnect back up battery and main battery.,

Aftermarket alarm system?? If so it could be anything with that alarm. If it's the factory security system, this is totally normal. When you disconnect the battery and reconnect it, the system resets and automatically "panics" because it saw the power failure. If it's the factory system, simply have the key fob handy to turn it off after you connect the battery. If you don't have a remote fob, just put the key in the driver's door and unlock it. This will override and shut off the system.

your alarm has a problem mayb with the wiring or the sensitivity of your alarm is so high thayt as soon as you close the door it goes off take it to the local garage for a wiring check up

good day

I just have to say, we bought the same watch in 2014, at a Meijer store. The directions were totally incomprehensible, and this watch has spent every day since in a drawer where the alarm goes off at the same time each day because 4 intelligent adults can't figure out how to change the settings. Ridiculous.

The usual cause of this is the alarm switch on the bonnet panel is too low and creeps up when you leave the car .

Just put some washers behind it so its snug when the bonnets shut down - I have done a few like his and its easier than disconnecting .

disable the hood microswitch. just unplug it. That and the cabin sensor are the most probably reasons the alarm will go off.
Alarms are useless. Totally effin useless. So it goes off.....then whaddya going to do. Shoot someone? Call the police? or listen to it drain the battery over and over again.
But....you can't disable the alarm totally. The bmw engineers have tied it into the main computer. you can however disable the sensors one by one so it doesn't set off the alarm. Hood sensor....Hood sensor....that's the culprit.
