Car Alarms: 1995 Nissan Altima factory security system, nissan altima, keyless entry system

Question
Hello,
My daughter has a 1995 Nissan Altima that has a factory installed security system. We purchased this car last year and the previous owner told us that the alarm would go off at time, and you could stop it by putting the key in the outside door lock and turning it. This did happen and that did fix it, however a few days ago the car stopped on her in the road. The shop working on the car thinks the security system has shut the car down and will not let it start. The Security system light on the dash only blinks when trying to start the car, the car will turn over but will not start. Any information and help you can provide will be Greatly appreciated.

Thank you,
Mack

Answer
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.
There is a light green/red wire, that when you use a
single negative pulse to the unlock, this wire will disarm
without unlocking.

This can only be achieved 3 ways:

1. Use key in the drivers door, turn left,
then right to disarm and unlock.

2. Add an after market keyless entry system to emulate
the factory remote functions. I have several models
if this option suits you.

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

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

The standard method to disableis 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 emiting 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.
