Car Alarms: How to disable a Nissan Sentra 2002 OEM alarm, nissan sentra 2002, nissan sentra

Question
I replaced the battery on my car  and once I connected the new one, the alarm turns on and doesn't allow me to atart the car. I don't have the original Keyfob.  Is there a way to disable the alarm?

Answer
It's likely to be an after market system.

To try to disarm it,
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. Once in Valet mode,
it will allow the car to start and operate
like there was no alarm at all.

The next step is to remove the alarm.
This might require a local technician to
identify it, and affect neccesary service for you.

That should solve the troubles.

Let me know what you discover.
