I've had a 2005 Octavia Estate and have just had to dispose of it after 241,000 miles. I've replaced it with a Octavia 1.5 2023 Estate with 128,000 miles on the clock. The Car warehouse place I bought it from only provides one working key, but there was another in the pack that doesn't work with the car. As the actual physical key in this second key doesn't actually match the on what works and that the Skoda logo is missing from the second key I have strong suspicions that this key has never worked with this car! I've tried various hacks from YouTube videos, but with no success. Is this a lost cause and I'll need to buy a new key or should it be possible to make it work with my car?
