key card

Postby KIB » Sun Dec 21, 2008 12:05 am

I have an 05 1.5 DCI Megane with key less entry, this problem started to be once in a while and has become a more regular fault. The doors will not lock or unlock as you approach, none of them. The boot seems to be fine opens when you touch the handle and locks and unlocks from the badge button. The doors, no go you have to now lock and unlock the car using the key card buttons. Once inside, the car will start withOUT putting the card in the reader. and finally when you get out you can sometimes lock the car from the boot badge. I've changed the battery in the key card as a matter of course, no differant. Any ideas anyone? Will this fault be stored within the ecu if i get the codes read?

i'm guessing one of the rear door sensors is bust which is the "master" sensor to the other doors... hence none of them work.

I would agree that 1 or more of the door infrared sensors have become defective.. Probably due to water ingress and this has diabled the handsfree opening system..

You need to have the system diagnosed to identify which of the sensors is defective as it could be any one of them..

The cost of 1 sensor is around £200 for the part only from your dealer. So will be a costly repair..

from what i remember of other posts, one of the rear ones acts as a master or something and perhaps relays information.. if that goes, they all go.
sadly it sounds like you have 3 duff sensors.

in the wet, my drivers side rear door doesn't lock (not sure if it unlocks via sensors) but the rest do. once it's dry they all work fine.

it could be the buttons, if they are stuck then the hands free dosnt work on those doors, when my went and got it done under warranty (with a fight), this is what they had to replace on mine....

the main culprit is jet washing...

i`ve renewed the buttons,as i fitted complete brand new handles.was no different.luckily i got them very cheap :D

i think i`ll have to leave it as it is. don`t think it warrants £200 per sensor just to save me taking the card out of my pocket :eek

Thanks for that.

I have also noticed that with this cold a damp weather it dosen't work, weather warms up abit and some times it works.

It will have to wait for now and hopfully in the summer it will work and I'll probably get rid as there are all sorts of gremlins appearing, creaky dash, creaky rear suspension, dash bulbs blowing, noisey wipers.the list goes on my wallet can't keep up at the moment.
