My wife's 2002 Alpha Spider 2.0 TS has intermittent starting problems due to the key coded engine immobilizer. When this occurs, she leaves the car for 15-20 minutes and usually it will start. I have replaced the key batteries. Any help will be appreciated

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.

CHANGES OR MODIFICATIONS NOT EXPRESSLY APPROVED BY THE PARTY RESPONSIBLE FOR COMPLIANCE COULD VOID THE USER'S AUTHORITY TO OPERATE THE EQUIPMENT.




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.

First of all you need to programm all ignition keys using suitable diagnostic equipment (VAS, VAG-Com) connected to the data link connector of the car.

You have an electronic immobilizer key recognition problem. Now your key chip is not recognized by the transponder antenna fitted on the ignition switch barrel.

Everytime when you had a new key you must programm all available ignition car keys before trying to start the engine with this new key !!!

This warning lamp indicates that the engine is locked by the immobilizer system, and the engine start sequence must be repeat again.

From year 1995 in Audi-VW (VAG) cars is used engine immobilizer. The VAG group immobilizer system consists of an immobilizer ECU which controls the recognition of keys and the Engine Management ECU system. Immobilizer is activated when the ignition key is removed and, together with the engine control unit, largely prevents unauthorized starting of the engine. The system uses a transmitter and receiver unit in the ignition key (transponder). Whenever an attempt is made to start the engine, it transmits a new code to the car's electronics. The immobilizing is only cancelled and car motor electronic receives permission to start engine if the key sends a right authorization code.

You have an electronic immobilizer key recognition problem. Your key chip is not recognized by the transponder antenna fitted on the ignition switch barrel. Do you have this warning symbol lightning on the dashboard?

Use another ignition key that you have, and start the engine.

Dear Sir
It could be cause of 4 things 1 Key faulty 2 Engine Control Module 3 Ignition Immobilizer 4 Wiring.
But when you replacing immobilizer it should be program or paired with Engine Control Module and Key, Then only it will work, for programing you will require scanner or diagnostic tool for particular model, better to visit authorize workshop. if any doubts please feel free and ask me thanks.

PRESS THE UNLOCK BUTTON ON THE REMOTE FOR 30 SECS THEN TRY, IF IT DONT WORK PROPERLY,THEN YOU WILL HAVE TO TAKE IT TO A DEALER FOR DIAGNOSTIC(IF YOU CAN DO ANY WORK YOURSELF)OTHERWISE YOU WILL BE SEARCHING FOR THINGS YOU CANNOT SEE WITHOUT THE TOOLS.

extra the immobilizer

That's your immobilizer system light:
The Immobilizer System protects your car from theft. A properly coded master or valet key must be used in the ignition switch for the engine to start.
If an improperly coded key (or other device) is used, the engine’s fuel system is disabled.
When you turn the ignition switch to ON (II), the Immobilizer System indicator should come on for a few seconds, then go out. If the indicator starts to blink, it means the system does not recognize the coding of the key. Turn the ignition switch to LOCK (0), remove the key, reinsert it, and turn the switch to ON (II) again.
The system may not recognize your key’s coding if another immobilizer key or other metal object is near the ignition switch when you insert the key. To make sure the system recognizes the key code:
Do not keep other immobilizer keys on the same key ring.
Use a plastic or leather key fob, not metal.
Keep other keys away from your vehicle’s key and the ignition switch while trying to start the engine.
Do not attempt to alter this system or add other devices to it. Electrical problems could result that may make your car undriveable.
This indicator will also blink several times when you turn the ignition switch from ON (II) to ACCESSORY (I) or LOCK (0).
If the system repeatedly does not recognize the coding of your key, contact your Honda dealer.
If you have lost your key and you cannot start the engine, contact your Honda dealer.
Hope this lets you understand the light, and what should be happening.
