SOURCE: automatic engine immobilizer wo'nt reset

The immobilizer does not "lock" the ignition, it does not energize the fuel injection relay. What you have is a "locked" steering column. Put the key in the ignition, and pull/turn the steering wheel HARD left or right, whilst turning the key to on or start. Do BOTH at the same time.The action of you pulling on the steering wheel will unlock the steering column.

you really need the dealer for this one. car is too new and should be under warrenty. This should not of happen. Most likely you have a computer issue with codes stored that will direct the technician in fixing this.

After 5mins. reconnect the battery connector, turn the engine on and see how it goes. Hope this helps and thank you for using FixYa!

Hello cbmconstruct...i'm not allowed to call you in this chat forum, but i will do my best to help you here. I know how frustrating these security systems can be...another way for the dealers to make a buck...Do you have a blank master key? Should be a black one. Once these lights sets it no longer reckonizes your key or fob---The immboilizer is built in to the ECU.
Luckily for you they are resetable using a scan tool with the proper software. You should never have to replace the computer unless it it is destroyed. They can be reset to accept new keys (most dealers don't know this). Some can be done with scan tools, some require removal of the ECU or Immobilizer unit and can be reflashed to accept new keys....they get reflashed often for local dealers and auctions, this is a heck of alot cheaper than replacing the ECU at $1100+

I suggest getting in touch with a local locksmith (Must be an auto specialist) that has the required software. Or another option---Prices for a new master key run $40-$60, the programming for a master key would be $75-$95 depending on the dealership.

Good luck & i hope this helps.

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.

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.

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.

Vw beetle does not start. seems like its some kind of anti theft protection. the car/key icon lights up, it turns over for a second , then off. this is the first time this has happened, but we bought it...


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.

    I had a new key cut for my 2004 accord and replaced the keyless entry pad. The car will not start...does the pad need reprogramed to start the car


    If you car has the immobilizer system, the following might help.

    The Immobilizer System protects your car from theft. A properly coded ignition 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.

    Hope this is helpful to you.

    The key symbol appears


    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.
