ann26

hi

i have a 03 laguna petrol car to day i stoped to get petrol when i went to go off my car would not start the imobiliser stayed on and would not come off i have 2 keys and tryes them boath althougt the imobliser light stayed on in the car the central locking was working fine

i caled brakedown assistance who boosted the car battry it went dead fron trying to start, and the car started no problem off i drove untill 10 mins later while driving the imobliser decided to cum on shutting off my car again tried 2 keys central locking working but imobliser light wont go off

called brake down assistance couldnt get it working so had to toe to renault garrage who informed me they had to run diognaustics on it which will be 150e than wot ever charge for problem

i rang a friend of mine who lives in the country and is a macanic tho retired explained to him the problem he said it is either the keys need re coading r their is a fault in the imobliser neds to be fixed
he than said if the keys r fine ask for the imobliser to be decoded and it will be fine i asked the garage to do this but they said it cannot be done

can any one shed any light r did the sane happen to their renault i am badley stuck as i nneed a car for school runs ect

Doesn't sound like a immobiliser to me as if the key wasn't coded or lost coding it wouldn't work at all my guess would be a faulty crank shaft sensor.if it is the immo I have the Renault clip which can recode the keys

ann26

is the crank shaft a big job?? so its prob the key?? how much is key to be coaded and where abouts ru???

thanks for reply

No more awkward than a normal key, you just dont put it in to a slot in the steering column and turn. Principal is the same.

The cards are known to go faulty more readily than a regular key though.

There was suppose to be alot of issues with the Laguna immobiliser system. The card was not making proper contact to disarm the system.

The buttons have a tendancy to break. The keys are quite thin so using a bit of force will break them more than a nice thick key. The old "press hard when the battery is low" will result in damage for instance. Leavign them in your back pocket is also not a good thing.

The basic system is similar to a key though. The reader (key card slot on the renault/ rign on the ignition with a standard key) gets the signal from the key when its close enough and ets the car start.

The fact that its a key card rather than a smaller fatter piece of plastic with a metal key blade sticking out is irrelevant.

Some keys are just not as reliable as others or more prone to damge from not being looked after.

The keys for a MkII Xantia for instance. When you hold the key to press the unlock button the pcb is sideways with the button pressing down along it. They break off over time. I'm very carefull with my cars and doubly so with my Xantia keys but I have to open and solder one of my keys again for the 2nd time in 4 years now cos its broken.

The first thing to do is get the keys and everything checked on the Renault clip.op I'm in Kildare if that suits
