Newly bought second-hand houses, which is safer, changing locks or changing lock cores?

You are even welcome to change the lock, which can avoid the suspicion of melon seeds. I told him that I could change the lock when renting a house. When you don't rent a house, replace it directly and take the lock cylinder away, which is safer and doesn't waste money. Children go to school during the day, we go to work, that is, we sleep at night, so the house has some bedding and cooking ingredients, furniture and electrical appliances and so on. Many problems can't be used to comfort themselves, and no one knows when things that don't feel like happening to them will happen to them.

Does the owner need all the keys? If all keys are given to the lessee, it is obviously wrong for the owner to give only one key. You can ask the host to take out all the keys. If neither the landlord nor the subsequent tenant knows the real principal tenant. Children are only part of the danger. Sneaking in late at night, stealing at work, personal danger, directly negotiate with the landlord and ask for a lock change. Don't worry about face. Is it important to consider the safety of your family or face?

Since the house is rented out, nothing will disturb the tenant! As a guest, if you are not practical, it won't cost much to change the lock cylinder, which means that you also feel that there are certain security risks, so it is recommended to replace it. You'd better inform the landlord before replacing it and clarify your concerns. If you don't replace it, he may open your door to steal or do something illegal, so I suggest you replace it. Just replace it with a better lock core, such as super C-class copper lock core, multi-leaf lock core or Ma Yue lock core. These anti-theft effects are good and have little to do with the safety of our children. As the saying goes, it's right to be defensive, but don't think everyone is hard or bad. If there are children at home, change decisively. If you change your mind, it won't cost much. Just make a handover with the landlord when you check out. After all, you must feel uncomfortable when you leave some personal belongings in the rented house and others have keys outside.
