Hi

After help from Hauptmann (thanks!) confirmed that VAGScope won't pull the SKC from the car - access denied.

Also the same result with his latest VCDS and cable when going into the electronics 11 via vagcom with what appeared to be the scratch off. Really impressed with the help he gave me by the way, thanks for that. Clearly though its hitting a security/wrong SKC issue now.

After calling the dealers seems to suggest that I don't really have a 4 digit immo code and this is for earlier models? and if you need to recode a key, you definitely have to get this from the dealer and the plastic scratch off is a waste of space ?

And if this is so, why do they even give the plastic scratch off to us ?

So I am, it appears, going to have to bite the bullet and either get a full key cut from there - at great delay as it can take up to a month (even though I have one and even paired the remote unlocking?!) or get the 7 digit immobiliser code sorted by the dealer and attempt elsewhere.

Does this make sense ? Its a 56 plate car.

So am I the only one with a car this late, stupid enough to lose a key to find this out as I can't find much forum activity for 7 digit codes

Ballcocks.

There are two types of SKC. One is the 4 digit code which is what should be on that keytag you have. This 4 digit code is what is in your ECU and instrument cluster.

The other is a 7 digit code which has to be used in conjunction with some other information such as the dealer's workshop code, importer number and the date on which it was generated. The 7 digit code can be converted to a 4 digit code (which is what the car actually stores the SKC as) with the right software.

A dealer can no longer retrieve SKCs no matter how much you ask them or how much you'll pay them. They can't get it. If they code a key for you they do it with a live linkup to Germany which codes the key directly, automatically. They do not see the code and they do not enter it, it's all automated.

You either need to have the SKC retrieved with the correct, legitimate, not pirated eBay bought software (which I can do for you, as I've previously mentioned) or you can go to the dealer and pay dealer price. Last time anyone I know had a key done at the dealer it took a week to come as it was ordered by chassis number and cost £160+ although to be fair that was on an Audi.

Hope that explains things.

The thing is, Hauptmann and his totally legitimate, vag-com Rosstech cable and the latest VCDS couldn't do it, with my 4 digit code. So please can we move past talking about pirate software, its not relevant to the thread.

It showed "Login Lost due to dropped session"

Again I'm really grateful for your offer but I can't be without my car to post my ECU to you, so looking for help and understanding and grateful for everything so far.

If you also were on my ECU and using my 4 digit code, with the same latest, legit software, or trying to use the VagScope, then I am pretty certain you'd have the same result as him ?

I can only imagine than from what I have read, at a guess that VAG commander is a way to access this 4 digit code on later, CANbus cars (if thats what I have)

Does this mean that someone (and this could only be the Dealers!) could have done something to my ECU, maybe flashed it or something ? That could make for this unpredictable response from the login on my supposed 4 digit SKC that doesnt pair the car ? and why do 2 dealers claim that you have to get the 7 digit code from them for such a "late" model car also. I don't get this, but I don't doubt that the code is encrypted like that. I just don't understand why my 4-digit code isn't working then.

Also was interesting that Hauptmann scanned for error codes, and besides immob warnings, he mentioned about the ABS showing, not as errors but showed as version 00000 which is apparently quite odd also ??

Interested to your response to this.

You either need to have the SKC retrieved with the correct, legitimate, not pirated eBay bought software (which I can do for you, as I've previously mentioned) or you can go to the dealer and pay dealer price.

I'd just like to clarify that the software I used on Domino's car was legitimate and neither pirated nor bought off eBay. Its probably too dated to pull the SKC off his car though (a late 2006 model). I've used it successfully on plenty of VAG cars, but not a Fabia of this fairly recent vintage.

The ABS readings were a bit odd in that software version, part no code strings etc were all 0's. Can't remember seeing that before on any car and just wondered if it had had a replacement ABS module...? On the other hand it may have cropped up before but I just didn't notice.

If they had replaced the ABS at any time, then it was not with my knowledge, although I did moan about crap brakes to the dealer at one point, but they didn't actually do anything that I was informed of, except balance out the handbrake at one dealers, as they found that it was badly out (unlike the first dealers after a little mishap).

This was after I wouldn't go to the main dealers I had the car from anymore after getting a bit shirty with them since the car didn't stop during some fairly low speed mishap where sharp braking was required, and I found the car "didnt stop" and I practically shunted the other drivers car.

Fortunately, and much to the other drivers bemusement there wasn't any damage. Just a loud thwakk and I think all that happened was that my plastic inner centre part of my bumper had been pushed out the grille ! But I think it was a combination of the odd ABS response and crap brakes.

I got over that and just learnt not to trust the brakes with that degree of reaction required, and frankly drive a little less like a twit too.

It was latest Vagcom 908 you used ? I'm not so worried that you couldn't get the SKC using the tacho software (I read that in some cases on canbus cars Vag Commander is better?), moreso that I have a genuine scratch code that doesn't work !

Or not compatible with the vagcom.

It's the VAG Tacho software I was referring to, not VCDS. I'm yet to see a legitimate copy of VAG Tacho.

VAG Commander is what I use which works perfectly on almost every car upto present. It struggles with some of the brand new common rail diesel engined cars but that's it.

Not sure about your ABS but usually they have a WSC and some coding. If you have no ABS warnings then you have nothing to worry about however. When the ABS throws it's toys out the pram it usualy lights the dash up like a Christmas tree.

Your car would not be the first I've seen with a different code to the one supplied.. We had the same problem with Brimma's car when we were going to retrofit Maxidot. How the dealer can give you the wrong one I don't know but it appears to happen.

BTW your Fabia is K-Line not CAN.

Ah thats interesting then at least I'm not alone )

That would explain a lot. So if the commander can pull the SKC then job done, no need for dealer.

I haven't got spare transponder from hickleys yet - I think this is important as its an ebay key and unlikely to code without it, it had no mention of replacing the tranponder.

Checked with Hickleys AKTP2 they think is the right one.

I know a guy on the octavia side had a problem with their transponders for some reason though (had megamos2), hope mine isnt the same. But I would consider this is stage2 of the problem and not to expect to do everything at once! They can get me transponders by tommorow if I order today though

You need to come and take a look at mine then Legitimate lead and software purchased from their UK distributer in Southend.

They are up to v3.40 now, but I can't justify upgrading because it doesn't seem to do a lot more than the v2.6 I have at present.

I do get a little pi**ed-off when other posters automatically assume that any software used must be 'pirate'.

It was latest Vagcom 908 you used ? I'm not so worried that you couldn't get the SKC using the tacho software (I read that in some cases on canbus cars Vag Commander is better?), moreso that I have a genuine scratch code that doesn't work !

Yes, latest and legal VCDS 908. Strange that your code didn't work - you may indeed have the wrong one from the dealer (they might have mixed up the plastic tabs and you got someone else's).

I wouldn't make too much of the ABS info - its just that I don't remember ever seeing a controller with all 0's before and it struck me as odd. If it works OK and since there were no codes showing then all should be OK.

Indeed, that seems to be likely - it doesn't seem to be that uncommon situation with non-working skc's as I thought.

The car itself does do the encoding with its transmitter ?? Strangely a guy at hickleys was quite surprised he though it was only possible with proper key programmers but maybe he just hasn't come across the VCDS/vag stuff.

Im gonna wait to see whether the code can be pulled using the commander if I kindly get some help from shark, otherwise I may have to weight up other options with the dealer. Dont want to have to wait 3 years for a transponder key from them though !

Heads up:

I have my dealer I currently use quoted me £37.50 for coding an existing key.

So I have a (provisional) booking for about a week.

If I find I can get my SKU anyway, allowing for coding outside the dealers then the situation can change - just looking to see if Shark and me can meet up tommorow to test out the commander.

I tend to agree with Shark - the info would suggest that they have it locked down

"4.15 How do I obtain an SKC for Immobilizer and Key-Matching functions?

We do not know of any way to retrieve an SKC for VW/Audi/SEAT/Skoda vehicles other than getting it from an official dealership. Prior to 2002, some vehicles were delivered with a scratch-off panel on a plastic tag that contained the 4 digit PIN code. Starting in 2002, dealerships implemented the WIN2 system to provide SKC's to their technicians and customers. Starting April 1, 2005, VW/Audi dealerships switched to the new GEKO system, whereby their factory scan tools dial up the factory while connected to a car. Under this system, the technician no longer sees the SKC at all and you will need to bring your vehicle into the dealer to have Immobilizer work performed. VAG-COM does not interact with the GEKO system. Check out our Immobilizer Page for more information and procedures."

I can get the front key from Hickleys ( I could in fact just transfer the transponder into the used key part - but is this not a bit risky and could waste money going to the dealer)!

The front key part can be obtained from hickleys (or advanced key shop) AKK65, is I believe what I need and comes to about £25.

(Not AKK237 I guess which is supposedly the Crypto2 and used on Octy II's?). Well I hope not at least.

BOTH use ID48 !!

Argh. I'm getting a bit peed off with this subject now.

I guess I could even find (and I am regretting this) that I could take the AKK65 brand new key to the dealer and STILL find they can't code it, in which case I will go mad !!!

You need to come and take a look at mine then Legitimate lead and software purchased from their UK distributer in Southend.

They are up to v3.40 now, but I can't justify upgrading because it doesn't seem to do a lot more than the v2.6 I have at present.

I do get a little pi**ed-off when other posters automatically assume that any software used must be 'pirate'.

In that case I stand corrected and apologise, but I'm amazed it can't read the car to be honest.

£37.50 to code a key at the dealer is extremely cheap.

Yeah thats my backup plan ! Now only to work out the right front key (if I need it).

I am pretty certain its AKK237 rather than AKK65. Main reason - my inner key matches the first part on the zoom of their image of it, not the AKK65.

It reads PA66 GF50, like the first key on hickleys, and not like the second key (common on earlier fabias from various threads).

So it appears it might be a CAN key. Description on Advanced Key Shop not hickleys:

Skoda: CAN vehicles flick key with Megamos 2 transponder. Use with AKRM73. Blade type: HU66

Again, guessing but I dont think the transponder is AKTP2 after all - I think its likely the 'ponder is AKTP39 Megamos Crypto 2 transponder. ID48 for VW CAN vehicles 2005-2007.

Certainly the age is right for my car.

Also please note that Hickleys dont do that transponder code.

I also think maybe my experiences with coding could prove similar to this thread, he ended up with a load of those AKTP2 which didn't work with his car.

http://briskoda.net/octavia-ii/my-experience-pairing-new-keys-octavia2-vcds/122763/

Futher blog!:

I think the transponder isnt that, auto keys confirmed that AKK237 is the right front, but AKTP39 is not the right transponder either (Nor AKTP2 although at that price wouldnt hurt to try)

I dont think it can be obtained from any of the mentioned companies so far.

It might in fact be this one which can be obtained from others - ( I might be obtainined from hickleys but they didnt describe as skoda and they call it AKTP24? )

Megamos 48 Crypto Transponder TP24 Price - 16.80 EUR

Megamos 48 Crypto Transponder - TP24 for Skoda

Anyway at this price mark, might as well go for the full front key part to be honest, regardless of whose going to code it.

Closure: Not sure about the immo transponder (think I might try a few) but there is one thing that is certain :

My code is actually right !

This is a further thanks to Shark - we met up and he had a going over and had an absolute wealth of knowledge on the car, and of course confirmed my code using the vag commander.

Even testing it thereafter in VCDS - proving it did recode my key so definitely right!

It also proves that the dealers don't always do what they say - I still had 2 keys coded into my car EVEN though the "lost spare" had supposedly been removed.

It turns out my information, and resources I was referring to were not correct for all models.

My model, in fact requires access via a different module (Immobiliser not Electronics). Thats all it was !

I appreciate the help that Hauptmann tried on the car anyway, but obviously (newer) certain models don't always follow the same process so I can appreciate how he'd think that process would work.

I followed the same process, which is listed on the fabia-vrs website !

So thanks to Shark_90 again, and I would have no hestitation with his advice.

It seems offers his considerable knowledge and services, and I certainly consider this without question in future - includes remaps for a really fair price. See his profile. Really nice Octy vRS as well !
