The burglar-proof doors are usually installed outside the entry doors and the gap between the two is small, so the door locks chosen by people are often the spring locks without any handles to avoid the handle being slamed into the burglar-proof door and the door being unable to be closed. 

Bedroom locks
They are installed on the doors of each bedroom, which should guarantee the privacy of those bedrooms. That is, the door can be locked if we are inside the bedroom and the key should be used to unlock the lock if we are outside the bedroom.

Besides, it would be better if it is available for people to open the door outside the toilets or bathrooms, and otherwise it will be bad for rescue when some accidents like faint, coma or even poisoning happens. What's more, bedroom locks should also have waterproof and rustproof functions.

Passage locks
