    Default Renault Laguna ii 2002 V6 Immobiliser

    Went to town tonight to go to a radio club tech night. As I was getting towards the empty end of the fuel tank I thought I would fill up on the way.

    So the story goes like this:

    Pull into the servo next to the usual fuel pump.

    Press the start/stop button and leave the key/card in its slot.

    Get out fill car with fuel, grab shopper docket from car and go pay for fuel.

    Get back into the car and push the start button and no go.

    I notice in the dash that the immobiliser light is flashing at a fast rate.

    The problem is exactly what is in this YouTube video https://www.youtube.com/watch?v=47tyOwMbexM

    So I try locking, unlocking open door, close door just like the video above but still no go.

    I decided to remove my card reader from the dash and dismantle it to see if there was anything obviously wrong with it. These have two little switches in them that are operated as you push the car in. These seem to be ok and the mechanisms operating them were also fine.

    I rang a mate that only lives a few blocks from this servo as he happens to have a Laguna as well to borrow his card reader as something easy to try and see if this works. So walk to his house and remove the card reader from his Laguna and then walk back to my car and try the card reader, still no go.

    After realising that this is getting me nowhere, I decide to move the car. So I thumble around at the base of the gear stick to release the car from park so that I can move the car out of the way. I can only move in a straight line because the steering is locked.

    With the car out of the way I took back the card reader that I had borrowed, and had a coffee and a chat about life and cars in general with my mate. While doing this I did a little bit of Googling about my dilemma. There was not a lot I could find other than about re-programming keys etc. But I did come across a you tube video or two about a similar problem in a Clio and a Traffic. They guy suggested disconnecting the battery for five minutes and reconnecting the battery. Then put the card in the slot and you should be able to start the engine.

    https://www.youtube.com/watch?v=WlsaZtsCzTU

    I had thought about doing this before I seen that video, but sort of dismissed it as I thought that it would not achieve anything. I discussed it with my mate while we were finishing our coffees. After a ten minute discussion we decide that there was nothing to loose by doing this and decided to grab a 10mm spanner and go back to the car. I showed what the car was doing before we disconnected the battery. So up came the bonnet and we disconnected the negative terminal waited for five minutes and then reconnected the battery terminal.

    I then slotted the card into its slot and lo and behold on come the dash lights, I pushed the start button and the car fired into life.

    Dropped my mated back at his house and gave the car a restart and in behaved like it should do.

    I then drove home, when I got home I again restarted the car without any problems.

    I'm not sure what caused this problem and probably never will, but it got me thinking about making up a small tool kit to fix these little problems. At present I don't carry any tools in this car. I have a set of jumper leads after a battery/alternator issue about 8 months ago.

    So far I have thought that I need to carry a 3/8 drive extension and a tommy bar (or similar) the auxiliary belt tensioner, a 10mm spanner for the battery. Maybe I should also carry enough tools to change the spark plugs and coil packs as well.

    Well sorted.
    You could always join the RACQ, NRMA, RACV or whatever the Tasmanian version is called and use their tools.

    If they actually carry anything much these days. If it isn't the battery, no fuel, or a spare tyre that needs to be changed they call a tow truck, and in some cases even that costs you.

    I use to be a member of the RACT many years ago and decided that as I was not using the brake down service decided not to renew my membership, that must of been about 25 years ago now.

    The few problems that I have had in that time I have been able to sort out myself on the side of the road.

    When I was using the Renault 12's as daily drivers I use to carry a small tool kit and a few consumables.

    When I started to get into the Lagunas I carried spare auxiliary belts but no tools to change them which in hind sight is probably not a smart move. The premise for this was that there is not much you can do to fix a modern car on the side of the road.

    Normal cover is useless in country areas, particularly TAS, however their ultimate cover has saved me a few times. I highly recommend their ultimate cover, which even covers you as a passenger! In Tas RACTV doesn't have km limits for ultimate cover, so you can recover your car from interstate (not covering the ferry).

    I had a Laguna II fuel problem that also required a windows style reboot of the computer when I forgot I need 91+ fuel. Limp mode.. battery off for 5 mins.. off we go for another 50km.

    I have the same Laguna - 2002 V6 Privilege LX

    Immobiliser plays up all the time. Can go weeks or months without trouble, and then have a spate of issues. Re-insert key, lock and unlock doors, open doors - all seems just superstitious responding. Sometimes it comes good after just one or two tries. Worst case it has been 10 minutes of locking and unlocking before it came good again. Has never not come good at some point ---- yet!

    You can get a code from Renault that you enter via the computer stalk on the steering wheel, or you can get an 'emulator' chip off e-bay, but it needs to be soldered in to the computer board and will permanently disable the immobiliser.

    I tried the locking/unlocking but still would not allow me to start the car, lost count of how many times I tried.

    Icon14 Great video. some really good information to know Col.

    Col thanks for posting that, I am hesitating about tempting fate, in even mentioning that I have heard of this fault with the card reader and did read how to roughly fix it in a jerrybuilt fashion, but not as good as that video showed and touch wood my Laguna has never suffered the same fault. though I do know that the reader fitted to my car is faulty in that the last time I had a new card programmed for the Laguna about 5 years ago they told me that my card reader was faulty and that they had to use a spare reader from another car to get through the re-programming sequence so have been expecting trouble at some time

    Have been thinking that I need to call in at King Street and see if Dave Cavanagh has a good spare to carry in the car as that usually ensures trouble free travel and also something to pull apart and see how the mechanism works while it is still operating, but then it is aging and probably is due for replacement 318,527km at the last transmission service in February, but it is handy with its towing ability and as a back up to the Diesel Megane.


    So thanks for posting that comprehensive video.

    Hope Murphys law doesn't bring on the same fault for me! I hope you get the same joy out of driving your Laguna as I have had over all these years.


    PS with any lectrical fault my usual first try is the disconnect the battery to get the gremlins out of the system, and mostly it worked...

    I don't think it was the card reader that was faulty as I had swapped it with a known good one.

    The only problem that I have had with the card reader in the past is a little piece of plastic that actuates the first switch as you push in the card. This is a known fault and is easy to rectify. The symptoms are when you push in the card the into the reader the first switch turns on the power for the car and if this does not happen the little plastic bit is broken. Also the other symptom is that you will have to hold your finger on the start button to start the car. Usually you just need to press the button then release and the car goes through its start procedure.

    What I did to fix this problem was to use some car bog and stick the piece of plastic back in place, this re-enforced the joint while still leaving the small plastic piece flexible to actuate the switch.
