Key fob question

[Mr Bigglesworth]

Any one know if a audi remote key fob can be programed to an exeo . If so any one know the exact part number (quite a few say 434mhz, but I don't know if that would make an actual difference .)

Ideally if someone has actually done this before that would be ideal !

 

[Mr Bigglesworth]

If you look in the slot where the blade fits you will see the details of your key, 433Mhz and 3RO.837.220 but even if you get one of these, get a blade cut and match the remote it will not let you past the immobiliser that will need the transponder re-programming.

Thanks, I' be done keys before so know about the transponder and blade, those are more straight forward , but the tricky part is getting a fob to match. I can't find a second hand key fob so was looking at audi keys that end 837 220, but lots of them have a letter on the end, unlike the seat exeo key. and some audi ones say 434mhz, although in the past for some other cars this hasn't mattered to much as both 433 and 434 were really 433.92.

So, my question is whether anyone has either successfully paired an audi fob or knows exactly which part numbers (mainly the end letter) would work?

 

[Mr Bigglesworth]

It was an old MK1 leon

you cant reprogram a used key, at least not with dealer software.

 

[Mr Bigglesworth]

No but you can re-pair it a different vehicle without dealer software (and then sort the transponder and blade)

 

[Mr Bigglesworth]

Sorted! Found a second hand audi fob and paired it successfully. Will get new blade and cut during the week. It's so good to have a second remote (my wife bagsied the first one!)

 

[Mr Bigglesworth]

I'm just going to transfer it from my non remote key, but you can get those coded

 

[Mr Bigglesworth]

Pre 2005 VAG cars were reprogramable, post 2005 transponder is a one shot device, need to replace the transponder, at least that is my experience.

Ok, but I am physically moving the transponder from an old non-remote key to a new key - no need to reprogram. If you need need to reprogram, then if you have your transponder code, quite a few places can program a new transponder for you for not much cost.

Blank blade, case and seat logo badge in the post - should hopefully have a fully operational new key working by the weekend.

If you could post up the part number Mr Bigglesworth that would be handy, I need to get a 2nd remote key.

A couple other questions if you dont mind.
- Can I re-pair the remote with VCDS?
- Will a dealer supply me just cut blade & new transponder programmed?

Hi hugh

So part number was the same as the exeo - i.e. 837 220, and it was an audi a4 one, so it started with an 8E0 (instead of the 3R0 for an exeo).

I didn't use VCDS (which you might be able to use) but the standard repairing method for A4s (off the top of my head something like unlock the door, insert key in ignition and turn on (but not engine), lower window (just in case), lock door with another key and then blip the key to pair - then wait 5 or 10 secs and blip the key to hopefully unlock the car. Repeat and blip twice for coding key 2 etc)

Been out of the country for most of last month so haven't got round to sorting out a replacement blade and I was just going to reuse a transponder from my non-remote key so haven't looked into transponders.

Thanks Mr Biggleswade, I'll try and have a go with that.

 

[Mr Bigglesworth]

Thanks Mr Biggleswade, I'll try and have a go with that.

Let me know, in the end I couldn't find anyone with the info who had got this to work so I took a punt on a key and it worked.

If those instructions don't work then let me know and I'll find the exact ones I used.

Right I have an Audi fob and replacement blade, the fob code is 8EO.837.220 Q (the ebay listing didn't state the Q so hopefully this isnt the problem).

I have tried the methods described on Audizine http://www.audizine.com/forum/showthread.php/428047-How-to-program-your-Audi-flip-key-fob

and this method https://www.youtube.com/watch?v=lb0UdmAVmz4

and have had no luck with either. The Audizine one sounds like the one you described, so I wonder if having the Q in the fob code is causing the problem.

I was hoping to get the fob working then swap the immobiliser transponder over from the non-remote key, which I've located in both so shouldn't be a problem.

 

[Mr Bigglesworth]

I specifically searched through hundreds of listings to find one that had no letter on the end and the same frequency as the Exeo one. Think you probably have the wrong fob - hopefully you can resell it without much cost!

 

[hugh_]

I suspect so. But I haven't managed to get it to work repairing the existing remote key with the non-remote one in the ignition either, so I will get the method right first before I write off this fob.

Using the Audizine method, firstly it is anticlockwise to lock not clockwise, and secondly after the manual lock on the first press of the unlock button the indicators don't flash as it states. I didn't spend that long on it tonight as it is pouring with rain so I was try again when it's dry.,

 

[Mr Bigglesworth]

I have only 1 key, I changed the cell in it and it did not work anymore, I just put it in the drivers door and unlocked and locked a couple of times, it has worked fine since. I think there is a lot of bull spouted re remote matching.

There's a significant difference between matching a remote for the first time and rematching a remote thats had a battery changed.

I have done the process and there is a sequence to it which works and I can adjust each of my remote fobs from being "remote 1" to "remote 2" using this matching process, or even de-learn a key and you can see this in vcds. So no "bull" at all.

 

[Mr Bigglesworth]

And what is the "significant difference" between "remote 1" and "remote 2 " more "bull" in my opinion!

Do you have vcds or have you ever looked reading the responses from the car ECU? If you did can see that the car's ECU is able to differentiate between these, so the whole matching process is not "bull".

Your comments on this thread seem to do nothing to further those actually interested in trying to obtain a second working remote key. Suggest you take your whinging elsewhere and leave this thread, I will not be responding to any more of your pointless posts unless you have anything constructive to say!

Some weeks ago my wife washed my jeans with fob in the pocket.
Tried to blow it dry, hit the button, red light stayed on. After som tries it worked like normal but diddent work on car
Tested the lock unlock on drivers door. Diddent work. Changed battery. No.
Unscrewed and dissabled the fob, diddent work.
Had spare key in ignition, turn to first pos, locked and unlocked the passenger door. Vola!

I have also heard that if you have the unprogramed fob in ignition turn pos 1. You can lock unlock with the buttons on the drivers door, diddent test it.

About fob1 and fob2 i think that it remebers your presets like last temp set, el mirrors set, el seats set.....

Mr Bigglesworth, any idea if a 8PO (Audi A3) fob that is "Hella 434MHz" will work?
It the first without a suffix letter that I've found.
I read somewhere, maybe on here, that 433 & 434 are actually both 433.9x MHz, it is the Hella bit that I'm dubious of?
Thanks
Hugh

That's what I was trying to figure out a well on the mhz.in the end i was lucky enough to find an 8e0 without the suffix and 433mhz. If there is returns you could always give it a go, albeit at small cost. I would say that I would be tempted to stick to a 433 one though.
