Solutions for Doors That Will Not Lock05/14/2015 Back To Blog
When security door locks fail to lock right, problems begin. Needless to talk of the consequences since it is obvious that the house will be susceptible to burglaries and you will hardly get a good night's sleep. In order for you to understand the main reasons for doors not locking well, you ought to understand the way deadlocks work. The main part of the mechanism is the bolt, which comes out from the edge of the door and must be inserted in the small hole of the strike plate, which is found on the doorjamb. When the bolt fails to enter the hole all the way, the door does not lock well. In this case, someone could use a card to open the door or just kick it down. Let's discover the main reasons why British standard locks have problems and how you can take care of them.
Simple solutions for locking problems
There should be a specific distance among the door and the doorjamb in order for the bolt of your security locks to be inserted into the strike plate hole. In a different case, the dead bolt will fail to do so and it could be easily bypassed. The distance between the door and the jamb should be about 1/8 inch and loose door hinges or weather strips might cause problems. So, take care of door issues to avoid lock problems.
The dead latch will also fail to enter the strike plate if the latter is misaligned. In this case, you must pay attention to the screws keeping the plate in place. Lock the door with the door open and check if the bolt is at the same height with the strike plate hole. You can also check the screws of the plate since they can be loose or one of them might be missing causing the plate to be misaligned. In such cases, straighten the strike plate before tightening the screws.
Sometimes, problems arise due to bad lock installation. The door won't lock right if the mortice is not deep enough. You will have to remove the strike plate and enlarge the mortice. Pay attention to the edges of the strike plate and the plate of the lock mechanism on the edge of the door. If there are rough edges, use a metal file to make them smooth or they won't allow the door to close and lock well.
