Just trying to work out the right transponder that I might buy for the Fabia vRS 2006 (56).

There's (1) AKTP2 - commonly mentioned for FAB coding

or (2) TP24CHIP (newer)

or (3) other, not confirmed .....?

( I am not certain but think the key front AKK237 MIGHT have the TP24chip and the AKK66 is likely to have the AKTP2 ).

What I do know is that the AKK237 on zoom on the hickleys site.....looks like my key / same code inside.

In fact I feel pretty confident I could get this (at twice price of the transponder) and less of a risk of wrong transponder. But the transponder itself that is in the key I am less sure of but could be TP24.....

Has anyone worked out exactly what transponder is required .......?

Look on Ross-Tech's site find out what Immobilizer you car has you can then work out what transponder you need from there.

I would hazard a guess at it having an Immo-4 which is the same as the MK5 Golf (2004 onwards) and uses a TP23 transponder. (Immo-3 uses an AKTP2)

If in doubt phone Hickeys up and ask them.

Correct, but I think its model specific ? So it'd be the next one up? i.e. TP24.

That was kind of a response I had from advanced keys ltd (VW CAN vehicles only for VW transponders).

However unfortunately advanced keys neither had the correct transponder NOR confirmed its identity. But they can (like Hickleys) sell the front key fob itself (AKK237)

Well I spoke to Hickleys too already who "thought" it was AKTP2 and didn't mention any others....but I will beg to differ and at least leave an open judgement on this until its categorical.

I stumbled on the "TP24" in searches and on face value it looks more likely to be the right transponder - but its quite expensive to just "try" at half the price of the front key !!!

Gizmo (sorry about the post in the middle, identities confused due to forgot password but works on my other computer!)

Do you happen to know if the "chip" is truly a chip ? Just that for my car, it definitely had a round tube like immobiliser so doesn't look like a chip !! I know because I tried to retract it and managed to break it !!

That's one thing that rather stupidly, I haven't got around to asking yet. On the Hickleys site though, it does have the appearance of a chip but on others, it looks like like the glass transponder.

Ignore me, I was looking at AKTP24 by accident which is a chip on zoom up - instead of TP24.....! The TP24 being the CAN equivalent chip,

Got both TP24 and AKTP2 on order from Hickleys now anyway, taking the view of coding the cheaper AKTP2 first and if that doesn't work, I still have an unused TP24 which someone could buy off me !

The transponders all look the same (glass tube) i believe there is a chip inside the tube (one i looked at you could just about see inside it.)

Hello

I can tell you guys ! I have a '56 Fabia vRS and it DEFINITELY works with the AKTP2 (SUCCESS!!FULLY WORKING KEY NO NEED FOR DEALER !!!), they sent me thru the post, and I had a little further help with VAGCOM too and coding was a breeze following Sharks advice as well (definitely Immo4)

So, I overordered a little as I wanted to make sure I definitely had the right transponder !

So, indeed, I now have the TP24CHIP megamos !! plus the later new-shape octavia front key blade from hickleys (CAN flick key AKK237). These were the most expensive part of the order too :oD

I don't know if these are of use to anyone

I may get on ebay shortly or see if Hickleys can consider a return with handling fee.....they haven't been anywhere near my car for coding, since I used the principal of "use cheapest first"

(i.e. the £4 transponder AKTP2) - amazed it worked I really wasn't expecting that !!

Oh well not a huge problem

Glad you got it sorted in the end
