Hi Suzy


first of all welcome to the forums



let me get this straight with a couple of questions:-


The keys are original Renault keys?
Pressing "LOCK" on the fob, locks the boot but unlocks everything else?
Pressing "UNLOCK" on the fob, unlocks the boot but locks everything else?

 

Thankyou

Yes they are original keys from Renault.
And yes that's what happens lol

 

if you lock and unlock the car with the mechanical key, does it lock and unlock all doors as it should?

 

Nope just tried it and it only locks and unlocks the passenger door. confused.com lol

 

actually thats what it is supposed to do, it is for emergency opening only, but thought it was worth a test to see if the computer that handles locking and unlocking was having a hissy fit


is this a problem that has sneaked up on you or did it happen overnight that both keys failed to do what they should do? in fact did they ever do the correct thing?


if both keys exhibit the same fault on the car then I have to believe that the keys are fine and the car is at fault.

 

It's had the same problem since I purchased the car. Hence why I brought new Keys. However it didn't seem to solve the issue.

I believe it is something to do with the car, i'm just not sure what. Is there anyway I could check to see if its the original ECU that was built with the car ? To see if someone has changed it

 

I dont believe there is any way to check whether the ECU you have fitted was fitted at the factory, they all carry the same part number they are just programmed differently for each car. Generally because of immobiliser problems a lot more than the ECU would need ot be changed, I wonder if we could "shock" it into coming back to normality, do you have the code to reinstate the stereo if you disconnect/change the battery? it will be a 4 digit code and normally written in the user manual or on a card in the user manual folder. If you have and only if you have - without locking the car, remove the negative terminal from the battery and leave it for about an hour, for all the itinerant electrons to die away, then go into the car and turn on the lights ( purely to mitigate the risk of electric spikes to ECU's etc) then reconnect the negative terminal again, go and turn off the lights now, start the car to make sure everything is OK, put in the radio code if it asks for it, then turn off the car and try lock it, see if the reboot of the ECU's has removed the glitch.

 

I need to change the battery anyway, as its slowly giving up. I will give that a go and let you know how it goes fingers crossed it'll work. Thankyou for your help. As it's doing my head in.

Twice I've been locked out the car whilst its running.. luckily my son was able to open window on the 1st time and on the second my old man has to climb through the boot lol

 

if you are buying and fitting the battery yourself, wait the hours or so before fitting the new one, if you are taking it to a battery fitter, can you ask them to wait at least 30 minutes before fitting the new after taking off the old one and explain why if needed.

 

Go to the boot, lift the tailgate, you will see a rubber tube, possibly twop by the hinge ,, One will feel thinner than the other if two fitted, this will be for washer hose, the other will have the loom in it..
Check to see if any signs of repair on the wiring loom, by pulling the rubber tube down, , or up, or both..
If you see two wires have been repaired, change them around

Its your boot lock wiring at fault, the wires are reversed, either in these tubes, or on the lock,.
No signs of repair there, then remove the tail gate card and check the boot lock wiring

 

HI welcome back


did you try @ours2012 ideas of what to look for and where

Go to the boot, lift the tailgate, you will see a rubber tube, possibly two by the hinge ,, One will feel thinner than the other if two fitted, this will be for washer hose, the other will have the loom in it..
Check to see if any signs of repair on the wiring loom, by pulling the rubber tube down, , or up, or both..
If you see two wires have been repaired, change them around

Its your boot lock wiring at fault, the wires are reversed, either in these tubes, or on the lock,.
No signs of repair there, then remove the tail gate card and check the boot lock wiring

and if all looks ok

Personally would disconnect the tailgate lock, and see what happens.

... would go at the tailgate first

:wink2:

 

Stu I would mentioned that BUT the tailgate is the only lock that works in the correct sense with the buttons pressed, i.e lock = locks the tailgate and unlocks everything else, and vice versa

 

Yes but its the signal, the tailgate does not know what it does, as in, it makes no difference to the tailgate, , it gets a signal, and this unlocks the tailgate,..
( back to switched earth system. If power is reversed here, then the system thinks he has authorised unlock


The motor just turns one way, its not reversed .. It doesn't lock the tail gate,, thats the difference, what happens the power is switched off, so the motor cannot turn, unlock, as in Pressing the tailgate switch, THIS completes the circuit, but when locked, the tailgate has no circuit


Personally would disconnect the tailgate lock, and see what happens.

With him also saying he bought the car with this fault.... would go at the tailgate first

Suzy is female :grin2::grin2:


So Suzy, disconnect the electrical connector to the tailgate lock, and try the key fob to see if all the other doors lock and unlock as they should, if they do then there is a probem with the wiring to the tailgate lock as describe by the Guru above :wink2:

 

Apologies ,, O/P.... Never look at the User name , my bad...
