The security system can't be bypassed, it is integrated into the electronics of the engine control module. You will need the dealer to scan the systems control module and find out what is triggering the system to lock you out.

SOURCE: My Nissan 200 SX wont start

the only way to bypass the immobalizer if it is that is to open either the driver door or the boot with the key.
other wise you have to remove the immobalizer and fit an aftermarket one.

SOURCE: diesel engine wont start will

i had this problem and again it was narrowed down to the immobiliser. however it wasnt exactly the immobiliser it was the immobiliser coil. it sits around the key slot and it is the radio part that check the chip inside the key. got mine replaced and it starts first time every time now. it cost £35 to replace.

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.

SOURCE: immobilizer

If there is a blinking car icon with an "X" over it. This icon means the Immobilizer has been activated and hence won't allow the car to start. It could be due to a bad SCU, Start Control Unit. The SCU is actually the ignition switch on these cars.
Most of the time it's triggered by the anti-theft system..You can try this trick i learned that the dealers won't tell you...try locking and unlocking of the doors five times with the remote to reset the immobilizer and see if this helps.
Good luck..i hope this helps...please take a minute to rate me a fixya.

I need to bypass my immobilizer on my 1999 Grand Cherokee laredo


if you have a valid key (one that will start the car). buy a bypass module for your make n model (ebay n sutch places)

without a valid key you would have to get a dealer to program one for you. then get a bypass module suitable for your car(mimics the keys transponder code)

the whole point of the immobilizer is to prevent someone from using your car without a valid key. if it were as easy as cutting a wire or splicing some together it would be useless

I need to deactivate the immobilizer on my car


There is a small switch that activates/deactivates the anti theft security feature on your car. It is located near the hood release. Flip the switch off. Try to start. This should reset. The security system is activated inadvertently by locking and unlocking the doors. If the correct series is not followed the system will be armed and silent, often resulting in a dead battery.. no fun! I went through the same problem for a month before I found the solution- jump starting the car will also bypass the system, however it's not the ideal long term solution :)

Immobiliser activated


Charge the vattery and wait for the immobilizer system to "time out" (may take about 30 minutes). At that time, it will start if you are using the correct key for the vehicle.

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 need a 1998 mazda 323 ba immobiliser bypass key or another solution to start my car. Can anyone help me?


    I know this question is old but I recently encountered a similar problem with my 1995 323 BA and this may help someone else. Override the immobilizer by doing the following:


    open the car via the drivers door
    put the key in the ignition
    turn the key to ACC
    now turn the key to ON
    repeat the last 2 steps X 12 quickly (ignore the indicators flashing and the central locking activating).
    the dashboard should be lighting up as normal.
    Now turn the key to START

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