Reprogramming Audi Switchblade Keys Craig Liess 2000

The previous FAQ entry on this item had some mistakes (and it confused the hell out of me) so I decided to make it a bit more user-friendly and add a few tips and pointers.

I'd imagine these directions will work on any A4/S4 with the "switchblade" keys. If you own a TT, A6, or A8 with these keys, try and see if the directions below work, and e-mail me your results.

These directions will allow you to reprogram your remote-control "switchblade" keys to full functionality. The '00 S4 manual claims that if you press the buttons too many times outside the range of the car, the key will deprogram itself. I don't know the reasoning behind this.

You will need BOTH of your "switchblade" keys to reprogram one or both of them.

  1. Take the key you DO NOT want to program and put it in the ignition. Turn it one click forward.
  2. Close and lock the drivers door with the second key.
  3. On the second key (the one in the drivers door) press the 'UNLOCK' button ONCE only. The lights will flash on the car, but the doors will remain locked
  4. With the second key still in the drivers door, unlock then lock the door again.
  5. Pull the key from the slot and test remote functions.
  6. Open drivers door, remove key from ignition.
If both of your remotes don't work, do the above for the first key, but on step #3, press the 'UNLOCK' button twice. The lights will flash twice, then continue on with step #4.
