Big problem and the Key Light on the Dash keeps Flashing at me! Help! :O

4th July 2011, 15:09

Hiya as above the car was working fine on Saturday and then Sunday it wouldnt start and the (Electronic immobiliser ignition key light) that is says in the Hand Book keeps flashing at me :\
Im having a guy come out tonight to have alook at it that can maybe sort it out instead of me going to the citroen dealer.
But i just want to double check on here what all you guys think. As if its something that is simple to sort out myself i would like to know please.

Many thanks x

Has your immobiliser chip fallen out of your key? Have you dropt your key lateley or broke the case? Mine did this and was due to the above.

4th July 2011, 15:33

As far as im aware it hasnt and i dont think iv dropped it or anything like that recently. So thats why im very confussed why its done this. Also i dont know if this info helps but when i tried to start it, the engine was ticking over but just not starting! Is this a normal sign?

4th July 2011, 15:34

Yeah, it's what happens when the immobiliser kicks in.

4th July 2011, 15:39

Ok that little worry is over then. Also my other problem is i dont have the master key as when i brought it only came with 1 key. And i dont have the card thats meant to have the keycode on it either

Im getting the feeling that im screwed! and might end up paying out alot of money just to get this problem sorted. :'(

as far as im aware if u call a citreon dealer or go into one they cand get the code for u. but you may have to pay for it???

before you ring citroen try giving the barrel a little tap it could be the pick-up ring at fault.

My old car had this problem, can get it started by turning on the ignition then disconnecting the battery then re-connecting it, then it should fire, not ideal having to lift the bonnet every time to start the car but at least you can get to places!

Ok thank you guys for your help but bigger problems have come up! The guy came round lastnight and plugged the car into his reader thing. He also had what the Citroen Dealers use aswel, as he works for the Police.
He is saying that there is nothing wrong with my key or the immobiliser on my car. The car is saying that there is no problem with it.
He called another guy up that said its my ECU thats got the problem. And its a commen fault in saxos. So the police guy took my ECU and is going to see what the problem is today with it.
Does this sound about right???????

FUCKING LOL!
works for the police, therfor he has a dealer diagnostic machine?! WTF seriously.
took your ECU..and done a runner tbh.

im a mechanic, therfore i also own the local brothel and whore market.

not being funny, but i will put it down to the pick up ring being faulty, which is 16quid from citroen, and they keep them on the shelf. as they are that common to go.
i ended up making my own... but for the sake of a few quid, get a new one, plug it in and sorted.

Really is it that simply? As i really dont have a clue when it comes to something like this. In all fairness i have no idea if the ECU is the problem. I have no Idea what the problem is!!!

lol

it could be possible to have a fault with the ECU... if there was, his diag equipment wouldnt be able to read the ECU to even tell you that (unless he has some seriously expensive gear, mine which is about 3.5grands worth wouldnt pick it up, btu the stuff in work around 15grands would)...but the chances of the ECU being at fault, is slim.
but also, if the engine management light isnt on, the computer wont pick it up, as that light being off, is like a lock to the fault codes.

the orange symbol on the dash means immob. it wont mean anything else.
so, the faults will be withing the Immob box, the Key or the transponder unit / pick up ring around the barrol.

behind the glove box / under the dash there will be a black box, about 3" square, disconect that, make sure the connections are clean, and put it back. see what that goes.
thats your immob box!

if it still does it, i will put it on to the pick up ring, which just slides over the ingnition barrol, and has a 2 pin connector. its a case of just discconecting it and sliding it off the barrol, and replacing it.

I guess when the guy brings back my ECU i can start checking what you have listed if the car still doesnt work.

Thanks

Im just still confussed how 1 day it works perfectly fine after me putting petrol in it and then the next day it just dont want to start. :\

5th July 2011, 15:06

i was thinking of another possiblilty, if it isnt the ecu thats the problem or other porblems that i can check that have been listed in this thread. Then could it be dodge fuel?

5th July 2011, 15:08

No, because your immobiliser light is on.

It's an immobiliser issue.

5th July 2011, 15:13

It was Just a thought as my friend has just told me that he had the same problem but with his 106 and he done the same thing as me, filled it up with petrol before it happened. And the key light kept flashing at him so he thought it was the immobiliser. But ended up finding out it was dodge fuel.

6th July 2011, 07:22

Ill repeat what everyone else is saying, it is an IMMOBILISER issue, sod all to do with your ECU. About every 10 times I start mine it will do the EXACT same as yours. I give the pickup ring (where you put your key in the ignition) a tap and turn ignition on/off a couple of times untill the immobiliser turns off, then start the car.

How many times did you fully turn off the ignition and back on again?

Get your ECU back NOW before the guy claims you owe him money for work he wont be doing. Your being taken for a right mate.

6th July 2011, 08:54

My car is the same, everytimne i go to start it the imob light flashes, i have to remove the key and try it again, it usually works after the 1st few attempts.

there is a way, of when its running, disconnecting the imob, and it wont have the problem again... but i cant find my imob, people say its in the passengers footwell... but i cant see it

6th July 2011, 09:21

In the passenger footwell, up behind the glovebox.

The immobiliser box is around there.

6th July 2011, 09:25

Ok the guy has tried my ecu on the car again yesterday night, as he re-mapped it to work without the immobilier. But it still didnt work.
So he has taken the ecu again to put it back to its original settings.
Iv ordered myself a new pick up ring from citroen and will get that saturday morning.
So when i get my ecu back tonight i will try all these things.

This guy is abit arrogant! as i said to him about what people on sax-p have been suggesting what the problem is. But he's adamant to say its my ecu. Only because every computer he plugs into it wont let him in to read what the problem is.

Seeing what he is now doing I say dont trust i guy who relys on a computer to give him anwser to whats wrong.

So im going to go to basic's and try what all guys all suggest. And i really hope it works !

Im just really confused as iv had the car for 3yrs and have never had this problem before. Is it just something that just happens? :\

I turned it a fair few times. But i didnt tap it and then turn. I will do all this straight away when i get my ecu back.

8th July 2011, 08:48

Iv changed the Pick Up Ring on my Saxo and still the immob Light is on my dash and the car will not start.

Any other suggestions?

iv done everything on here that people have said to do and still the car will not start!

Bump! Bump! Bump!
