Hi all

Recently my car has been a little difficult to start and it seems to be only with my key. I believe that my key is one of the original keys (2002). My wife’s key that is only 15 months old seems to have no problems (although used less). I have been told it is due to the chip in the key fob not turning off the immobiliser quick enough??? Audi wanted me to buy a whole new key but is it not possible to remove the silver key from the unit (looks like a watch style pin holding it in). Attach this part to the spare front half I have and clip this to the current 3-button section?? Would I then be able to get a Vagcom user to program the immobiliser?

Any advice would be good. thanks
 
It is possible to remove the blade. I bought a blank blade key fob with remote included off ebay with the same part number for my a4. I was able to program the remote myself with Vag-Com, got the blade cut at a locksmith but as I didnt have the "secret code" for the immobiliser, I had to get the dealer to program in the immobiliser, which cost €55.00.
You only need to buy the half of the key with the blade in it (make sure its the same part number or the immobiliser will not work) and you can fit your cut blade into it. You would have to get the immobiliser chip programmed at the dealers though if you dont have the immobiliser secret code.
 
I have an extra half key with the blade, but there is no part number on it . Is the part number only on the remote section? Therfore any imobaliser section can be used as they are generic over the range? But a trip to audi will be require. Just dont want conned into buying a new keyfob!!
 
As far as I remember there was a part number on the blade section of mine, inside on the plastic. I thought it was the remote that was generic and the immobiliser was part number specific. Maybe I have it the wrong way around though. Let me check it tonight when I get home and I'll let you know tomorrow. I'll get a pic of it too if I can.
 
Hi, sorry for taking so long to come back to ya. Checked that and you're correct, there is only a part number on the remote section which you need to match up but the immobiliser is generic.
 
The problem is it seems to happen with my wifes key to! andit is new! It has only happend once since Saturday and the car has been started about 50 times since then.
 
must be a problem on the car end so. something to do with whatever device detects the immobiliser chip in the key intermittently not detecting correctly. If its happening on both keys Id say the keys are fine. Anyone ever have this before?
