Octavia III Keyless Door Antenna Fault

Hello, I have Octavia III with keyless system and a Fault in Kessy: 1057291 - Antenna for Keyless entry system; Passenger Side (open circuit). I disconnected an Antenna in Passenger door, made Kessy coding without Kessy Door Handle Passenger Door. But still have this Fault and notification in the Dash  'Keyless access system faulty'. Does anybody solved this problem in this way (by disconnecting and decoding)? Or it is necessary to decoding with ODIS online or to do basic settings or adaptation? Thanks

I found in 09 Central Electronics an Option: 'Bit 0 Keyless entry System (Kessy) installed'.
Is it for Entry & Start or Entry only? In other words If I remove it will be able to start a car by pushing Start button with the key fob ?

I did try and it works. Engine starts by pushing the Start button, no message in the Dash and no Keyless Entry.Thank You for help

Hi mate!

I tried coding, but it was unsuccessful. I changed the coding in 05 - Acc/Start Auth. and also tried 09 - Central Electronics. After changing the coding in 09 - Central Electronics, the start button stopped working and an error appeared as well. Do you have a fix for this?
