Car Alarms: SECURITY ALARM ON 2000 NISSN QUEST, oem alarms, keyless entry system

Question
HOW DO I GO ABOUT DISABIING MY SECURITY SYSTEM? AT THE PRESENT, IT WONT ALLOW MY IGNITION TO START THE VEHICLE. IT BOESNT HONK THE HORN, BUT THE HEADLIGHTS FLASH, AND WHEN I TURN THE KEY NOTHING HAPPENS

Answer
Ok, a bit complicated & problematic.
 This system depends on the physical action
of the door lock locking and unlocking-arming and disarming.
If you have a factory remote, that would do this to
specifications. It is also designed to only disarm using
the OEM/FACTORY remote that came with it.

So, disarming this can only be achieved 3 ways:

1. Try this first, Use key in the drivers door, turn left,
then right to disarm and unlock. Most all Japanese OEM
alarms would disarm this way.

2. Add an after market keyless entry system to emulate
the factory remote functions. I have several models
if this option suits you. (However, it may not disarm
THIS particular model as it's designed to only
disarm using the RF signal from the original remote!)

3. Acquire or use & or, replace the original remote that
can control it as specified. This would be at the
local dealership parts department.

(This is why there is no wire you could ground
without affecting the door lock system.
A single negative pulse to the unlock wire will disarm
without unlocking, yes, but would always disable the
locking mechanism. Not good.)

Keep in mind, if this is after market
(siren and flashing parking lights)
then it's a different method entirely.

The standard method to disables as follows:

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 emitting diode) light in the dash
should also go on solid. If it's a toggle type,
then key on, flip the switch in the other direction
This would be OVERRIDE/VALET mode.

Repeat this process to toggle back to service mode.

Let me know what applies
to your issues.
