Car Alarms: 1998 Nissan Altima GXE alarm chirping, nissan altima gxe, nissan altima

Question
My 1998 Nissan Altima GXE's J2 alarm system recently started randomlly
"chirping" along with automatically causing the door locks to toggle on and
off.

I checked the fuse box, and there are no fuses present in the locations
allocated for 'anti-theft1 and anti-theft2'.  The only way I have temporarily
stopped this is by disconnecting the car battery.

How do I disable the alarm system to stop this very annoying problem?

Answer
It's an after market system
from your description.

To try to disarm it, locate and use the
valet/overide switch.

To start, look under the dash area for a button or,
a toggle switch. When you locate it, turn on the
ignition key, press and hold in the button (little
spring loaded micro button, red or black possibly)
until the alarm chirps 1 time. This should over ride
the system, and only the keyless entry part,
if installed, would still be operating.
The LED (light emiting diode) light in the dash
should also go on solid.=VALET/OVERIDE

This stops the alarm except for the keyless
entry if installed. The next step is to
either remove the alarm or, try to identify,
and get new remotes for it.

But once in Valet mode, it will allow the car
to start and operate like there was no
alarm at all. Repeat steps to put into user
mode.

Let me know how it goes.
