There are a few problems with the doors of my newly constructed house. For few of the interior doors, the door lock is not operating properly. I don’t know whether it is the problem of the door lock or with the mechanism. Because of this problem, we are not able to lock the doors of the room. One of my friends suggested to replace the locks but one other friend asked me to get it repaired. What should I do now? I’m planning to hire residential locksmith services. I think replacing will be the best option because replacing the entire lock will take less time than fiddling with the parts of the existing lock. What are your opinions on it??? Home security is very important because you never know when your home can be a target of burglary. So I think it is always good to make the doors secured.
