Immobiliser

:banghead:

I've had problems with my immobiliser and this weekend it decided to completly pack in. I was in a car park and the immobilser would not disarm.

Its now been towed to the dealer, and I'm expecting sky high costs of repair. I find it quite strange that there appears to be many people who have experienced similar problems yet Renault have not done anything about this.

Do you think we should do something about this?

I have had an Intermittant problem with my 1999 Laguna too. I changed the Batteries in the key etc, I found that by disconnecting the Battery positive lead whilst leaving the key in the ignition for one minute, then reconnecting the lead securely, then removing the key from the ignition and locking the car using the key and leaving the car for 2 hours sorted the problem for me. I have been told that this problem is a common occurance and is either the fault with the Key chip being out of sequence with the immobiliser, or a fault with the recieving ring on the Steering lock. If its the key, Renault quoted me £120 + VAT and a 12 day wait for the new key to be delivered from France, then the key has to be re-coded at the Main Dealer. If its the ring, then its between £40 - £60 plus VAT and a 12 day wait for the ring to be delivered from France then It has to be Syncro'd to your key chip and Immobiliser. Point to note though is that I found it worked for me - it may be you have a different problem and it may not work for you, either way - before considering removal of the Battery lead - make sure you have your stereo code!!! Hope you have some luck.

Personally, I think that we need to get a group of us together who are having this problem and as a group, contact trading standards. If this is a known fault through some kind of faulty equipment, Renault should be fixing it at their own expense, not ours. And all those who have had this done should be re-imbursed.

RENAULT DID SOMETHING ABOUT IT ABOUT 3 YRS AGO IF YOU COMPLAINED ABOUT THE KEYS NOT WOKING WHEN IT YOU TOOK THE CAR IN FOR SERVICE THEN THE KEY WOULD HAVE BEEN CHANGED DIDNT TAKE IT TO THE DEALERS FOR SERVICEING ... WHOSE FAULTS THAT RENAULTS

I have just had a problem with my 1994 Laguna ommobilser locking on. This problem was caused by water getting through the aerial point leaking. Water has gotten onto the receiver printed circuit board which I understand is a common fault with Laguna and Megane models. My fix was to get a replacement second hand receiver board which cost me 10 pounds. I instaled it this morning and it worked. It seems that not many people know where the 4 digit securuity code for the immobilser is stored. Some people think it is in the key fob, others in the receiver circuit board located in the overhead panel. It is in fact located in the ECU under the cars bonnet.

Changing thereceiver circuit board does not lose the code so there is no need to recode anything. This should be your firt option before taking your car to a Renault dealer which will cost you loads of money. Don't forget to get a tube of silicone sealant and seal the aeriel point on the roof of the car as well to prevent further leakin.

Quite a simple fix, takes a couple of minutes. The front panel on the overhead console with the internal lights on just slides forward and reveals this circuit board. Try this before anything else and you may save yourself a lot of money and anguish.

My car ahs been immobilised all this week until I received the replacement circuit board this morning.

Let me know how you get on as I have seen all sorts of theories about getting code numbers and all tha sort of stuff.

Maybe I was just lucky but it would have to be something really big for the ECU to pack up and you you do have an expensive problem.

When Renault cars were sold the buyers should of had a scratch card with a 4 digit number. But Renault have kept these cards from the public. I can only presume it's because then we are at the mercy of Renault. I have just got my number from them after telling them I will prosicute them for holding back this code. Just take your logbook & maybe key code you can found this on the back of the circuit in the key. This 4 digit number will disable the Immobiliser.

When I asked for the code the Renault staff insisted it was illegal for them to provide me with the code!!

Had I owned the vehicle at the time it would've been mine so check your facts before you flame. And check your spelling before you post if you're going to be a clever dick.

I don't know whether is of any interest. I had a problem with my immobiliser: nothing - nothing would get it to start. Then I disconnected the battery for 1 hour - reconnected it and hey presto.

I'm just curious with this one so bear with me.

A few years ago here in Birmingham, there was an issue with the Immobilisers on most Renaults in that there was a newly built shopping centre in Solihull and if you were in the car park, your immobiliser would not disarm. Not sure how this was rectified (I didn't have a problem with my 1997 Laguna in that car park so I think it probably effected newer cars). The reason I'm saying this is because your car packed up in a car park so maybe there is a similar problem more to do with that location. As crazy as it sounds, it is true about this shopping centre (ironically called Touchwood!)

:nono: you dont wanna go to main dealer lol
i work for blue hawk electronics and we come across with alot of immobaliser probs on the reanult clio/megane & laguna's but what we can do is decode the actual siemens E.C.U (engine control unit) which does away with the immobaliser all together let me know if you need any help
Regards Dennis @ Blue Hawk Electronics

We are able to Decode the E.C.U control Units which does away with the immabaliser all we need is the part number of the E.C.U and we'll let you know if its possible please contact us on 07773289170 / 07966684240 / 01159539077 mon-fri (9am-5pm)

hi i,m having the non start problem on a laguna, took it to renault in liverpool and after a two hour deep diagnosis they tell me i need an ecu, key controller and keys plus re-programming, total cost £1050! as if! its a p reg car for god sake, the annoying part is i was told £85 pounds job done in the first place, then the bad attitude of the service reception manager saun voslo, and £180 to retrieve the car with no result! buy another renault?
over my dead body! from what i have gathered and going by another bypass i did the end result of these things is usually one live or one negative to the ecu being controlled on or off, so if anyone knows which wire it is please give us all a break. share share share and stuff renault

:banghead:I get a Vocal warning that the imobiliser is not working properly - does this mean that soon I want be able to start the car, if so, Why can't we just rip out the usless imobiliser and fit an after market item :evillol: does anyone know how to bypass the imobiliser, alarm and central locking controller ?

Is there any way we can rip the bl--dy immobiliser, cetral locking and alarm system out and replace the whole lot with a more usable, non malfunctional system - Does anyone know how best to tackle it?

Hi there, I work for Renault and have been interested by the uproar caused by the immobiliser systems. I can however understand frustration caused when the key no longer works.

There are two main types of immobiliser sytem, the infrared which can be identified by the small glass ball at the base of the black part of the key and the ultrasonic or radio type system. These differ in two ways. The first infrared system relies on the button on the key being pressed to deactivate the imobiliser. The second has a seperate chip and a decoder ring around the ignition barrell and even if the key does not operate the central locking should have no adverse effect on the car starting.

If you have the first system which is the earlier of the two and was phased out around 1998 a good way to check if the key is still operational (even if the red light comes on) is to point the key at a mobile phone camera and you should be able to see blue light coming from the glass ball on the key. If there is no light then the key is usually unsalvageable and would require replacement. If there is light coming out of the key yet it does not start the car it is most likely that the key and the car have gone 'out of sync' and will need to be 're-phased'. On anything other than a megane or scenic it requires the Renault Diagnostic computer to be connected to the vehicle before the key can be rephased.

Over-riding the imobiliser is possible but you will need the imobiliser code which contary to popular belief is avaliable from Renault dealers (usually about £10+vat). Renault UK have issued a document to dealers that authorise them to pass on this information provided you have shown photo id and the V5 registration document (The code is obtained from the chassis number). For a Laguna you will need to use the pedal and wiper stalk method of code entry and for a megane or scenic the code is entered via the central locking button. Immolbilser codes are not inside the key!! The number on the key together with the chassis number when entered into a crypted Renault database then produce an immobiliser code.

If you have the later radio type key there are no 'cheats' to over-ride the system and a diagnostic routine will be the way to go. You could guess and replace coded ring around the steering lock but these rarely give trouble and are often incorrectly diagnosed as the fault.

There is not a design fault with these systems, perphaps what is more of a problem is that inside your key is delicate circuitry that is unfortunatley often over delicate and anything such as magnets, heat, cold, dropping the key or sitting on it could have an adverse effect on it. As such my advice to you all would be to treat your key like gold dust as in 90% of cases the key is the problem rather than the car itself.

I hope this provides some answers and whilst i'm not strictly defending Renault I hope it provides a view from the other side of the fence. By the way an honest and reputable dealer should not charge you more than half an hour's labour to 're-phase' the key and again if you are replacing the key (which is about £70+vat) the labour charge should not be more than half an hour (definately less then £50inc vat).

(1996 RENAULT LAGUNA) I had a problem with the immobiliser :banghead: I purchased the code from A Renault Dealer for which i was charged £10 plus V.A.T
I put the code in using the throttle and the winscreen wiper stick. You press the throttle fully to the floor until the lights go out, enter the first code number then release the throttle and repeat for the rest of the code, this overrides the immobiliser and unfortunatly you have to lock the car manualy which i can put up with. Hope this might help someone else.:grinyes:

Hello All,

Just in case it works for anyone else:

I went in to my local Renault dealer with all guns blazing, gave them my Laguna Chassis No. and the number on the PCB inside the key. They gave me the code to turn off the immobiliser.

The interesting thing was that they said that if that didn't work, to try this code: 1232

Now that looks like a generic code to me. One which is easy to remember and quick to input using the pedal and button method.

If this works for you, please pass it on. It worked for me!

Cheers,

Ronan

I can now calculate your immobilisor 4 digit bypass code if your key has failed, this will enable you to continue to use your car until such time as your key has been recoded to your car. This system is guaranteed to work and I will only charge £10 for the service, your dealer will charge up to £30 and you have to go to the dealers with your proof of ID, I can do it online in minutes.

All you need to do is PM me with your car type, this is an identification number of the body type, eg. DAOH for a 96 - 2001 Coupe, and the last 5 digits of the code inside your key (chassis number or reg number not required), and send a payment via Paypal.

Hi,

I am just wondering if you can help me, I have a p reg Renault laguna 2.0 rt and I have just changed the radio unit and I have lost the central locking both ways from the key fob and the door lock and the fan now runs after the engine is off plus now since I left the car for a week the battery went nearly dead and now I cannot start the car as I think the immobliser has now locked the system??? Can you help please??

Thank you for your time, if you need any info please ask

Thank you in advance

Firstly we need to establish whether or not your car can have the imobilser bypassed, to test for this is simple, turn on your ignition and press the accellerator pedal to the floor and hold it there a few seconds, if the red light stops flashing rapidly and goes to a slow flash, it will work, try this and then get back to me.

hi, i have tryed what you said about the flashing light but no change, i took it renault and they have tryed to recode it...no change they now say maybe its the sensor near the light or the box on the floor i take it thats the ecu (computer?) at a cost of course!! any more suggestions and can i overide the immob? and keep the central locking via the key fob? if so thats what i want to do..then sell it.

thanks mark

I'm having this problem with my 1996 megane. I changed the main car battery after it went flat and the car started fine. The next day i realised the key remote was not working well so changed the batterys in it. The car still worked fine and used it for work the next day.

A day later, when I came to get in, I used the key to deactivate the central locking but nothing happened. The red light flashed on the key but I couldn't get in. I opened the door with the key but clicking the key still wouldnt have an effect on the immobiliser. I moved it right upto the black dome by the mirror and clicked, but got no response. The redlight on the key flashed but no response from the car.

The red flashing LED in the dash by the speedo still flashed and the car would turn over but not start.

I've tried everything I can think of but am lost.

I've searched the sites and can confirm that the key works as when I view the IR transmit LED from my camera phone it flashes twice in dark blue when the button is pressed.

I've read that taking the V5 and ID to the local Renault dealer will give me the immobiliser code. Will this permanently deactive the immobiliser or will I have to enter it each and everytime I want to start the car? They told me the code would cost £20 plus VAT.

Will I need to get the key resynced with the car or will the car now work fine? I guess I will need to use the key to enter the car.

Any help would be really appreciated as I am loath to give Renault any more money than I have to. :banghead:

Hi. I have a Renault Laguna 1.8 RT, M reg. I parked it outside the chip shop last night leaving my kids in the car with the radio on. When i cam back i went to start the car but the pr-ignition lights didn,t light up but the engine turned over obviously not starting. The electric windows and sunroof also dont work but everything else does. Is this an immobiliser problem and if so how do i fix it. Also fuel cut off has kicked in i take it as there is deffo no fuel getting to the engine when i turn it over.

If you need help with the immobiliser go here http://www.coupe-club.org.uk/smf/index.php/topic,143.0.html

there is a free site that you can get the code for your renault for FREE !!!!!!!!
after many hours of frustration and the thought of paying renault a fortune to give me the code for my renault i started searching the web if you type in your google search bar bba-reman emergancy recode it give give you the link directly to the site it might say you need the number off the ECU but the vin number will do and the code of your key found inside the key or on the front page of your service book you type the two codes in and press enter .it will give you a 4 digit number and the instructions of how to put it in and then how to recode your key

This works fine on my 1997 scenic (bba-reman)
I would recommend this way of getting your motor started
***£30-00 to a Renault dealer is about what is expected***
***£10-00 to an Auto Motive specialist for info that is freely available stinks of greed***

DON'T PAY OUT ANY MONEY TO THESE PEOPLE UNTIL YOU HAVE TRIED TO SORT IT YOURSELF FIRST!!!!!!!!!

hey, one day i tried to start my car as normal, but my renualt clio grande did not recognise the key. i brought it to the renualt dealer and i was told i needed re programme the key for £52 and if that didnt work then i would have a further investigation which would need to pay another £52. after all this i was told i need a new key. when i got the new key they told me that they could not reprogramme it and that there were a of problems with my immobliser. as far as i was concerned it had wrked before and now all of a sudden they said it wasnt. however, i was searching around a came up with this website called remote key ltd. i spoke to someone and he seemed really nice and actually knwe what he was talking about. i checked out there company yto see if it was registered and it was. so as a result im going to send the computer box off and see what happens. will keep you posted.

I have a Renault Laguna 1997 and could not start it because I could not disarm the immobiliser. I almost dispose of the car because of this.
I was reading this thread, and it triggered me to check the receiver; just behind the rear view mirror. The reveiver unit board had some "burn" marks so I went to the scrab-jard and bought one (Renault but not Laguna) for 5 Euro.

Replacing the board solved the problem. Good thing I did not mess with the other units.

Tip from me: try the simple things like this receiver unit befor replacing other stuff and spending money on other things.
