how do i disable my car alarm on a 2004 nissan Murano sl
If the alarm is sounding, you must use the master key on the driver side to shut the alarm off. Be sure that all the other doors are shut before doing so.
Normally, putting the key in the drivers side door lock,turning to the left, then to the right all the waywill unlock and disarm/reset the "OEM factory"alarm system.

Unplug the negative from the battery. Not sure why you bothered to answer this. The asker wanted to disable the system, not simply silence an alarm that was going off. Under the driver's seat is the unit that controls the security system. Under the carpet there is a module with a long plug. Pull that out and the security system is disabled. The caveat is that you may lose your power door locks using this method.

Under the front passenger seat, there is an electrical harness. Simply unplug the connection. This should disable the alarm.
