Car Alarms: 1999 Nissan Altima (Anti-Theft System), nissan altima, battery cables

Question
I have 1999 Nissan Altima. Recently the battery in it died, so I replaced it with a good working battery. As soon as I connect the terminals to the battery post the headlights flash on/off and the horn beeps on/off.

I have a single key that works the car and starts it.

I bought the car used and did not get any wireless alarm device that can be used to turn alarm off.

When the headlights flash/horn blows I immediately run to try and start the car but it does not roll over.

Is there any suggestions on how I can get pass this to start the car?

Regards.

Answer
Ok, you'll need to "set it off" by putting
the battery cables back on.

Normally, you would insert the key in
the drivers door, turn left, then right
to disarm and reset it. If yours is malfunctioning,
you can disable it for good by doing the following:

The FACTORY ALARM DISARM WIRE IS
green/yellow |-| at the smart entrance control.
The smart entrance control unit is located to the
right of the steering column.  It is black or blue
in color.

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

Have a good day.
