Car Alarms: 1990 Nissan maxima factory security, silver dots, nissan maxima

Question
We bought a 1990 Maxima from a dealer who went out of business. He bought it from an auction. We noticed, thast it has one of those security systems that have a series of numbers to punch in under the door knob. Without having to spend a small fortune at the nissan dealer, is there a way that we can reset it and put in a new security code. We're afraid if we touch the door wrong, an alarm will go off, so it sits in the driveway until we know more about it. Also...is it normal for a red "security" light on the dash to blink? I would appreciate any help, as wee are both retired and on a budgeted monthly income.  Thank You...Jim

Answer
ok, unfotunatly reseting the code on the door
is not the issue. A malfunctioning factory alarm
seems to be. You need to render it inert.

Get out some basic install tools or get
a friend or a good technician
in there to do this.

Normally, you would insert the key in
the drivers door, turn left, then right
to disarm and reset it. Yours was reset.
Try key in the drivers door, turn left, then
right to diasrm and unlock. If no joy,
you can disable it for good by doing the
following:

The FACTORY ALARM DISARM WIRE IS
light.green/blk with silver dots at the theft warn mod.
The Theft Warning Module is located to left of steering column.
It actually says Theft Warning on module.

Once Located, splice into this wire with
a simular guage wire, and put it to
a solid chassis ground. This terminates
the OEM alarm functions entirely.

However, at this point, this car would be exceedingly
easy to steel, so I suggest you get an aftermarket
alarm system to protect it from here on in.

If you have already have an after market alarm
however:

(SIREN & FLASHING PARKING LIGHTS= AFTER MARKET
or is it:
CAR HORN & FLASHING HEADLIGHTS= OEM-FACTORY)

Then look for the over ride/valet button under
the dash area, probably to the left leg region,
drilled into the plastic kick panel.

Then it's: KEY ON, PRESS AND HOLD IN BUTTON FIRMLY
UNTIL THE SIREN CHIRPS ONCE, AND THE PARKING LIGHTS
FLASH. THEN KEY OFF.

This is over ride, and the car should start.
The only thing that would work would be keyless
entry if it is installed. The alarm functions
have been suspended.

Let me know which applied to your issue.

Good luck.
