Water and electricity charges are paid normally, and the property is cut off from water and electricity. Can I change the lock myself?

Water and electricity charges are paid normally. If the property is cut off from water and electricity, you can change the lock yourself. Of course you can change your own house. If you have your own house, of course you can change it. You can change the lock core if you rent it normally, and you can change the lock if you buy it yourself. As long as the rental contract does not stipulate that it cannot be changed, just change it.
