Check the battery in the key as it may be flat.

You have to take it to the dealer to get the new key programmed. Try holding the old key near the ignition switch and see if it will start. That way at least you could drive it to the dealer instead of paying for a tow truck.

I have a service manual. I suppose you are talking about the anti-theft system. It says that if there is power going to the starter when you try and start that the anti-theft system is ok and that means that it is allow the car to start. If there is not power to the starter then your anti-theft system is stopping the car from starting for some reason.

SOURCE: I dont know where to hook up immobileizer bypass wire

An immobilizer bypass is an electrical circuit which allows current to flow to whatever component is starved of current to keep the engine from running (usually the coil). The immobilizer opens the circuit to the coil, the immobilizer bypass closes the circuit to the coil.

If you didn't install an immobilizer circuit, then you don't need the bypass. There are probably instructions you missed in the manual explaining the immobilizer circuit.

Replaced sterring colum now it wont start

S (Nissan Vehicle Immobilizer System-NATS) has the following immobilizer functions:  Since only NVIS (NATS) ignition keys, whose ID nos. have been registered into the ECM and IMMU of NVIS (NATS), allow the engine to run, operation of a stolen vehicle without a NVIS (NATS) registered key is prevented by NVIS (NATS). That is to say, NVIS (NATS) will immobilize the engine if someone tries to start it without the registered key of NVIS (NATS).  All of the originally supplied ignition key IDs have been NVIS (NATS) registered. If requested by the vehicle owner, a maximum of five key IDs can be registered into the NVIS (NATS) components.  The security indicator lamp blinks when the ignition switch is in "OFF" or "ACC" position. Therefore, NVIS (NATS) warns outsiders that the vehicle is equipped with the system.  When NVIS (NATS) detects trouble, the security indicator lamp lights up while ignition key is in the "ON" position.  NVIS (NATS) trouble diagnoses, system initialization and additional registration for other NVIS (NATS) ignition key IDs must be carried out using CONSULT-II hardware and CONSULT-II NVIS (NATS) software. Regarding the procedures for NVIS (NATS) initialization and NVIS (NATS) ignition key ID registration, refer to CONSULT-II OPERATION MANUAL IVIS/NVIS.  When servicing a malfunction of the NVIS (indicated by lighting up of Security Indicator Lamp) or registering another NVIS ignition key ID no., it is necessary to re-register original key identification. Therefore, be sure to receive ALL KEYS from vehicle owner. System Composition NIEL0174 The immobilizer function of the NVIS (NATS) consists of the following:  NVIS (NATS) ignition key  NVIS (NATS) immobilizer control unit (IMMU) located in the ignition key cylinder  ECM  Security indicator lamp.

How to disable anti theft system on 2003 Nissan Altima

This gets asked a lot, so I wrote a tip.

Want to bypass your vehicle security system?

The short answer is you can't!

All modern cars have alarms and immobilizers. There is a chip in the key and a chip in the ignition lock. If both are present, the ECM (engine control module) releases power to the ignition circuit. When you turn the key, the starter spins the engine and you get a spark. If any one of those three items are not in the chain, you get the engine to turn, but no spark. There is no way to beat the system.

The immobilizer is in place to stop exactly what you are trying to do, boost the car and drive it away..

Is there anyway to bypass the immobolizer on my 2002 Nissan Altima?

This is quite an easy problem haha. I am currently doing my remote start for the same car right now and I know that issue you are having. After 1 or two full failed attempts to start your car the ECU knows not to turn on because it is locked. You have to put the key in the key cylindericon1.png, turn it to the on position but don\'t start the car, then count to 5 and then turn off the car and pull out the key for 5 seconds. Do this for a total of 3 times and the system resets. As for getting rid of the immobilizer that will be unlikely due to the fact that it sends info to the ECU to authorize it to turn on the car. However, you can bypass it like I did and then you will be able to use remote start and all the other good stuff. There are 3 types of ways to bypass the immobilizer but it will cost from 30 to 50 bucks. I got this from a Nissan thread so thanks to: Originally Posted by Anymanstupid-immobilizer-prevents-my-altima-2000-start.html#post3665018">viewpost.gif

What does code p1610 mean

A P1610 Code has to do with the NATS system which is the security system in your car. If you look at your key there is a small blue square in it which contains a chip. This chip sends a signal to your immobilizer in your steering column and then to the Electric Control Module. If the ECM does not recognize the ID of the key then it will prevent it from starting.
Try resetting the ECM to get it to start and take it to the dealer. With luck all they have to do is re-program the keys to your ECM again. Worst case scenario, your ECM is toasted and you will need to get a new one. Good Luck!

2002 Altima cranks no start. Dealer said that the bcm ecm and immobilizer all need to be replaced. Had to come up witht he money so I had the car towed back to house. Now the dealer is saying that the dash...

Did your Check Engine or Service Engine Soon light come on? If so, did you read the code stored in the ECM? If so, what was (were) the code(s). It's unlikely that the ECM and BCM would both completely fail at the same time. More info please.

What is engine immobilizer

It's anti-theft security system, Nissan Vehicle Immobiliser System (NVIS)

The NISSAN Vehicle Immobilizer System will not allow the engine to start without the use of a registered key.

If the engine fails to start using a registered key (for example, when interference is caused by another registered key, an automated toll road device or automatic payment device on the key ring), restart the engine using the following procedures.

1. Leave the ignition switch placed in the ON position for approximately 5 seconds.

2. Place the ignition switch in the OFF or LOCK position and wait approximately 10 seconds.

3. Repeat steps 1 and 2.

4. Restart the engine while holding the device (which may have caused the interference) separate from the registered key.

If the no start condition re-occurs, NISSAN recommends placing the registered key on a separate key ring to avoid interference from other devices.

Statement related to Section 15 of FCC Rules for NISSAN Vehicle Immobilizer System (CONT ASSY - IMMOBILIZER, ANT ASSY - IMMOBILIZER) This device complies with part 15 of the FCC Rules and RSS-210 of Industry Canada. Operation is subject to the following two conditions; (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation of the device.


Security indicator light

For vehicles without Intelligent Key: This light blinks whenever the ignition switch is placed in the LOCK, OFF or ACC position.

For vehicles with Intelligent Key: This light blinks when the ignition switch is placed in the LOCK position with the key removed from the ignition switch.

This function indicates the NISSAN Vehicle Immobilizer System is operational.

If the NISSAN Vehicle Immobilizer System is malfunctioning, the light will remain on while the ignition switch is placed in the ON position.

If the light still remains on and/or the engine will not start, see a NISSAN dealer for NISSAN Vehicle Immobilizer System service as soon as possible. Please bring all registered keys that you have when visiting your NISSAN dealer for service.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

I replaced my battery in my 2006 nissan altima, car started right up, however the alarm set off and when the car started the battery light stayed on and also the brake light. There is no throttle either...

Hi Judy, sounds like your Altima has gone in to the secruity immobilzer mode. Your car thinks you are trying to steal it!
Depending on what factory system you have installed will determine how to remedy it...

Here is the basic relearn procedure---Lock & unlock your doors with the KEY.
1) Turn the key to the ON position and wait 15 seconds.

2) Turn the key to the OFF position and wait 30 seconds.

3) Repeat steps 1 & 2.

If problems still remains, follow the same procedure with the valet key or another key that is registered to that immobilizer system on the vehicle.
Also, check your owners manual---there should be more security advice in there.

I hope this helps...holler back if you need more assistance...
