So my 3 month old Jetta's Kessy is not working. I can't lock or unlock the doors from the door handles, but I can use the FOB to unlock the doors. When I press unlock on the FOB, the MFD displays "Check Keyless". Also, every now and then while I'm driving teh "check keyless" message is displayed. Does anybody know what that message means? Or how I can get the Kessy to work again? I've tried synchronizing the keys but no luck there.
