Probably like most hosts I use a Lockbox with a combination lock but I have had major issues with the box jamming and have now lost two because they won’t open. I only have one set of keys in the box, removed the key ring to prevent jamming and yet it’s happened again. I’ve tried to hammer the box to unlock but not budging. So I’ve put a combination box in place. Has anyone had this issue and do you have any recommendations going forward? Thanks Emma
