Is is my Immobiliser????



  182 Sport
I need some advice..... My 2005 182 is getting very tempramental on these cold mornings.
The engine turns over but it just wont start. I end up having to get out of the car and locking then opening it a couple of times until I hear the alarm reset itself, then it will start - but this morning it took me 7 attemts at resetting the alarm!!!! It only happens in the morning when its cold. I have been told it could be my immobiliser or the key.
I have owned the car since new and have never had the battery in the key replaced so I decided to use the spare key (even though its sat in the drawer for 5 yrs) but its gradually getting worse. Ive only done 28k miles so it does not really get a good run as I only do max 3 - 4 miles a day during the week.
Is it the car battery itself as this is also the original one? :(

Please any advice would help as I really dont want to line my local Renault dealers pockets just before Xmas. :S

what do you mean by resetting the alarm? does it go off? Alarm hasn't got anything to do with the immobiliser really. When it's cranking, does it seem to get weaker? If so it could be the car battery. I would try changing the keys batteries first though. If it continually cranks, but nothing happens it could be the crank sensor also. You're not too far from JMS are you, its in Uxbridge? Might be worth popping in?

Sorry for the confusion - I meant resetting with the key by way of locking/unlocking the car. No the alarm doesnt keep going off. The car cranks over fine, it does not get slower whilst turning over, so maybe its not the battery then?

if it cranks fine, and there is no immobiliser light issues when you're cranking, then i'd say it was the crank sensor. Get it stuck on diagnostics to be sure (you don't have to go to renault though), or get someone to remove it and clean it.

Thanks Jonny, Ive checked the lightsand they seem to be behaving themselves and Ive had the battery replaced in the key on your advice.

It started fine this morning, but Ive just been out to lunch and it took 4 attempts of locking/opening - hearing the high pitched beep twice to reset itself until it started!!

Thinking back to the summer....... I had the cam belt replaced & had it serviced with Renalt. I took it back to Renault twice in the 10 days after because I had problems starting it. They carried out all kinds of checks on it (supposedly) and could not find a fault with it. Granted it was starting more often than not and even one of the Technicians took it home and it never did it whilst in their possession (typical).

Do you still think it could be the crank sensor?

Mine does a similiar thing. Started it to clear the ice off the screen etc. Noticed when it started, the engine was running for about 0.5 seconds before rev. counter or petrol gauge moved. Turned it off and went back inside. Went back out, started fine and parked it on the road. Next time I tried to start it it wouldn't work. Turns over about four times and then stops you cranking it over and you just get a clicking noise from behind the dash. RAC came and couldn't fix it, but I had them fit a crankshaft sensor. Got it towed to local garage. Garage got it to work as follows:

1. Turn ignition on to the second click and leave the car door open so you don't get locked out.
2. Disconnect the battery. (8mm spanner on negative terminal)
3. Wait for 2 or 3 mins.
4. Re-Connect battery.
5. Turn the key off and remove.
6. Get out, shut the door and lock the car.
7. Un-lock the car and try to start it.

This worked first time. It seems to reset the immobiliser or something but cars going great now. Also, the changing of the crankshaft sensor seems to have stopped the "engine running before rev. counter situation".

Hope this works with yours ;)

P.S you might want to make sure the battery's well charged if you've been trying to start it loads of times.
