2005 infiniti coupe stock alarm randomly goes off. Is there a way to deactivate it?

It appears that one of the brackets on the hood is bent and this is the cause of my alarm going off every few hours. I looked in the drivers manual and it has nothing on deactivating the car alarm. Can I deactivate the alarm by locking the car with only the key or from locking it from the inside? Also, I have read something about turning down the sensitivity on the car alarm under the hood, but I thought this was only possible on custom alarms. Anything would be useful because my neighbors are starting to become hateful. If it comes down to it, I will just leave this 40,000 car unlocked, but I will not be happy about it.
