Struggling with VW GOLF IV 1.6 Key Coding - Issues Adding a New Key via VCDS

Hey!

I have a problem with adding the key to VW Golf IV 1.6

The problem is that a colleague had one key with a central lock, but the key fell and it stopped working.
Undressing it looks ok, but it does not work. When I tried to add a key with VCDS, I was able to get an error adding the key incorrectly so I decided to order a second one.

My colleague's key was of the old type (not a pocket knife), but I ordered it used original key from Golf IV type of penknife and I wanted to make it
however, after many many attempts, there is still no reaction and success.

I tried both descriptions from the page Ross-Tech :

Quote:

[Choice]

[46 - Comfort module] or [35 - Central locking]

[Adaptation - 10]

Select channel "01" (on some AUDI models it can be "21" channel)

[Read]

The number of currently programmed remotes should appear in the "Value saved" field.

In the "New Value" field, enter the total number of pilots (up to 4) that you want to match to the controller (including existing pilots).

[Test]

Make sure that the controller accepts the entered value.

[Save]

Now you have about 15 seconds to fit all remote controls. Press and hold (for at least 1 second) - in turn on each remote control to be encoded - the UNLOCK button (opening).

If the above procedure does not work - ie both channel "01" and "21" are not available - proceed as follows:

One of the vehicle's keys (old - with coded and working remote control) put in the ignition switch and turn the ignition ON (do not start the vehicle!). When using the VAG-COM program, do the following:

[Choice]

[46 - Comfort module] or [35 - Central locking]

[Measuring blocks - 08]

Select group "003" (on some models it can be group "007")

[Go!]

The value displayed in field number 2 allows you to read how many pilots are currently matched and which positions they occupy in the controller's memory, eg: "0001" informs that one pilot is matched and occupies the first position in the controller's memory.

Now close the car from the outside ("manually" - not a remote control!) Using a combination key together with a remote control that is not yet matched (close the driver's door).

Now, within 5 seconds of closing the door, press the UNLOCK button (opening) in the unmatched remote control. The number of presses of the UNLOCK button is responsible for the position of the remote control in the controller's memory. Pressing the opening button twice will save the remote control in the second memory position, three times - for the third position, etc.

As far as I know, many forum users have changed the usual pocket knife so it's possible, so why can not I make the key?

I would addthat the codon is still showing one coded key, no matter if I give you the number of keys to encode on 1 or on 2. Do you click once or twice on coding.

Does this mean that remote control can only be used to codify new keys?
The tip in this penknife can earn some extra money and immortalize it and I would have an efficient key

You mean the pilot and not the key. The key does not have a central lock.
The car has a central lock and the key is a remote control for it.

What frequency does the new remote control work on?
It is given on the housing.
What frequency does the old pilot work on?
They must be identical, otherwise you will not add a remote control.

As for the key that fell and does not work. It is possible that one transponder leg (such a spider) has been soldered out. I once had a similar failure. I improved February and the pilot lives. As for the penknife, I also mentioned it for myself. Yes, as a colleague wrote above, the frequency with the comfort module must match.

Apparently you do not know what the transponder is and what it is for.
It has nothing to do with the remote control, it is only to immo and has not even one leg.
There is a trimmer in the remote control and it is enough to break and the pilot changes the transmission frequency.

Well, I do not know on the keys but after correcting one leg, the remote control has started working.

I mean, the pilot is not about the key, the old pilot was in the key. I did not check the frequency, I also thought about it but I thought that if I bought from golf IV all of them were on one frequency.
It seems to me that it was 434 MHz or 433 MHz.
As for the condition of solder on the plate and legs, organoleptically look ok, I can try to sell them but in my opinion they are ok ..

where to look for this trimmer? How to fix it?

So there was a few frequencies of the comfort module in Golf IV? How do I check the frequency of my module? on the module? under VCDS? klcuze with an old-style remote control also had several frequencies?

The first remotes had a frequency of 433, then 434MHz.
The frequency is on the remote.
There were two types of comfort module:
- without CAN for 433MHz 1J0959xxx
- with CAN on 434MHz with number 1C0959xxx
The trimmer is a potentiometer that changes the capacity. I advise you not to shoot it because you need a pilot tester to set it up, which will show the frequency. You will not set it without it.
Trimmers were only in pilots on 433MHz in those not folded.
The old type of pilot was in the first years as in the last year of the Golf 4.
Even Fabie from 2006 had the same type of remote control but they were no longer on 433MHz as well as those from Golf.
The pilot fits well with Leon, Toledo 2, Octavi 1.
There were versions for 2 CR2016 batteries and one for CR2032 but I do not remember if it was a frequency determinant.
The former were for 2 batteries, the newer ones for one.

Ok the car is from 1998 so it is one of the first, so I understand that it is 90% at 433MHz, after the comfort module it would be easy to check it but currently interested is on the road.
So I understand that I will order a pilot at 433 MHz and it should be ok, and apparently the one I ordered was 434 Mhz. The remote control is so tattered that you can not see the subtitles. For sure it was for two batteries and the newer pocketknife was for one battery.

Thank you

It's rather like you write.
There you need to look for a penknife with rounded buttons.
It looks as if the shape of both buttons formed the shape of an egg. Remotes where the 2 corners of the button are rounded (those in contact with each other are not rounded) will not work here.
The pilot is to be with 2 buttons.

I bought a brand new key at 433 MHz so it must be good as it comes, I'll let it know if it was.
Thanks!

Okay, the case looks like a new key with ID48 transponder, the key is on 433MHz (remote control) and now the question arises how to use the VCDS to correctly encode the transponder? apparently it is only programmed once. I read something on the forums that I have to read some pin could anyone accurately describe the coding procedure of the new immo in Golf IV 1.6 1998?

Do not be afraid, you will encode it there 20 times.
You need a pin.
It is stored in the meter's memory or was on the key tag under the scratch card.
Needed VAG, counter, adaptations, channel 21, number of keys, ok, put another key into the ignition and turn on the ignition for 5 sec.

Ok, so I understand that there is a lot of coding.
I do not have the tags with the old key, so I need to read the Pin from the meter.

I have VCDS, CARPROGA AND DIGIPROG3 I'll read one of them PIN after OBDII ?

Do I have to undress the meter and read the Eeprom?
I understand that the addition of immo / transponder under VCDS is:
Instruments [17]> adaptations> channel 21> approx
where is the pin given? and zero or zero (4 or 5 digits)? The car will be in the evening but I want it to work well.

edit:
I've found three more procedures, but none of them has anything about channel 21:

Quote:

1. IMMO1 - a separate BOX with immo (http://wiki.ross-tech.com/index.php/Immobilizer_I_Key_Matching_%28Separate%29),
2. IMMO2 - key adaptation procedure (http://wiki.ross-tech.com/index.php/Immobilizer_II_Key_Matching_%28Separate%29),
3. IMMO3 - key adaptation procedure (http://wiki.ross-tech.com/index.php/Immobilizer_III_Key_Matching_%28Cluster%29).

What IMMO is there?

immo2
Adaptation, channel 21.
After OBD, VAG TACHO will go.
You will pull out the memory and read it by Carprog.

How exactly does he sit there to remember? Do you need to desolder it? because CARPROG does not show how in meters to connect with an adapter, but probably OBD II
Is read fault memory and erase fault meomry ...

I enter Carpogie in IMMO> WW> GOLF IV RB8 >> I connect OBDII and now this way:
"READ IMMO" pops up no response from kontroler; /
when he gives READ FAULT CODES he sees part number and type: WEGFAHR COMBI.
But you can not read the immo (READ IMMO).
Can I desolder the Eeprom memory and read it with Carprog? I guess I can only pull out the PIN from the batch later?
What memory is there? can I put a batch here and someone with a PIN code? Come, I'd rather know for myself in the future

How do you get this PIN?

I undressed the meter I have memory and 24c02 and 93lc56 ??

which of them to read from eprom?

Added after 47 [minutes]:

here's the batch of 24C02 the original from the counter can someone read the pin?

Mileage: 213914km?

The case has been solved and I received a PIN from the coil from the forum that read it, but in the future I would like to know how to get it out myself.
And the central remote control was able to code according to the instructions I had previously uploaded.

The mileage is 213 thousand. A friend of mine whom I drive already from 4 years, but whether this course is original is another matter, because in my opinion the 24C02 bone was already desoldered earlier when I looked organically at her
I asked ... says he is not going to change the course, D

Added after 1 [hour] 23 [minutes]:

So in the future, if someone had the same way:
I bought a new key with ID 48 transponder and 433 MHZ key.
I have read the input from 24C02 using CARPROGA, you can also use any programmer, for example USB UPA

a colleague from another forum gave me a valid PIN.

then using VCDS and as colleague @ grala1 said (thank you very much for the info) I went in:
INTRUMENTS [17] >> LOGIN (here we give the pin which has 4 digits and zero in front of the pin)> Adaptation> channel 21 >> and the number of keys to be encoded I had two, old new one.
now you hold one transponder, wait until the Immo icon on the meter goes off, turn off the ignition, switch on and another transponder.

I made the coding of the central unit according to the instructions:
[Choice]

[46 - Comfort module] or [35 - Central locking]

[Adaptation - 10]

Select channel "01" (on some AUDI models it can be "21" channel)

[Read]

The number of currently programmed remotes should appear in the "Value saved" field.

In the "New Value" field, enter the total number of pilots (up to 4) that you want to match to the controller (including existing pilots).

[Test]

Make sure that the controller accepts the entered value.

[Save]

Now you have about 15 seconds to fit all remote controls. Press and hold (for at least 1 second) - in turn on each remote control to be encoded - the UNLOCK button (opening).

Earlier, I could not have coded it because the old key would probably break down and the second one I bought was on 434 MHz and I needed 433 MHz.


Thanks cordially for all the help!
