Congratulations on your purchase!
If you're having issues with the central locking (i.e. the car refusing to do anything) then this is an issue that affects a small number of current-generation Corsas (both ICE and BEV). It's intermittent (happens to us once every few weeks), and I believe there isnt yet a fix. For now, it might be a good idea not bother with the garage as they may charge you for the diagnostic time. Hopefully there will be a fix soon. Fortunately, the manual key is easy to remove from the fob and use.
In other news, we tried out the pre-conditioning this morning. Ambient temperature around 6 degrees. It took around 10-15 minutes and 0.9kwh (13p on our tariff) to get up to temperature.
