Superb 4 kessy problem

When setting up kessy, it doesn't respond to opening the door. It's happened to me once and then it started working again out of nowhere. 

when I set the door to open when approaching, it always works, but this option doesn't suit me. When I press the button on the key handle(nfc)the car locks, but if I want to open the doors, they don't unlock.

Does anyone have the same problem or have any advice on how to reset or "fix" it? 
turning the kessy option on/off and then trying to open by door handle doesn't solve the problem.

Ad : when i turn on option to unlock when near the car its working just fine and it unlocks so i assume key is not the problem.

I have the same issue. But it has happened to me when outside temperature has been around 0 (or below) and when there has been some foggy rain or snow.
Will take my car to dealer for diagnostics next week but not sure if they can figure out something. 
Also @QuinFin had the same issue as mentioned here: 

 

Dunno why kessy open the car with me standing near to it then. If i enable this option in menu.

there is nothing frozen or whatever. It just dont have signal i guess in those conditions? 

I Tryed to bring two other keys near the car and it worked. Then i walk away with all the keys and tryed the 1st one and it worked again too. Will try it again in the morning coz i didnt had mobil phone with me maybe some signal issue too will see

 

its some glitch with signal or connection. I dont think its done by weather
