Hi folks,

I know this has been covered a few times before, but it's my first post so be nice :p

Having just bought an 05-reg vRS with only one 3-button flip key (my fault for assuming until I picked the car up, feel daft but oh well) and quoted over £160 by the dealer for a replacement I thought following some great advice on this site I'd have a go at cobbling together my own.

I can see some people appear to have had some success with this whereas others advise against it. Hope I've not bitten off more than I can chew

I've got myself a cheap VW key fob off ebay (I know) with the same model code/frequency as my existing one. I've already removed the transponder from that, hoped it would come out in one piece but having seen the amount of glue holding it in I can't see that ever being possible. Now I'm fairly confident I'll be able to get the remote working with the central locking, the bit I'm wary of is matching the keys to the immobiliser...I've only really used VCDS for looking, not changing anything, and I'm completely paranoid about it. Which is odd, 'cos I work in IT and if it wasn't a car I probably wouldn't give it a second thought!

Anyway, although I can't work out whether it's 100% the right one for my car, I've ordered a transponder model AKTP2. At £4 plus delivery I'm happy to give it a blast.

Soooo... here's the thing... say I've got the wrong transponder, or have made some other balls-up with the mongrel key, what's the worst I could do if I try to match the keys? I use VCDS and follow the process to match 2 keys, it first clears any existing stored keys, then after the original one what happens if the second key fails to work for whatever reason - is the first one still ok to use? Guess what I'm asking is am I risking leaving myself without a working key, or would I have to be really pretty daft to manage that?

There is an easy way to adapt a new key if you have a good original.

Adaptation using an initialised (adapted) ignition

key

– Insert the mechanically operational (adapted) ignition

key in the ignition lock.

– Switch on ignition.

– Lock the vehicle mechanically using the new key (to

be initialised) and briefly press the radio buttons.

– Press the radio button on the key once again after an

interval of more than one second (end key initialisation).

– The required adaptation process is confirmed by a

brief horn tone.

Saves faffing about with VAGCOM etc

Oops, finger trouble on my previous post..

Thanks for that MoggyTech, guess that's the procedure to code the keys for the remote locking? I'll need to do that as well but I meant matching a key (transponder) to the immobiliser - I wasn't very clear, sorry...

It will still code a key (adapt it).

Cheers guys

And if the second key fails to work with the immobiliser, I can just start over, follow the procedure again just coding the one (current, known good) key I guess...?

Will hopefully have the blade and transponder by tomorrow, will have a crack at this over the weekend. What could possibly go wrong...

I too am missing a key (went spastic at the sales guy) - from reading that other link I take it you need to use the VAGCOM thing.

My local Skoda dealer wants £100 all in for the new key but I have been some on the bay going for silly money. Can I get a new blade and re code a key that has already been coded for another car?

You need to be fairly picky with ebay keys, if the transponder has already been coded to another car I'm not sure if there's a way to recode it to yours. Quite a few keys on ebay with virgin/unused transponders but I don't know how you tell if it's the right one for your car. Do all VAG 3-button flip keys use the same transponder? Suppose not... You'll probably need to look elsewhere if you want a new transponder chip/capsule thing. I'm new to this, someone will be along to correct me in a minute....

There are a few sellers on ebay who will supply and cut a new blade by digital photo / key code for about a tenner. Not sure how good they are but I'm kinda hoping 'good enough' as I'm waiting for one to be posted out.

By the time you add on the odds and ends for the key, the VCDS license and cable cost, maybe £100 from a dealer for a guaranteed complete new key doesn't sound quite as bad. Was this quote from a main dealer? My quote was over £100 inc VAT just for the fob and blade, then add on another £60+ for the coding

You need to be fairly picky with ebay keys, if the transponder has already been coded to another car I'm not sure if there's a way to recode it to yours.

All you need to do is take the new key out of transmitter range and press a button more than 200 times. The car then fails to see the key as the code hopping sequence is broken. You then adapt the key as in my previous posts.

Ok, now I'm confused. Not particularly difficult, like, but....

Three parts to a key I thought - the blade, the remote locking transmitter, and the immobiliser transponder.

I thought the radio transmitter for the central locking had absolutely nothing to do with the immobiliser transponder and you had to match both to the car completely separately? MoggyTech, if I take my ebay key and fit my newly cut blade and follow the steps you're describing, can I start my car with it? Surely I'd need to follow the VAG-COM/VCDS bit Warwick posted too?

Am I over-complicating this?!

The transponder has nothing to do with the remote and none of the advice given in this thread will code a key to your immobiliser. You need your SKC and VCDS to code a key to an immobiliser, and it needs to be a brand new transponder.

Hi Shark

That's what I thought. Don't suppose you know if an AKTP2 transponder sounds right for a 05 Fabia vRS key (immo 3 I think) ?!

If I use VCDS (I have my SKC) to try to code my second key and it fails - say I've bought the wrong transponder - can I just run the process again for my one current key to get me back to square one? Bit paranoid about the "clear existing keys first" step...

Ok, well in case anyone's thinking of trying the same thing - it worked perfectly.

- Old VW 3-button flip key from ebay £15 (split the two sections of your key apart and check code, it needs to match, mine was HLO 1J0 959 753 DA)

- New blade cut to key code from ebay £10 (need either key pattern code - not SKC but another of the numbers from that tag, or just a couple of good digital photos of existing key would do)

- Transponder AKTP2 from Advanced Keys £10 (Hickleys also do them)

- Skoda metal key fob badge from ebay £1

Key needed to be hollowed out a fraction with a dremel type thing as the new transponder was a little larger than the original one and it wouldn't clip back together. That was the only hitch, the link provided by Warwick above works perfectly for the coding. Note there's an additional step for paranoid buggers like me on the Ross-Tech website - step 4 on the link below lets you check that the electronics of your replacement key are ok to be programmed...

So one brand new (ish) key for £36 all-in and less than an hour's work. Well chuffed.

Even if you didn't have VCDS it would be worth buying that and a cheap ebay cable and it would still come in well under my dealer replacement quote.

Hi There,

 

I know I am dredging up an old thread, But I have a skoda fabia which has only one key, and I want a second.

 

I have borrowed a laptop and cable with VCDS from my work (technical training college) and am a computer technician myself.

 

I am tempted to try to program a new key.

 

I have a paper tag that came with the car with lots of numbers on it (presumably the key codes etc)

 

Can someone talk me through the motions of what to do next?

 

Alan

- Insert the mechanically operational (adapted) ignition

key in the ignition lock.

- Switch on ignition.

- Lock the vehicle mechanically using the new key (to

be initialised) then remove new key from door lock and briefly press the radio buttons.

- Press the radio button on the key once again after an

interval of more than one second (end key initialisation).

- The required adaptation process is confirmed by a

brief horn tone.

 

I've just used this to adapt a used key I bought off eBay this week. 

 

First I pressed unlock on the new key 200 times to clear it.  (Just to be sure.)

 

Then I followed the slightly adjusted method above. It maybe just fluke, but I tried it several times unsuccessfully with the new key remaining in the door lock. Then I tried it after removing the key and it worked.

 

Also, the horn didn't sound, but everything seems OK.
