Disabling Alarm G-35

Hi, I just bought a used Infiniti G35 and the factory installed alarm kept going on throughout the night. Couldn't figure out how to disable it. The weather is pretty windy so I think that is what it causing it to go off. The remote keyless entry is factoried. Thanks for the replies and I feel stupid asking this, the dealer never told how or even if you can disable the alarm.

Did you ever figure this out? If so, please respond with what you had to do to either solve the issue or disable the alarm. I am having the same problem!

Thanks!!
