We have this type of lock but it gets lock even when cabin is on ground floor.. Hame zoor se khichna padta hai.. Under wala hook lockbthida niche rahata hai jis ke karan gaye wala hook bahar nahi nikal pata.. Under wale hook ko thoda uper kar ke to thik hogayega.. kya aap bata sakte hai ki ye kaise kar sakte hai . Aap ki help chahiye
