Troubleshooting Hinged Door Lock Issues: A Step-by-Step Guide

Dealing with lock issues on hinged doors can be frustrating, but with the right guidance, you can ensure your lock functions correctly. Follow these steps to troubleshoot and resolve any problems you encounter:

1. Install the Lock Handles Properly: Begin by removing the lock package and installing the lock handles using the provided screws. An essential point to remember is that the chrome internal locking snib device must be positioned at 12 o'clock when the door is unlocked. This correct alignment is crucial for the lock to work correctly. If the snib is not in the 10 to or 10 past position when the door is locked, you must remove the handles and rectify this.

2. Test the Lock Before Installing the Door: To check if the lock is functioning correctly before installing the door, follow these steps:

a. Pull down on the door handle to engage the main locking tongue on the central locking body.

b. Release the handle and avoid touching it again throughout the procedure.

c. Just above the main locking tongue, you'll find a small trigger. Use your finger to press this trigger, releasing the main locking tongue into the fully locked position.

d. Lock the door using the internal chrome locking snib. The chrome locking snib should move smoothly, as described earlier, into either the 10 past or 10 to position. If your lock has a three-point locking mechanism, it should engage the top and bottom locking tongues into the fully deadlock position simultaneously. e. Repeat the above action several times vigorously to ensure you have a good understanding of how the lock operates.

3. Test During Installation: Continue with the installation of your door and the lock mortise hole cutouts. At any point during the operation, repeat the above scenario while the door is in the open position. This will help you identify whether the problem lies with the door jamb rather than the lock. If you experience any restriction in the locking position when the door is closed and this issue cannot be replicated when the door is open, it suggests that you may have restrictions within the mortise holes. In such cases, you must address these restrictions to ensure the locking tongues can function properly.

4. Consider Factory Testing: It's worth noting that before leaving the Defendoor factory in Newcastle, your lock is fully tested and lubricated. While it's rare for locks to be faulty and shipped, it is not impossible. However, in most instances, lock problems occur due to improper fitting of the door to the doorjamb. By carefully following the steps outlined above, you can troubleshoot and resolve lock issues efficiently.

By following these steps, you can troubleshoot and resolve lock issues on hinged doors, ensuring your lock functions correctly and provides the security and convenience you need.
