B7 Key Fob for B6 DIY

[T0M3K]

Any word on immo chips? I will go to the dealer and see what he will say (probably in lines, you can't do it)

[panamared16589]

Will the free version of Vag-Com allow you to do this

Will the free version of Vag-Com allow you to do this

To my understanding you can only clear codes with the free one not make any changes. Some one can correct me if I am wrong though.

don't think so
you need pn starting w/8EO and ends in R or L

Ok...I definetly plan on doing this soon.

Few questions:

1) What the hell is the immo chip, lol? Is it that capsule looking thing next to the blade?

2) Also, Are we switching the green electrical boards from the B6 to the B7?

3) For some reason, ever since I bought a new laptop (went from XP to Vista) my VagCom no longer works. Does it only work for XP?

4) How come initially you said you cut you existing B6 shank....but then said that you took it to a locksmith for it to be cut?

EDIT* Just bought a used/cut key for $31 shipped so hopefully my questions will yield positive, lol

1) Yes
2) No
3) Not sure
4) You can modify the B6 blade yourself (with patience), but he said that that if you have an uncut B7 key, it might be difficult finding a locksmith/keycutter that can cut side-winder keys like ours.

Thanks man for the help!

Bump for the vagcom working with Vista question!

[T0M3K]

Bump for not hijacking the thread. Vista troubleshooting will take a while. Start new one and indicate what kind of interface are you using.

I will try to go the dealer and see if he can make me another key or "fix" the one I broke. In worst case I will mess around with valet key by cutting plastic till I get to the immo chip.

[absolutegtr]

just got my new key in and it so damn lame that they require a T6 torx to remove the back....where can i buy one? Is there anything I could substitute for it?

[derleicaman]

^^^Wiha Tools, Sears, Ace Hardware. You might try a 00 Philips, but you'll prolly bugger up the screw head.

[absolutegtr]

Alright, well one of my friend has a T6....so said 'fug it' and attempted to modify the shank of the kwy for it to fit the new remote. I actually got it fit perfectly except it wiggles just a little bit more than I would like....still closes and opens fine though.

Can I buy a new uncut shank anywhere? On ebay they have the longer shanks but not the newwer/shorter shanks

[absolutegtr]

Its been like two weeks now since I made they B7 key and I still cant find torx bits of T6

BTW, are you POSITIVE they were T6 (the two smaller ones)...my friend is a mechanic and I tried his T6 and it was too big. (he didnt have any smaller size!)

You're right, it's a T5! I just noticed that I had it wrong!

I got mine from Wiha

Quick Tip for those who have there little glass "transponder chip" glued in:

Instead of trying to dremel/file around it, which is not a smart idea, lol...hit it with the heat gun for about 30 seconds on both sides of the remote. Mine was glued in place, I heated it up and turned it upside down and it just fell right out

[desairs]

hey guys do you know if this will work for a c5 A6? I am just wondering because the fcc id will be different. Any help would be awesome.

[audi808a4]

so say i have matching cut B7 keys. all i have to do is swap the immob chip, and vag the keys?

[T0M3K]

^^ Yes

[desairs]

was that by anychance a yes to my question about the c5?

[T0M3K]

derleicaman,
how much you want for virgin immo chip. Mine is done, I rather take B6 key to dealer, program it, and then just swap.

PM me and we'll talk. Out of town till Sunday night.

[A4-to-rs4]

So if i buy a new b7 key it can work on my car but dealers dont want to program them?

[Rockdarrel]

So I'm just getting into the world of modding and this is definatly one that I want to try. I am also just getting into Vag Com and want to try a few things out. So now for the stupid question: I know that you can link into the cars "brain" via the connector port and control different settings, but how can you reprogam a key Fob with it being a completely seperate unit with no way of direct PC interface? Does the Fob chip communicate with the sensor in the ignition and allow you to program it from there?

[Hotel Guy]

so I did the modification and the key works in the ignition no problem. So I took the new key to Rennart in Chicago to have it vag-com'd and they werent able to program it. They said (and showed me) how the key wasnt being recognized when you pressed the lock/trunk/unlock buttons on the B7 key (the red light on the fob lights up, though). Anyone have any idea why the fob isnt being recognized? I purchased the key from ebay.

[todd1010]

So let me get this straight.

I've got a B6 S4, so I can or can't just buy a virgin B7 key fob with an uncut key and have it programmed to work with my car?

The main statement above is that it needs to be a virgin because then the dealer won't program or cut a key then, correct?

[JohnnyG]

your dealer should be able to cut the key but it will be up to the parts guy. All B6 keys are cut in house but the B7 keys are only ordered by vin for security purposes... something new. But if you tell 'em to cut it to match your B6 key they are capable. FYI check your new b7 keys for compatibility and for gold battery contacts, the first production runs had a few issues.

[audi808a4]

FYI people, this mod does NOT work with an 02 a4 or models with the control module 8E0959433T you can only do this mod with an 03+ or need a module that is 8E0959433BB in order for your new B7 key to be recognized. the module is interchangeable but for 415$ part (module) alone. Unfortunately i found out the hard way and had to purchase a new key. but meh, not that bad i guess, i did need a spare key. just wish my spare didn't consist of two keys lol (B6 key as remote and B7 key as key)

This is good info, something I did not know! Sorry it didn't work out for you.

[catriple]

Thanks for the DIY. I was able to make brand new 4 brand new B7 keys with your help!

Hooray for brand new shiny updated keys!

[desairs]

so still no word does anyone think this will work with a c5?

[Kengineer021.8]

You will have to obtain a B7 Key Fob. If you can get one with an uncut blade, you're way ahead of the game. A good source for key fobs is eBay. Do a search for “Audi Key Fobs�. You can find them for as little as $25. The more expensive ones advertise uncut blades and virgin immobilizers. You can always buy one at the dealer, but their pricing is around $300.

Just saw this link on ebay... pretty much just what the doctor asked for:

why would u want a b7 fob? i dun get it ... they're not that cool

Cool enough when your old one looks like a worn out POS. The B7 keys seem to be a little more durable in terms of materials used. Should stay looking nicer longer.

Plus, common wisdom was you couldn't do this, just like a lot of other things we do with our cars. Like the man once said when asked why he climbed the mountain, "Because it was there!"

[47Ronin]

I guess ... lol i mean you can say the same for why people put giant ass wings on their car

[aaron1085]

sick mod..well done!

[Gondi Stylez]

If that's true about '02's then I'm SOL.... shitty

[absolutegtr]

Info on 2002 models:

I am not to sure on that.

I am STILL waiting in a T-5 torx bit. I have already retrofitted the shank of my B6 key to fit the B7 remote....ANYWAYS, When I turn the car on, it immediately turns off, which is obvious why...but once, just once, I turned the car on with the remote and it ran perfectly fine.

As soon as i can get the transponder in the B7 remote, i will hook my VAG up to it, and I will let you all know!

[derleicaman]

Go direct to wiha.com, click for US sales, for Torx drivers. Always excellent service and I got mine in a few days. They also have the bits. Where did you order yours from?

[derleicaman]

Picked up a Torx set with bits and driver handle today at Home Depot for $5. Good deal and certainly very handy to have in your tool box!

[zbrock06]

if anyone is looking for some B7 key fobs I have used ones, i can get them from my friend and he has 23 key fobs and i'm just trying to help out audiziners, not making money on it just passing on the information. shoot me a PM if interested.
