I have a 2.2 turbo diesel grand espace, year of manufacture is 2000(W).
ever since I have owned it, about 18 months now the remote central locking has refused to work.
All the other cars fuctions seem to work correctly but my local renault dealer wanted over 1000 to fix the problem.
I lock the car using the central locking button on the overhead console and the passenger door lock.
I have had the keys checked and the one we normally use is not emitting a signal.
I have purchased a new key fob off of Ebay but I have not had the courage to try and reset the keys using my old working key and the new one I purchased off of Ebay.
Can I align the two key codes or do I have to take them to my dealer?
I would be very grateful for any help you can offer.
regards
Ross

As far as I know you can only resync the keys which came with the car(but I may be wrong)

To resync keys follow this procedure


1. Switch off the ignition
2. Press the central locking button (either side) for more than two seconds. The doors will lock and unlock.
3. You now have 15 seconds to operate the plip twice within 3 seconds, pointing it at the IR Receiver. The doors will lock and unlock after the second press.
4. If you have a second plip, you need to the same with that one too, and all within the 15 seconds.

Not sure if it will work for you but try it and let us know how you get on

All the other cars functions seem to work correctly but my local renault dealer wanted over 1000 to fix the problem...

They must be joking!  What were they planning to do for that amount?  I really would like to know who they are and what they wanted to do, since I will take this up with Renault myself being an RTE.

I have had the keys checked and the one we normally use is not emitting a signal.

So why continue using that key then?  If it doesn't emit a signal it can never work the remote obviously.  However if the other key is emitting a signal, then simply re-sync it to the car.  You cannot do any damage or stop the key from working (starting the car) if it is working now.  So did you try re-synching the key as per Lennart's instructions and did it work?

How can you get a correct key from eBay?  Did they ask for the vehicle VIN and key code?  These are required to get a key plip that can be synchronised to your car.  Renault do not use a 'blank' plip that can be synchronised to any car with this particular Espace.  So I don't see how they can sell key plips that will work.

Can I align the two key codes or do I have to take them to my dealer?

If the key plip is the correct one for your chassis and immobiliser then you can re-sync it yourself with this particular vehicle, but Renault have many different systems and many do need dealer equipment and codes to re-configure new keys/plips/cards.

Hi Roy,

Many thanks for your comments on my remote central locking problem.

I have not used the system as described in the reply to my problem as it seemed to refer to the infra red type of central locking system as fitted to earlier models and not the radio type that I have in my espace.

Can I try to elaborate on the problem, as I am not an expert in electronics so my understanding of how the central locking system works is very basic.

When I bought the car, about 18 months ago the private seller said that the problem with the central locking was a dead battery in the key.

I replaced the battery and it of course made no difference, so I took the car to my nearest Renault main agent and they told me that "their computer wouldn't talk to my car computer" so they advised that I have all the elements replaced, computer - dashboard and keys and have the system reprogrammed, all for an estimated minimum cost of 1000.

As there were no other problems with the cars' electronics other that the remote central locking I declined to spend the money, and I have been locing the car as previously described ever since.

My local friendly Renault independant garage have checked both of my keys and this is how I found out that one was not emitting a signal, and as the second key had never been used I was told that the codes were more than likely out of synch.

This is why I bought the key off of Ebay thinking that the good key I had could be synchronised with the new key, but this does not seem to be the case.

If I was sure that the purchase of a new key from Renault, to match the good one I have, and then having them synchronised, would cure my problem I would get it done, but there seems to be no guarantee that this will work, and from my understanding the second of my keys cannot be used in my car without having 2 keys to re-synchronise.

I have been advised that having a new alarm system fitted, for about 300 would give me back the central locking facility, using the new alarm system plips.

I would prefer to stick with the Renault system in the car, but i cannot justify the expense, as quoted by my Renault main agent.

If you would like any more information or clarification just let me know.

Any help you can let me have would be much appreciated.

Many thanks.

Many thanks for your comments on my remote central locking problem.

I have not used the system as described in the reply to my problem as it seemed to refer to the infra red type of central locking system as fitted to earlier models and not the radio type that I have in my espace.

I can understand your doubts Ross but the system is virtually the same as it happens.  The main difference is that you only need to press your plip once where an infra-red plip has to be pressed several times, for each good plip, whilst aiming the infra-red correctly.

The pick up for the remote is combined in the electronic dash panel on your car.  The keys contain two systems, one for unlocking/locking the doors by remote (ultra sonic radio frequency) and a chip that the immobiliser system uses to protect the starting.  When you press the plip it emits a signal which is picked up by the dash and if correct the central locking is operated.  However, whether or not this works, the starting is a separate system entirely, as you know since your car will start.  The chip in the key is 'read' by a reader ring around the ignition switch, so when you put the key in and turn on the code is read, passed to the immobiliser and provided it is correct, the system is unlocked and the engine is authorised to start.

Now the radio key signal for opening the doors, is on a rolling code system.  So every time you press it the code changes.  This is to stop anyone with a radio reader nearby from simply reading the code, and then once you have gone, using that code to open the vehicle. (this was possible on very early non-Renault systems with a fixed code).  One fact of this rolling code system which is not properly explained to owners, is that you must use both keys frequently.  It doesn't matter if you don't use one of them for say a week or two but eventually if it is not used for a long time, the one that is not being used will get so far out of sync. with the rolling (changing) code, that it can no longer work.  As long as they are both used they both stay in sync.  If or when one key does get out of sync. it is fairly simple normally to re-sync. it and then it will work again.

So in all likelihood you just need to synchronise the key that is transmitting and then use that one to open the doors and start the vehicle, and keep the second one as a backup that will at least start the car even though it cannot transmit and therefore work the doors.

I am right in assuming that the good key/plip i.e. the one that will transmit a signal, does start and run the car?  Because if it doesn't you probably do have a serious problem.  So can you first confirm please that both keys can be used to start the car now.

That might have explained the reason for one key not plip locking but what about the second?  It would be unlikely that both keys go flat at the same time!

Replacing a complete system is only necessary if you have lost both keys.  That is not the case here.  So whilst there may be a problem preventing their computer interfacing with the car computer, I don't rule out that they have simply not done their job properly at this stage.

The first job should have been to synchronise the keys or in your case the one key that is working.  For that they don't need the computers to interface.

So as long as the key that transmits does actually start the car already, proving it is the right key for your car, please follow these steps to attempt to synchronise it:
Unlock the doors manually as you have been doing and sit in the drivers seat.  Put the key in the ignition and turn on.  Do not start the engine just turn the ignition on, and note the warning light.  It should come on for a second then go out.  Now switch off and remove the key from the ignition switch.  Immediately press the central locking button on the overhead panel and hold it pressed (it doesn't matter which side) until you hear the locks go clunk, clunk after about 5 secs.  Then press the plip on the key, and the locks should respond.  At the same time please watch the warning light on the dash.  When you activate the system by pressing the central locking button and holding it for approx. 5 secs. the warning light should have come on.  When you press the plip on the key and the locks respond, the light may go out or stay on.  If it goes out, the key should be synchronised and it wil now work.  If however, the warning light stays on for upto 20 secs. it is waiting for the second key plip to be pressed.  In other words it is configured for two keys and it needs both to reset.  You can try the one that you got off ebay, it might work, but don't expect it to.  If it works with just the one good key, great, and if it works with both even better, but if it works with the one good key and then is waiting for the second, which you haven't got (and the ebay one is no good) then after timing out and the warning light goes out, you will probably find the good key will still not work at this stage.

What has to be done next is to reset the system for one key only, then resync. the one good key plip.  This is possibly where you will need a diagnostic computer to interface with the on-board computer to reset it for one key only.  At this stage, it may still be possible - don't take it for granted that just because the Renault dealer said they couldn't connect, all is lost, as they may not have done things correctly, or used some faulty equipment or software.  There can be many reasons, but let's take it a stage at a time.

Go through the re-sync. procedure as I have described it.  Please note exactly what happens and let me know how you get on.  Also please let me have the car VIN and fabrication numbers as I may need that to get the four digit manual unlock code.

Hi Roy,

Many many thanks for your efforts on my behalf, your explanation of the workings of the alarm/central locking system was wonderfull.

In answer to your question with regard to the spare key; yes it does start the car.

I have just nipped out to the car and run through the procedure, as you described, and have found the following:-

When I turn the ignition on, with the spare key, the flashing red warning light on the dashboard, stops fladshing and then goes out completely.

I then removed the key from the ignition and pressed the overhead central locking button for the time you stated.

I then pressed the key fob and it had no effect on the central locking, but in the mean time the red warning light on the dashboard began to flash again.

I hope my explanation of the events is of help, and if you think it is woth it I will find the VIN and fabrication number tomorrow, sorry I can't do it now but my daughter is leaning over my shoulder waiting to go to bed and as the computer is in her bedroom I must go now.

Regards

O.K. that's good.  At least we know the key is correct and recognised by the car.

I then removed the key from the ignition and pressed the overhead central locking button for the time you stated.

O.K. the time is not important here.  When you first press the central locking button immediately after switching the ignition off, the locking system will immediately respond as if you were simply locking or unlocking the doors.  However, as you keep holding it down the system will then respond again after approx. 4 - 5 secs normally, with the double clunk sound and the warning light should come back on and stay on.  This shows the system has gone into re-sync. mode.  If it hasn't done this, then you cannot do the re-sync.  So you need to hold the central locking button down until it responds with that double clunk and steady warning light.  Then you press the plip to re-sync.

You don't mention that above.  Did you get that double clunk?  This is different to normal and quite distinctive.

Quote
I then pressed the key fob and it had no effect on the central locking, but in the mean time the red warning light on the dashboard began to flash again.

This sounds to me like you didn't hold the button long enough for the system to enter re-sync. mode.  The warning light flashing was I assume at normal rate, and therefore was simply the immobiliser system going back active as you had turned the ignition off and locked the doors (by pressing the central locking button).

So please try again but hold the button long enough to get the double clunk, and warning light coming on to show you are in re-sync. mode.

If you hold the central locking button down for let's say 20 secs. and it still hasn't gone in to re-sync. mode then it suggests your system has an internal fault.

However, please try again and let me know the result.

Hi Roy,

Once again many thanks for your continued efforts to solve my central locking problems.

I have just returned from another try at re-synchronising the good key, and with my brother in attendance to keep his eye on the dashboard warning light.

Once again I turned the ignition on, until the red dashboard warning light went out, then I turned the ignition off and removed the key.

I then pressed and held down the overhead central locking button, and after the initial clonk of the door locks operating there was a definite additional clonk, as you described.

I continued to hold down the button but the red warning light didn't stay on continuously but resumed flashing at its normal rate.

I tried the plip but it had no effect.

Sorry for the bad news.

Any further thoughts would be most appreciated.

Many thanks

Regards

Hi Ross,

Did you notice whether your red warning light flashes at steady rate at all times (when not beeing in the car with engine/ignition on). If the light flashes erratically and sometimes even not at all, you might be seeing early stages (I hate to say it...) of well documented 'year 2000 display and/or B-II' problem. This might also explain your dealers very high cost estimate, since I believe the only Renault cure for now, is to exchange the central display and sometimes the B-II (central computer) as well.

The Display/BII problem seems to be most common on early CAN Espace's (I beleive from mid 1999 onwards), and it often shows as flickering (and eventually not working at all) central display, and non-functioning central locking (unless activated from the inside car button). The problem (when still at periodic stage) happens mostly at cold conditions.

The fault seems to emerge in a particular integrated circuit on the display computer motherboard, but there are reports that the 'infection' at later stages 'spreads' to the B-II central computer (not sure whether I really believe in those latter rumors though...)

As said: For now the only official Renault cure is to more or less exchange electronics. I've managed to 'stretch the life' of a completely non working display be glueing a mutter provided with a 0.8W instrument lightbulb on top of the circuit in question. The display and related electronics still works now after roughly half a year. However, this is surely a hack, and I really don't expect it to last forever. I just hope that one day some clever mechanic manage to specialize in exchanging the exact faulty circuits, and thereby saves me and many other Espace owners for more future 1000 EUR bills!!!

Best Regards

I then pressed and held down the overhead central locking button, and after the initial clonk of the door locks operating there was a definite additional clonk, as you described.

Immediately after this is when you need to press the plip to synchronise it (normally).
You could try the process a few times in case one time it does enter re-sync. mode, and try pressing the plip a few times after the second double clonk of the locking system, but the fact that the warning light is not coming on and staying on for 15 seconds, suggests it is not entering re-sync. mode and you have indeed a fault in the electronics I'm afraid.

One further thing you might want to try, is disconnecting the vehicle battery and leaving it off for at least five minutes.  Then after re-connecting, and the system has re-set itself, immediately try the re-sync. process.  I don't expect it to work, but strange things happen with these systems occasionally!

Sorry for the bad news.

No need to apologise to me.  It is you I am sorry for, as it appears you have a major fault and if you really wanted to fix it, it could cost you a lot.  I still say you don't need a complete replacement kit at this stage, since you have one good key. (good because it is recognised by the car and it transmits)  As I said before, you only need a complete kit if you have lost both keys or both are faulty.

It is difficult if not impossible to diagnose these sort of problems further without actually doing the diagnosis myself, partly because I don't trust any other mechanic to do things correctly, or have the same ability (this may sound pompous, but I have learnt over many years from experience, that I simply cannot rely on others especially with these latest complex systems).  I would guess at this stage it is a faulty instrument module, but that is purely a guess and owing to the cost, it really needs a proper fault diagnosis done first.

The instrument modules on these vehicles are linked to the BII computer in a slightly different way to normal, since *both* store the vehicle mileage.  So if you connect another unit (either it doesn't matter) with zero or less mileage than the existing unit, the new one takes the higher figure from the existing unit, and once it has stored the new figure you cannot reduce it.  This prevents anyone testing by substituting another known good unit since the mileage will be altered on connection.

So unless you live close to me and you want me to take a look at it personally, you are either going to have to live with it as you have done so far, or take your chances with someone else.

Hi Roy,

As you say we would seem to have come to a natural conclusion, without further physical investigation.

As you will realise I have lived with the situation for 18 months now so the problem is not urgent.

I would be willing to bring the car to you at some convenient time, if only to buy you a pint for all you efforts so far.

If you want to arrange a get together let me know, and I will see what the logistics are.

It's up to you which way to play it, either I can give you my contact details or you can give me yours.

In any event once again many many thanks for the invaluable help you have supplied so far.

Regards

you can send privatre messages to eachother on this forum, by clicking on the "personal message" link under the persons name/avatar in the left margin.

Its not a very obvious feature (I have toned it down to keep the layout simple), and you may have to post something to make the other party aware, but it keeps private informatrion off the public pages.

- not that the other members are bad guys of course, but other visitors may be :-)

Hi Thomas,

Thanks for your interest in the problems with my central locking.

In answer to your question with regard to the speed of the flashing red warning light, it seems to flash at a constant speed of about 1 flash per second.

When I turn on my ignition the light stops flashing and after about 3 seconds it goes out, and this is when I usually start the engine.

As you say there is more than likely something very simple wrong with the dashboard circuit, but no one seems to have the ability to repair the dashboards, all they want to do is sell you a complete replacement unit.

The best of luck with your car, and if I learn any more about the problem with mine I will post the answer here.

Good luck to all our fellow Espace owners who like us think they are a grat car but sometimes very frustrating.

Regards

I came across the following web site some time ago that may also help as there is a section on testing for Renault keyfob and immobiliser failures and emergency re-codes.
Fortunately I haven't needed to follow their advice/procedure so cannot testify to it's accuracy or usefulness.

http://www.bba-reman.com/content.aspx?content=Test_for_Renault_Key_Immobiliser_failures_emergency_recode

This same company also offer a repair service for your own dashboard....
http://www.bba-reman.com/content.aspx?content=Renault_Espace_Dashboard

and B-II body control modules....
http://www.bba-reman.com/content.aspx?content=Renault_espace_body_controller_failing

and also repair ECU's and other automotive systems as well as supply scanners, OBDII/EOBD boxes and provide an EOBD fault code library on the site. I haven't used them so obviously cannot say from experience how competent they are or comment about their prices but from what is on their web site they certainly seem to know what they are doing.

Stupidly I'd forgotten to make a note of the name or URL for BBA-Reman and it's taken me a little while to search them out again amongst the 100's of people/companies that popped up on Google openly offering their services to undertake mileage adjustments to digital dashboards!!!

Hi Martin,

Thank you for those very interesting links. If they know what they're doing, I guess this what many Espace owners have been waiting for.

Any others on this forum having direct experiences with this company?
