1996 Nissan Maxima - unlock car, anti theft alarm went off and car won't start. Got new battery, battery was dead, put in new battery, anti theft alarm still going off and car won't start. Please help

you have activated the anti theft system.you need to have the remote to lock and unlock the car.
the other thing to try is lock and unlock the passenger door twice with the key

fault on a live connection,but check all your earths aswell

i believe if you put key in ignition turn it forward and back off twice it should reset the anti theft to start it. or unlock pass door with key and that might reset it. also try the same with back pass door if the other didnt work. hope this helps.

put the key in the door and unlock it that way. that should work.

It should be the same key for both and if u unlock the trunk with key the alarm should turn off so you can start . had the same problem . worse comes to worse have a key made at dealership or a portable locksmith come to you. about 80 for a key. You dont wanna mess with the anti theft or wires unless u really know what your doing

i dont have my door key or my key fab for my 1996 nissan maxima. my alarm has been triggered. how do i start my car?

try to put the key in the ingnition and turn it to the on possition and walk away for about 15 min come back turn it to off and see iff it starts

there is a chip inside your car key
some times gets damage or the car computer gets damage and no longer recognize your key chip
this causes the anti theft system to prevent the fuel injectors to open and the engine will not start because has no gas.

the security light stain on is your hint of what is going on.

I had the same problem on a 99 Nissan Maxima but i got the car running again what you need to do is replace the engine computer and then call a locksmith to reprogram your key to be recognize by the new computer i when to a lot of pain and suffer to get this solve.

before changing any thing make sure the plastic part of the key is not broken, if it is call your locksmith to make you a new one before changing any thing.

NOTE do not use a computer from a salvage yard unless you get to see the actual car it came from

if it came from a car than has the body in one piece do not buy it

its real hard to diagnose this problem and

chances are it came there because of the same problem you have.

if the car looks like it was in a crash the computer is more likely to be good.

but its always best to get it rebuild or brand new if you can.
after you change the computer call the locksmith to get you car key reprogram.

Do not use a computer from a 98 or 2000 because they will not work no mater what the salvage yard tells you they are to make money not to help you so it has to be 99 only.

If you use the drivers outside door lock to unlock the vehicle it should disarm the vehicle. emmissionwiz is correct, you can't simply shut the factory alarm off.

yes
u have to reset it get a new controler
