    Default Nissan Micra Immobiliser Problems

    My father has an N reg Nissan Micra that has developed an imobiliser problem. When pressing the fob, it will sometimes turn off straight away, but other times can take 15-20 attempts to get it to switch off. We've been told its possible to disable the immobiliser by disconnecting the earth wire - anyone had any similar problems or possible solutions? The car is fine and runs well apart from this so would love to get it fixed for him.

    If this is a factory fit immobilser I would have thought it wouldn't be that easy to bypass-if you have another fob try this to prove if it is a fob/or car problem. If it proves to be a fob then the easiest thing would be to obtain a replacement fob.

    Thanks Sussex Patrol, he's tried the other fob but gets the same problem. It is a factory fitted immobiliser. Was looking for a way of not having to spend hundreds getting it reprogrammed. Are there any ways of bypassing it?

    It has an electronic immobiliser, there is no easy way to bypass it.

    Is it the NATS fob with the blue and red buttons or does it have 1 red button?

    As I and Mersey Patrol have said there will be no easy way of bypassing it-this would defeat the object of the immobilser. Also with this being a public forum we must be careful what we post in reference to security information.
    You could try a mobile locksmith/security specialist.
    Also check with Your Nissan dealer it may not be as expensive as you think.
    Also bear in mind that your car has an immobilser as standard and if this could be bypassed-this would affect your insurance.

    Just a thought have you replaced/checked that battery in the fob low batterys will give you trouble. The micra security system can be bypassed in about 45 minutes sorry can not tell you how with it been on open forum but any good autoelectricain should be able to do it.

    Thanks for your help everybody. It has one black button on the fob for the immobiliser and batteries have been changed. Do appreciate its not a secure area for anyone to give me a bypass solution, just wondered if it was possible.

    Will try and locate a nissan dealership.

    Cheers

    Default Immobiliser?

    I have had a similar problem in the last weeks. Once locked, after a while all lights would start flashing adn the battery would be dead in the morning.

    I took the car to a Nissan dealership in Coventry - advising them of problem - and after a 6-hours, 300 full service (P3), the problem came back - with the engine light still on.

    I am going back tomorrow, hoping they will be able to find out.

    I have a Nissan Micra K11, 1997, engine 1.3, 16 v. I have NATS 2, with a red chip. A friend broke my imobiliser. A new one is very expensive compared to the car price. What can I do? I bought an old one, with the same code on it, but the car didn't start. Now I will buy also the key with the red chip and the ECU (Engine control unit). If I change the entire system (key, immobliser, ECU) do I will succeed to start the car? Here in Romania (Baia Mare) the specialists from Nissan said that they cannot reset an old immobiliser to another car. It's that true? There have to be a solution to not buy a new one. I have to work two months to cover the price of a new one. It costs 400 euro.

    If you buy what is called a 'kit' this will get round it. You will need the engine ecu, immobiliser, key with chip in it, and the key reader which is the plastic ring round the ignition lock. Remove the chip from your key and fit the parts. If you tape the new key next to the ignition lock then you wont have to change the ignition lock. But you will not have an immobiliser function this way. If you need the immobiliser to work then you will have to change the igniton barrel then you can use the new key.
