Car is a 2010 Mk11 Octavia Scout MZ1.
I know this is an old thread, but I want to be sure my particular issue is valid to some of the suggestions in this thread. We lost the last of our 2 keys six or seven years ago and had to do the whole import 2 x keys from Germany (to Australia) and pay to have the car towed to a dealership and then be recoded to the new keys. Six weeks without a car, an x-rayed dog!! and countless hours searching for it ... AUD$1000 exercise in pain.
Lo and behold, today that last key reappeared - like Lazarus, risen from the rotting innards of an old armchair destined for the tip!! It had gone way down below the linings into the spring and stuffing cavity of the chair. The battery is even still good ... red light comes on when lock/unlock are pushed.
My question is, while the key blade obviously works and can open the driver's door, can I safely use the recoding techniques found on YouTube to reprogram that old key to the coding of the new keys (the dealership reset the CPU in the car to match the new keys)? One vid shows putting a key that had a flat battery in the ignition, turning to 'on' and then pressing the 'lock' button to reprogram that key to the car.
I'll happily try it but don't want to compromise a perfectly functioning system. We still have the two new keys, but one does go missing a tad too often and I stress big-time when we only have one key and no spare. Seems like a no-brainer to reintegrate the long, lost prodigal key back into the Scout family ;-) . But if it came to paying another $150 to have the dealer do it I probably won't bother. Any advice most welcome.
