As I understand it you want the bit that the flip key attaches to.

That is the bit that contains the transponder for the Immo.

You sound like you have the rear section which is the bit that controls the remote locking.

That's right, I need a new transponder. I bought a complete key but as the transponder part of it is no good I need a new one. :eek:

For clarification

To my Knowledge you can't buy the transponders separately from Skoda - you can't even get key blanks from them. If it was me I would risk the

The transponder looks like a little maggot for want of a better word. But they are usually bonded in now and break before you can get them out.

In the keys of yesteryear they used to fall out when people changed the battery for the key torch..lol Then they wondered why the car wouldnt start afterwards.

To my Knowledge you can't buy the transponders separately from Skoda

When using the term transponder I am reffering to the top part of the key which houses the transponder.

That will be key and transponder assembly, which will be the smallest part that Skoda will sell you (pre-cut to a key number) in order for you to get what you want.

Like your site by the way - very well presented an imformative

Thanks mate.

As I am sure you know, you can buy the key and transponder assembly from ebay but as I pointed out earlier you need to check the part number before buying.

There is also a guy that will cut you a blank from a digital image.

Unfortunately all of the items on ebay seem to go by part no of the remote rather than transponder part no. I bought a unit with a matching remote part no but it appears the transponder had been locked so it could not be coded to another vehicle.

I bought a transponder from here...

http://www.hickleyvaltone.com/diagnostics/keys_list.php

Part No. AKTP2. This is what it looks like (about 12mm long)

Tried to code it to my IMMO and it didn't work the first time but did the second time. It is now correctly recognised every time I use it.

Another problem though, I have tried to code the remote part of the key by following the Ross-tech instructions by entering the number of keys into measuring block 01 of the cent. conv. control module.

The measuring block appears to be the correct one as it shows Keys Count 1 (only one remote matched at the moment). However, when I try to update the value to 2 it doesnt let me.

Procedure used:

Enter channel and press read (fields show one remote is currently matched)

Enter new value of 2 and press test. Test value shows 1. No matter how many times I repeat it the value remains at 1 and the save button is never enabled.

Can anyone shed any light on this behaviour? :(

I haven't yet tried the manual programming method (key in ignition, lock driver's door with other key, etc.) as I only have 1 key cut at the moment.

For anyone wondering how I coded the IMMO transponders with only one working key I simply detatched my original key shaft and used that!

Finally, does anyone know how to open the transponder case so I can replace the original with my working one? I have tried and tried but all i've managed to do is chew the plastic up around the edges. Are these things glued together??

Steve

To open the top part of the remote (bit with the key on it)you need to remove the small badge carefully so you can stick it back on afterwards.

Once you have the badge off, you will find a small screw underneath. Remove the screw and the plastic part splits in two. You will find the imobiliser chip gluded in.

With care you can remove it and insert the new one.

Hope this helps.

For the remotes you usually have to erase the original programmed vaules iirc.

Adaptation, channel 00.

Thanks for the help guys. Wondered if there may be a screw under the transponder badge but didn't wanna ruin the badge so I drilled a hole through the side of the case which also removed the old transponder. Popped the new one in and hey presto. The drill hole is now out of site when the remote is attached to the transponder.

Got my new key blade through, attached it and followed the procedure in the car handbook for re-synching the remote. Simple procedure....press any button on the new remote then unlock the drivers door with the physical key. The remote was immediately matched with no need for VAG-COM or the key in ignition and lock door with another key, press buttons, etc procedure mentioned everywhere else.

I have two new glass transponders (as pictured above) so if anyone has purchased a dud key off ebay give me a shout, they may just be what you need!

Good news and thanks for the feedback and offer.

Mr.Janiels

i might be needing your offer

i have bought two keys off ebay but have trouble everytime i try programming the immobiliser, it comes up with fault code 11776(i think) incorrect key programming with the two additional keys but will program the original key everytime no problem. bloody keys.

and whats this manual method of coding the RCL fobs??

Have you sorted this yet Ben?

nope, but to be fair i haven't done anything about it since the weekend

hi, could someone please help me. when using vag-com to programm a new key, the save button is not accessable. Why is this? Am i doing something wrong?

Tried here?

Are you using a genuine Ross-Tech interface (cable) or a cheap clone?

If the latter then that is your issue.
