How do you cut the alarm off with the remote? on 2002 Infiniti I35

What button on the remote key chain do I push to cut off the alarm? What makes the alarm go off when there's no reason? This just started about 2 days ago, now it's seems to be going off when ever.

sounds like an electrical problem of some sort.. is it an aftermarket or factory alarm system? usually the lock or unlock buttons on the remote should turn off the alarm, but sometimes you have to try the panic button. we can check out the system if you would like to bring it by our shop, 607 S. Victory Blvd, Burbank, CA 91502.. but please give us a call 818 846 2210
