Alarm system keep going off ,only way to turn it off is adjust battery or unhook the battery.

Did you try double tapping the door open button to stop the alarm.

If it keeps going off you need to visit a dealership if it is a factory alarm or an alarm installer if it is an aftermarket alarm.

I need to disable the factory installed alarm. It keeps going off randomly. Suggestions?

Unhook the battery, light the car on fire, blow it up, or you could find the wiring diagram and just unhook the fuse for the alarm system. Or just find out where the power input is. If you disconnect the power it might go off though because of backup power module but if you unhook the battery for like 30 seconds and then do it it shouldnt beep at you. Good luck!

Alarm keeps going off

did you unhook the battery before you changed the starter ?. regardless unhook the battery for about ten minutes to reset the computer on your car then hook it back up.... if you have an anti-theft stereo make sure you know the code and how to enter it first.

Security alarm problem

Do you have the key fob? Alot of alarms will go off if you unhook and rehook the battery. All you should have to do is disable the alarm after you unhook the battery. Is this a factory alarm or an aftermarket one?
