Skoda Superb 2012 Mk2 KESSY driver side stopped working

[Thorn]

My driver side keyless KESSY system suddenly stopped working. Works fine on passenger side front door handle, and with the remote/key buttons.
Any tips/suggestions?

Typical issue of broken keyless antenna - use VCDS or any other diagnostics tool to check the errors.

To @Thorn - I have some Problems with my "Kessy". Sometimes work OK, sometimes not. I change the key battery and everything is OK

Thanks tuningmania.
I have two keys, new batteries, both have stopped working completely on driver side, both work 100% on passenger side :-(

Thanks,
I will do a diagnose then.
Do you know if the antenna is in the driver side door handle, and exchangable? Or will I have to change the whole handle?

Not pretty sure, sorry :(
