HOW TO remove black immobiliser box(non keypad models only)
 

a breif guide on how to remove the black immobiliser box on non keypad models so if you dont have the keypad this IS for you

ENGINE MUST BE RUNNING WHILST REMOVING BLACK BOX!!!!!!!!!!
IF THE ENGINE IS NOT RUNNING IT WILL LOCK YOUR ECU!!

1.locate the black box but dont remove it yet which is located in the passenger footwell behind the fuse box it will look like this:


2.start engine and leave to tick over
3.with the engine running remove the black box there is a plastic clip which i just prised it off with a small flat head screw driver and let engine carry on running for 5 mins
4.switch off engine then switch back on and job done

Good stuff sam ! :)

also just to add the there is a plastic clip which levers down to release the box, i was there for like half an hour tryign to figure out how to dissconnect it and in the end i just cut it off lol, it was only after i took it off i realised how to take it off properly

i just prised it off with a small flat head screw driver

i did exactly the same thing, did take me a while to locate mine.

engine doesnt need to be running. ignition just needs to be on.

What if ecu already locked??? And u cannot start car would this unlock ecu???

my immobiliser light was flashing and car would not start and i ran a ignition feed to the feul pump from the stereing collum and it started then i took off my immobiliser and job done

What are the benefits of doing this?

So doing this removes the immobiliser completely? I.E. no need for little plastic fob key?

It just de activates the imobilizer so you can use another ecu. the fob only unlocks the doors so will still need it

Worth noting that you leave the box disconnected forever and if you are removing the engine to put in a donor car make sure the black box / keypad is removed BEFORE connecting the engine up.

This method works fine but soon as you connect up a transponder box or keypad it reverts back to its locked state!

I didn't mean the central looking fob, I meant the Immobiliser fob that fits the little plug under the steering wheel

The plug on that little black box, the wires coming from it are two of them grey or only one?

ignition feed
 

hi m8 i have the same prob i put my engine in a new shell and now wont start yellow key light on dash flashing i started getting fed up with it now and i seen your feed and seems you had same prob how do i run the ignition feed could you plz explaine so i can try it on mine please many thanks chris

If I remove the immobilizer box as above, I guess I can cut all the associated wiring out of the loom too?

yup if you really wanted to.

I really want to :)

Same principle for keypad cars... Only you unplug the keypad with the engine running :)

no need to have it running, just ignition on.

If you remove this box does that mean you don't need a new key coding?

Hi, new to the forum, been using it for a while and found some of the topics helpful, I have a Y Reg 2001 VTR 3 Plug ECU and have bought a VTS engine as I want to do a VTS conversion. The engine came with wiring loom, another small 3 plug ECU (Looks the same as my current VTR one) transponder box and ignition barrel with key. Will this be a straightforward swap?
And how would I go about removing my current engine / ECU immobiliser? Will it be any different coz I have a TOAD alarm / immobiliser fitted? Cheers

Anybody?? Bump :)

Ohhhh!! crap!!!
 

i undone this box the other day to see what it was & the engine n ignition wernt on! i cant start the car at the moment as ive got everything out ov the car ie dash etc. will my car start when i put the dash back together even tho i unplugged n replugged that box?:panic:

4got to mention that all the dash is out etc & most ov the engine bay wiring adapters are not connected ,rocker is off, hoses are off, radiator n fan is off & out , manifold is off & inlet man + injectors/housing,throttle body & air filterbox etc is out,thermostat & temp sensor is off too. had to replace the heater matrix as you can guess lol which ment i might as well replace the water pump, oil seals,timing belt n alterator belt, tentioner. lovely job done!!! for a novice .well will the car start although i unplugged n replugged that black box when i get the car back together? if it dont start what will i need to do? any ideas?

Does the engine need to be running or not? My imobiliser light is rapid flashing and also getting a rapid clicking sound. Had a problem with my fuel relay a couple weeks ago, brother in law smacked my relay and set my imobiliser light flashing.

Hi guys sorry to bring up old thread but I've got saxo with immobiliser key flashing I've previously read somewhere there's way to get car to start to disconnect the immobiliser box does anyone have information on this please?

wont help you only works on running cars, try getting a new pickup ring for the ignition barrel

Hi i can not find my immobilizer box. I have looked 4 hours now, EVERY WHERE inside the car, its a 1,6 16v vts 2001. Can the car have immobilizer, but not the immobilizer box in the car? Pls help
