SuperbGlos

Hi all, I wonder if anyone can help. I have just picked up a new superb and using the KESSY. I can press the button on the handle to open, or just pull the handle twice to open the car when I have my key in the pocket. However, to lock I did get demonstrated that I can press the same button again on the handle and it will lock. It worked for me once but now it won't lock, unless I use the actual key fob. What am I doing wrong??? The button always allows me to open the car but not lock it. I can only seem to lock it if i use the key fob. Thanks for all your help. Rob
