Important! : Unlocking ECU

[Begby]

have performed a vts swap into my vtr, after endless amounts of problems ive went to start the car and have orange key light flashing on dash ?
From what I've read I've locked the Ecu ? Not too sure how as I have vts loom Ecu transponder etc although, instead of switching the whole barel I got the chip from the vts key cut with the actual vtr key can only think somethings went wrong there, long story short does anyone have an unlocked single plug Ecu they would sell or can point me in the right direction ?
Any help is very much appreciated.

Guy called chipwizards on here is the person to speak to.Also double check your connections,ie earths etc.

that is correct, there's no need to swap the aerial or the barrel, just the ecu the black box and the chip in the fob.

the aerials are quite fragile things and are common faults, so try swapping to another one.

Will give the aerial a change tomorrow I hope it is just a faulty one, will also double check my earths etc everything lights up an works just can't actually start the car. If not it looks like I'll be giving chip wizards a message. Just wondering will unlocked Ecu sort my problems out guys ? Thanks for replys.

Well yes, the engine will still turn over with a locked ECU too. so if it's not turning over you need to look at your starter circuit.

Other than that, if the VTR was running okay before you did the swap, then I'd imagine an unlocked ECU will solver your issues. If you've not been near the pickup ring on the barrel I'd be surprised if it had failed.

Yeah the VTR was fine until it blew up haha! I've double an triple checked all the wiring etc all seems fine to me,
One thing I've explained I got the vts chip put into the vtr key well an entirely new key to fit the vtr barel but with the vts chip, should I be able to open the doors of the VTR with that key? Looks more an more like i need an unlocked Ecu but thanks very much for the info guys.

Have you swapped the black box up behind the fuse box as well as the key transponder?

The Key, immo box and ECU need to be a 'set'.

[Begby]

When you say key transponder do you mean the kind of black sleeve around the barel? If so no I didn't change this as I was under the impression it simply 'relayed' the code to the immobiliser box an therefore wasn't actually for a specific key is this where I've went wrong ? Out of curiosity mate do you still do unlocking ecus ? What's your price bud.

That's the device reading the transponder. That bit is located in your key and should look like a grain of rice.

no, he means the black box.

[Begby]

Yes, the black box behind the fuse box has been swapped over as well as the Ecu an as I've said about the key.

[MartinObviously]

You've swapped over the right black box and not the central locking relays?

The immob box is about 2 inch square.

[Begby]

Yes mate as I originally ripped out the bigger box which I believe was something to do with the alarm, I will double check the boxes but I'm pretty positive they both looked exactly the same (one from vtr, one from vts). I appreciate the help here guys, I just can't wrap my head around why it's not working lol.

[Chipwizards]

The transponder is a little thing INSIDE the plastic part of the key itself.

It needs to match the immo box which lives up behind the fuse box and has a 'push latch and pull lever outwards' sort of connector on it.

The immo box needs to match the ECU.

All other parts are generic. So, if you have the matching key (black bit, the metal blade doesn't matter), immo box and ECU it should run. If it doesn't run you most likely have something wrong with the wiring.

I can remove the immo from the ECU but that won't fix incorrect wiring so even if I did it it probably still wouldn't run.

[Begby]

Ok ok I fully understand now think I already did to be fair just as I've said can't figure it out.
I will check all the wiring tomorrow, it can't be a loom issue as I got that spliced by pug1off. Can anyone recommend where to start with checking the wiring?
Appreciate that chip wizards, I'm going to switch to the vts barel an try the original vts key tomorrow along with everything else mentioned, cheers guys.

[welshpug]

it can be the loom, you need to check it to be 100%

changing the barrel will do nothing.

[Begby]

Ok I know it "could" be the loom but the odds on them doing a rubbish job are slim.
I'm going to have to disagree there as changing the barel will allow me to use the "original" vts key rather than the one I had cut an coded which there is an outside chance as I have 3 identical Citroen keys that I may have got them mixed up.
Cheers for the input.

[welshpug]

barrel has nothing to do with the transponder, thats in the key fob.

you could be wasting a lot of time and money over a simple switched live or something being on the wrong pin.

[Begby]

I get what your saying mate an I know that to be the case, as I've said though I know the barel means nothing really but it will allow me to use the original vts key in the off chance I've mixed the keys up when getting them done if you follow ? There is a slim chance he's cut my vtr key an coded it to the vtr as well instead of the vts.
I agree I need to check the wiring again aswell from the top of my head the battery lives from the starter can anyone tell me the rest of the lives i should be finding ?

[Begby]

Car fired up today after changing the barel an using the vts key thanks for the help everyone.
