We often face difficulty in turning a key along with several other issues including improper latching and knob problems. We also believe all of these issues to be actually caused by the lock.
In reality, the issue could be something else than the lock itself. You might be surprised to know that most of the time, these problems have nothing to do with the lock. Here are a few problems that may be the cause of the issue:

1. Keys

The teeth of the key are matched with the pins in a lock for a smooth operation. Thus, if you have lost your original key, you might experience problems now to operate the lock with a duplicate one. The key can become non-functional when duplicates are made because any variation can cause a huge difference.
Additionally, the variation increases when duplicates are made from duplicates and the issue persists and, in fact, prolongs. A much better solution is to get your lock rekeyed and have the locksmith make a number of keys. Keys that are made professionally are identical and do not vary in any manner.

2. Strikes

Careless installation of the strike will cause problems even if the door is installed and hung properly. Centre the bolts and latches with their respective strikes. Additionally, do not let the dead latch plunger fall in the strikes opening, and position the strike for the entry lock latch too. Install the strikes with screws long enough to anchor the strike into the framing behind the jamb. Use the screws that are at least 3 inches long.

3. Hinges

If your hinges are poorly mounted or loose, it can cause a lot of problems. A standard door jamb is attached using three hinges with four screws usually. It creates a problem when these hinges are not attached properly. At least one screw should be of sufficient length attaching the hinge to the jamb.
The door will sag if you fail to securely mount the hinges and will interfere with the alignment of the strikes and lock. Calling a professional locksmith such as Perth Locksmith WA for help in such a case is recommended. The first thing we will do is check the gap between the jamb and the door which will help us identify the problem and make the necessary repairs and adjustments.
