Additional Key - programming problems - Help please

Hi steve a few years ago when we were getting the new shape keys done i got Vonnie a brand new audi new style key, it came in an audi bag--BUT it was a fake key ! it did work at first but soon became unable to unlock the car via remote. So i got a proper key and its been fine. When taking the key apart for fitment of the transponder it was assembled different from a proper key with cross head screws if i remember correctly.
Hope that helps. mike

Hi Mike,
Yes it does thanks. I might try and find a different key, my only concern is that I don't want to spend a lot on a new genuine key and find out it is the wrong type and incompatible with the CCCU.

I have just bought a well worn new style key from eBay (£14) just to see if it is compatible (it is also 434 MHZ). I am starting to suspect that the key I have is duff!!!.

Yes, those tiny screws are a real pain, especially when you have had them off as often as I have. The splines have worn off in the heads of the screws now so they are very tricky to screw in and out now.

Cheers

Just need to order the cable you mentioned.

With that cable (the K-CAN, not the VCDS cable) PLEASE never write to the file or change anything, only use it to read the data.

Overwrite the file and your car simply won't work!!!

(sorry for the safety advice, but it is important)

Thanks for the sensible advice.

I do have a remapping cable that i have used, so i understand its best to read and research before changing anything.

Hi Steve,

I've only just properly read this thread, so apologies for this, but I may have some info that might help you.

I changed to a new-style key a while ago as I only had one key, and I wanted to retain the old original key as the spare, and have a new-style key as the primary key.
I don't have the old original spare key with me, so can't verify its part number, but I have info on the new-style key.

When I made the changes I needed to make sure I had a newer CCCU - the AF was my choice.
The CCCU central locking works at 433Mhz, therefore buying the correct key is an important choice.

My new-style key is - 8E0 837 220 K
433Mhz

Cheers

Hi Jeff
Thanks fir that.
I switched to the AF CCCU but still no joy

I suspect it is the MHz tfat is the problem.
I have seen the keys advertised as 433, 434 and 433.9 etc so I mistakenly believed that they were all the same frequency and people were just rounding it to the nearest MHz.

So I will try and get the exact key you suggest and see how I get on.

Dissapointed!!!! Can't sort out a new shape key that works!!!!

Hi,

I have still not been able to get the new shape key fobs to work.

The disappointing thing is that I expected to have problems pairing the used keys to the immobiliser, but that was the easy bit.
I bought some new chips and fitted them into the fobs and used VCDS to pair them to the immobiliser system on the car.
(it was easy thanks to me being able to find the Login PIN for my instrument cluster, with that VCDS can be used to match the new chips to the cluster.

But the problem I am having is the one that I thought would be the easiest t resolve and that is simply pairing the remote operation of the keys.

I know how to pair a new key to get the remote locking / unlocking work and I have done this several times to the old style keys wile trying to sort out the new style key.

I bought some second-hand 8E0837220 K fobs (after realising that the 8E0837220 D fobs are wrong for the A2. But the system will not "recognise" the key when I do the adaption in he CCCU control unit, (code 21). In that when I press the lock button on an A2 style remote key, the system "recognises" it and it works perfectly. But when I try to code the new shape key in exactly the same manner it just won' "recognise" the key.

So I am now stuck, if the system can't "recognise" any of the new shape key fobs I don't know what next?

I now have a new shape key with the right blade and chip so I can start the engine with the new shape key but can't use the remote locking??

Frustrating.

Hi Jeff,

I have now tried two 8E0 837 220 K 433Mhz Keys and the CCCU will still not recognise them.

It has no trouble recognising the standard A2 key fobs (including some secondhand ones I have) but it just won't recognise the 8E0 837 220 K
433Mhz keys I try.

It is not the CCCU (I have tried two) so it does seem that my AF CCCUs are on a different MHZ than the 8E0 837 220 K
433Mhz

The A2 standard keys are 433.90 Mhz, I am no electronic expert but surely the .9 is important (after all the decimal place is important on radio stations after all!!)

I now have a new shape key that I have paired with the immobiliser and so it starts the engine without problems but it just won't pair to the remote locking!!!

It was the remote locking that I though would be the easiest to pair (I was wrong)

VERY frustrating.

Hello Steve, I hope you don't mind me trying to clarify a couple of bits from your helpful thread?
I have one key and want to add another as a spare. I'm not going to get one withe remote locking, just one that I can unlock the doors and start the engine.
I've got VCDS and the VAG K+CAN cables.

As I already have one working key, do I only need one new immobiliser chip programming or do I have to do two new ones at the same time please? (one for the old, one for the new).

Also do I enter '2' in the new value field or just '1' for the one new key to be programmed. I'm a little unclear on whether I have to do anything with the original key to add the second.

I hope this makes sense!

Cheers

HI,

When doing the immobiliser you will just need one new chip. (for the new key)

When coding the immobiliser you would enter the total number of keys in that field - so 2 in your case.

The first key (the original one) will be in the ignition and switched on when you are doing this. So (at the relevant point in the instructions) you would just turn off the ignition (after the immobiliser icon switches off) remove the key and then place it on the passenger seat (so it is not near the ignition barrel) then insert the second key (now with new, blank immobiliser chip), turn on the ignition and the immobiliser icon will go off - Job done!

No problem, I try to give people a quick reply when I can, because if there is a delay while you are trying to do something, the help often comes in too late!!!

Let me know how you get on, I hope the instructions work for you.

Hi Birchall,
Did you manage to get the 434 MH keys going in the end as i am looking to do the same thing I came across this key but also noticed the MH is 434 also I have seen the same key with the 433 MH. Also has any one made or know of a definitive list of key fobs that work ie K,Q,M and so forth?

It looks like the key on that link is not a 200 K. It looks like a 200 and so is not the right one.
You need the K version I have been told.

All sorted !!!

Bought yet another secondhand key from eBay (another 220 K part number one) and it works fine.
The VCDS adaption recognised it as it should.
So the problem I was having was that the other TWO keys I bought were faulty.

So I now have the new style key fully operational, immobiliser, blade and remote operation all as it should be.

So for those that were unsure of the right part number for the key (due to my problems) if you have the AF CCCU version, the 220 K key WILL pair with it.

At last, I was about to give up (something I NEVER do!!!

I will post a new thread summarising all of this and add it to the Links on the new "How to" list, when I get chance.

Steve B
 
Fantastic news Steve! You must be very pleased. :)

When you add your 'how to', would it be possible to list the supported and unsupported CCCU's please? I'm sure someone will be able to confirm which work and which don't. As you say, the AF works, but the Q doesn't, for example.

Regards,

Matt.
 
Good work Steve glad you got it sorted I too will be soon hopefully couldn't find a key in England so I went to eBay Europe and got one on there ended up paying about 45 pound all in but the key looked brand new even for a second hand one.

Hi,
that sounds good.

I found three 220 K keys on eBay at around £25 each but only one worked. So your £45 is cheaper than my £75.

Let me know if you need any help when you get the key.

Hi,

SUCCESS!!!

I managed to pair the remote operation of the locks using VCDS and doing the following

Existing key in the ignition and ignition ON
select control function 46 "CCCU"
Then click on "adaption - 10"
Then enter channel "21"
Click on [Read]
This will display the number of currently stored remotes in "Stored Value". - Mine always displayed "0" as I think all A2s do? so don't worry if yours shows zero too.
The instructions from Ross Tech state Enter your total number of keys up to a maximum of 4(including any existing keys) in "New Value" DON'T enter the total number of keys, instead enter the position that you want to code the key to (4 positions possible) so start with "1"
The field higher up should then show "Adjustment",
Press the lock button on the key that is in the ignition and the field near the top should change from "Adjustment" to "Recognised.
Click on "save" and the first key is linked to the remote operation of the locks
leave that key in the ignition and switched on.
Enter "2" in the new value field and the field near the top should read "Adjustment" again.
Press the lock on the second key that you want to match and the "Adjustment" should change to recognised and then click on save
Repeat this with "new Value" 3 (if you have a third key) to match press the lock on the third key, then click on "save"
Repeat again with "new value" 4 (if you have a fourth key), press lock on the fourth key, then click on save.

You have now matched the keys for remote operation.

To do this via VCDS you need to do the following
put the first key in the ignition and turn the ignition on
place the other keys away from the column (passenger seat is fine)

select control module 17 -"instruments", select block 022 click "GO". if the value in field 3 is 0 then unfortunately the key/immobiliser in the ignition switch is not valid, if it is a 1 then you are fine. You can try this for each key you want to code but this step is optional.
The next bit is important, select block 024, you are hoping to see a zero in fields 1, 2 and 3. if there is a number other than zero you MUST not switch off the ignition until you have waited at LEAST the number of minutes shown in the fields.
Click "Done - go back"
N0w click on 11 - Login and enter your PIN but you must add a leading zero o make the PIN a 5 digit number - click on "do it"
you are now authorised to code the chips in the keys.
go to Adaption - 10 and then enter channel number 21 and the click on Read.
Enter the TOTAL NUMBER OF KEYS that you want to be able to use in the "New value" field
NEARLY THERE
Click on Save, then Done - Go back
The first key is now programmed, remove it and insert the second key and turn the ignition on, the second key is now programmed, repeat for the rest of the keys (if any) but you must do this for the exact number of keys that you entered in the "New value" field earlier.
This must be completed for all keys within 60 seconds !!!

Job done !!!!

Steve,

Brilliant how to. Ive just programmed a second key to my FSI (got the SKC from Tom during a recent visit (thanks Tom)). I am slowly learning how to use VCDS to hopefully provide a localised (East Mids) travelling service for Club Members at no cost.

Thanks again and best regards,

Tom
