Hi

I am hoping to put a car alarm and central locking on my car , to do this I need to bypass the NATS immobilser sytem that came with the car

I would like to know , how to bypass the ( Nissan anti theft system ) immobiliser on my 95 Nissan primera

I know there is an immobiliser box behind the glove box , but i need top get the wiring config. so i can by-pass it
Any information would be greatly appreciated.

is this a UK spec primera?? if so i may be able to help you out. Let me know. The NATS system can be bypassed fairly easily ive been told but you cant bypass the NATS 2 system.

hi there! I have similar problem in my nissan primera UK model 95 (M-Reg)
please tell me how to bypass the immobiliser!!!!

advance thanks

There are ways of bypaeeing the nats. First you need to know what noats syatem is fitted to your car.
nats 1 has the key fob (black with lock and unlock buttons)
nats 2 onwards will have a red or blue chip in the key by the key blade. (this syatem is very hard to bypass as it runs trough the ecu and control units)
on a micra K11 with nats 1, bepending on factory or accessory fitment, you can simply unplug the nats loom and control unit, and connect the origanal loom back in.

on a P10 primera, these where mostly factory fitted. again if you have the black fob with the 2 buttons, these can be bypassed quite easy. you will need to remove the glovebox and heater motor to gain exess to the nats control unit. ( located on the A pillar) when you disconnect the nats unit you will be left with the wiring loom connector. all you have to do is branch the coresponding wires with each other. and there you have disconected nats.

there was a adapter you could fit onto the loom when you had removed the nats control unit. dealers where surposed to return it to nissan as the adapter had a surcharge of £100.

i may have one laying around somewhere, i will look and see if i can upload a picture (if this forum lets pictures).

Any other nats system you will need to know electrics very well to bypass.

Hi again. To bypass the NATS system is not an easy job. if you feel you have the mechanical skills than i can tell you how to do it. You will need to remove the glovebox and the heater motor to gain exess to the nats immu (control unit). I have a bypass plug made up i can email you pictures so you know which wires you have to link to bypass the nats system. let me know.

Hi there,
My immobiliser has finally stopped working (i used to just press the key fob button over and over again - Nissan Primera '94). I took the advice on this thread and removed the blower motor but could not find the unit. I eventually found it under the ashtray at the base of the central fascia, or at least i found the only box that seems to fit the bill - disconecting it stops the immobiliser light blinking on the dash. It has 10 wires going into it and although i have tried somewhat random combinations, i have not managed to get the car to start. I was wondering if you could explain which wires should be connected together as your 1&2, 5&6, 7&8 doesn't work - besides which i have 10 wires. A description of which wires to connect either by colour markings or by their numbers on the plug that connects them to the control box would be really helpful! thanks!!!

if anyone including nissan tech who has the diagram to bypass nats 2 i would be much obliged as im now desperate.........can whoever is willing to help me send it via email please s_a_cassim@yahoo.co.uk

Hi, if u still have the pictures of the nat 1 bypass made can do please email to me?I asked for professional help an i was told that this goes together with control system an can not be bypasst.So i saw your article and decided to ask for help.I really wish you could help me.I have a primera 95 model P10.
