Some Key matching questions.

[Luxus Panzer]

I have 3 different kinds of Immobo chips...

Type 1 = the chips in the existing keys for my car
Type 2 = a blank "virgin" ebay chip
Type 3 = a chip from a different car, in my B7 key.

Please bear with me and my questions here...

Do I HAVE to use a virgin immobo chip, or can the chip in my B7 key be adapted. I am aware that chips can be swapped, if one is careful.

I do have Vag com and I do have a confirmed working SKC to log in to the locked modules in my car.

I want to get my new B7 Key matched. I already got the transponder working.


I came across the following on the Ros-Tech wiki.... is this the correct procedure?

Key Matching with 4-digit SKC
Updated 21 Dec. 2010

Ross-Tech is not responsible for any damage or problems that may result from following these instructions. They are to be used at your own risk.

This procedure details how to match new keys to Immobilizer-equipped VW/Audi vehicles. As of 11 Mar. 2002, VW and Audi are providing 7-digit Secret Key Codes in place of the earlier 4-digit SKC's. Keys must be coded using the new 7-digit SKC (secret key code) method unless the owner still has the correct 4-digit code.

VW/Audi used to give out the SKC to vehicle owners but as of 2005 they no longer do. Unless you already have that information, then you will not be able to use these instructions - you will likely need to have your dealer perform this procedure.

Important Note: Unless you ALREADY have the SKC information for your vehicle and components then you will NOT be able to do any of the Immobilizer functions. Click this link for more information.

Procedure for matching keys to vehicles with Immobilizer in the Instrument Cluster:
(includes many 1999+ Golf/GTI/Jetta/New Beetle/Passat, also Audi)

[Select]
[17 - Instruments]
[Login - 11]
Enter zero followed by the 4-digit SKC.
For example, if your SKC is 1234, enter 01234.
[Do It!]


[Adaptation - 10]
Enter 21 in "Channel Number"
[Read]
The "Stored Value" is the number of keys currently matched.
Enter "new value" of 0
[Test]
[Save]
This clears out the old key-matchings.
Enter a "new value" corresponding to the total number of keys to be matched, including any existing keys
[Test]
[Save]


[Done, Go Back]
[Close Controller, Go Back - 06]
Switch ignition off and remove key


Insert next key to ignition and switch ignition on again
The warning light for the Immobilizer will light up for ~2 seconds, then go out
Switch ignition off and remove key


Repeat step 4 with each key until all keys have been matched.




OR, has there already been a DIY for the B7 FOB that focuses on adapting a new/used chip?

thanks all

I have tried to pair a used key chip with my car but it refused to work, I had to dig out the old chip and install a new one, its not hard to do and finding a virgin chip is easy and cheap, just look for ID48 chips, I think I got 5 of them for cheap off ebay.

Thank you, and as for the process I posted? Is this what you did?

[hightime80]

Thqt is the correct procedure when I made new keys for my car. Provided you have the skc and a new immo chips. Used chip will not adapt to another car once its been paired.

[Luxus Panzer]

and a chip will not adapt to another car once its been paired.

Thanks.

Willy already paired to this car chips still be able to work ?

[hightime80]

Yep. I took one of my old chip out an old fob. Hot glued to a new fob and worked like a charm. No need to readapt.

Understood, just to be clear so I do not brick any of my keys.

I have to reset the number of keys pared to the car to 0 during this procedure...

When I re learn all the keys, the old chips from my car will still be able to be re learnt? and then the virgin key will be hard coded to my car after the procedure?

Or will I need all virgin chips?

Thanks all.

[Human Garbage]

Any chip already paired to the car will adapt again (as will a virgin obviously). You are SOL on the used B7 chip but like chad99 said, they are cheap on Ebay. Search for 'Megamos ID48 RFID'. I got 5 for $10.99 shipped from China last time I bought some.

Bigger issue is getting your SKC to be able to pair the keys with your cluster. I don't recommend messing with your cluster with VAG Commander or VAG Tacho. Much safer to pull your SKC from your ECU. The cluster is encrypted and easy to brick with clone tools. Here is a link on how to do it: http://www.audiworld.com/forums/a8-s...01-s8-2873134/
(Its based on an A8 but Argdub's tool will work on the B6 too- any ME7.1.1.or ME7.5 for that matter, maybe other Bosch ECUs on Alfas and Peugeot too)

I haven't paired keys on my Audi as I got a full set with the car. I have done it on multiple Immo3 VWs. The procedure in the link above works every time.

[hightime80]

Vag eprom programmer! Download it. Use an ebay blue cable and it retrieved the skc good as gold. Tbanks to my man k0mpressed for the tip. It is golden.

you need all existing keys and all new keys and you enter the total number of keys you have and perform the on off process watching the immo light until the end, then I believe it flashes twice and you're done, its been a few months since I've done a b6 but I just did a B5.5 passat a few weeks ago and I believe thats how it went. I don't think I've ever zero'd out the number of keys and entered a new value, I think I just went straight to new value.

edit: here is they way ross tech says, you have to use the cluster way since the B6s store the key data in the cluster.

[Luxus Panzer]

Right on.

I put a new virgin chip in that I had (no idea if it is a ID48 RFID)

I do have Vag com and I do have a confirmed working SKC to log in to the locked modules in my car.

I got my SKC by suing my Vag com cable, VCP drivers and Vag K CAN commander.
Did this a while ago and if I had to do it again, I would use a $20 ebay cable as once the VCP drivers were correctly configured in Vagcom, I could not get my vag com to work again (VCDS) until I removed the VCP drivers.

I used this how to..

I put a blank into this key as well tonight. Once I find somewhere in Ottawa/Gatineau to cut the key for me then I will attempt this adaptation.

Thanks all.

before you try and adapt the process is there to check to see if the key can be adapted, saves tons of trouble shooting time if you run the measuring blocks before hand and make sure your virgin chip is good, had a dud one time that would not adapt.

A Everset Locksmith on Bank cut 4 keys for me, I think it was 20 bucks each. Dropped them off and picked them up the next day. He complained that my ebay blanks were super hard to cut... He also had this unit that could read the immo chips and then program virgin chips. Once my ID48s come in, I'll be trying this.

I already busted one of my S4 immo chips trying to remove it... down to one key now :/

How many ID48's did you order?

[Gosser]

Just two, but really only need one. I'll let you know when I get them and we can meet at the Everest and check it. Buy me a small coffee and you can have my spare ID48. :p

Word.

Lucky he cut them! My locksmith will refuse and throw them back if they are hard. Like he told me, the cutter he trashes on the Chinese mystery metal comes out of his profit margin. Your guy probably just broke even on the deal lol.

[Luxus Panzer]

before you try and adapt the process is there to check to see if the key can be adapted.

How?

[seanf86]

How?

http://wiki.ross-tech.com/wiki/index...hing_(Cluster)

My first link didn't work first few paragraphs, basically put new key in, go into cluster and check the measuring block and it will be a 1 or 0. 1means it can be adapted, 0 is a bad key

Roger. Guess I need to get a key cut first, lol

Let me know when you are going.
