Hi all, I bought a fabia with only a manual key to open the doors, of which only the drivers door opens, but thats the central locking motor in the door at fault, I hope!

I have bought 2nd hand key fobs for it, and have had some new blades cut that work a treat in the ignition, apart from starting the car! I have tried the programming procedure that my autodata tells me, but that doesn't work! So, is this possible or have I bought a coupe of fobs that can't be re-programmed?

Any help with this would be grand!

Thanks in advance,

Craig!

If they are the usual "filp key 3 buttons..." They key is actuially 2 parts. The back 'arf is the alarm part with the button and open/close/disarm the alarm etc. The bladed bit has a transponder. The transponder has to be known to the car in order to disable the imobiliser. That requires software coding tools and the secret number (sorry forget the tech term) of the car....

Short form: Alarm bit is easy, inmobiliser bit is tricky.

Thanks for that! Would I be able to code the immobiliser transponder with the aid of a launch or similar vehicle diagnostics computer, do you know? Or will I i need to replace the transponder with a new blank one?

Also, this secret number? Is it within the ecu or can be found in paper work?

Cheers bud,

Craig!

<p>Probably a new transponder of exactly the same type is needed.</p>

<p>The car can be set to code the key using special software, I think VDS included as I had help with this on mine. Not difficult but requires the right process and the right tools.</p>

Yes you also need the SKC which is in plastic fob in the car docket hopefully.

If not you hope to be able retrieve it using something like vagcommander and again the right tools/right person/right method.

This may be handy

You can remove the transpOnder from your current key and replace the one in the new key with it!

The reason it won't work is the small glass transponder isn't coded to the car. You can either pay a dealer to code it in for you (ouch) or depending on the age of the car you *may* be able to retrieve the SKC on older cars using (am I allowed to mention names?). The cheaper and easy way is to find your local auto electronics specialist, they should have the kit to be able to clone the transponder in your working key and after that it's just a case of following the guide above to sync the remote. While you're at the auto electronics place get them to remove any key's that are associated with the car but you don't have, it saves a lot of agro if someone still has one.

It's also easy to convert 'standard' keys to flip keys, a blade can be cut from a photo and a second hand fob coded in as per the process in the link above, you can then either butcher your existing standard key for the transponder (free) using a hot knife and a bit of nail varnish remover then glue it into place or go to an auto electronics specialist.

Thanks for all the suggestions, I was going to invest in a VAG COM system anyway, so Ive bought one, when it arrives I'll let you know if I needed to replace the transponders etc!

Just got to get that SKC code, if this computer requires it!

Thanks again, I hope to get it Friday, so will let you know what happens the weekend!!! Fingers Crossed!

Craig!

Thanks Avalon, I have the flip keys all cut and working, just got to program them to the immobizer and sync to the central locking. This computer I have bought will do that and more! How would you find the SKC code? You didn't mention.....

Thanks for the detailed reply though!

Craig!

You can't find it unless you still have a tag with it on (they haven't come with them for a number of years now) or maybe something like vag Tacho or vag commander to read it.

Technically it's supposed to be a dealer visit.

Can any soda dealer tell you? Or dOes it have to be from where the car was bought, I don't fancy a trip to Scotland that's for sure!

If it means going to skoda then it will have to be, and if its got to be the one that registered it in the first place great, a nice day out!!!!

I'll post back what I find!

Ta!

You should be able to take it to any skoda dealer. I had a second key made up for the Fabia I just bought and I didnt have to take it to the place it was registered. Just a word of advice though.... Dont take it to capital skoda in Newport!! Took mine in to get the key coded on a sit and wait job... Went in at around 1:00pm and didnt get away until just after 3:30. All they did was code the key and change a few rear lights!! Customer service was shocking!! Apparently the car was ready and waiting for ages, they just got caught up in other stuff every time they were about to tell me :(

Any Skoda dealer will do but any decent auto locksmith will be cheaper.
