Troubleshooting Lock Issues on Hinged Doors

From time to time the Seconline Help Desk are asked to assist in rectifying some of the issues that arise when both single lock security/barrier doors and three-point lock barrier/security doors are installed by our customers. The Austral locks that we use are an extremely robust and effective lock with very few moving parts within the lock mechanism; however, these locks must be installed correctly and receive a degree of maintenance depending on the usage for effective long-term use.

When you receive your door from Seconline it will be in a cardboard package which you will have to remove. The best way to remove this is to put the door on a flat surface or on some work horses and using a sharp knife cut around above the staples but not outside the fragile tape and completely remove the upper part of the carton. This will reveal the door and its lock contents which will be in a separate sealed bag. Remove this lock package and install the lock handles using the screws provided. Please note the chrome internal locking snib device must be installed in the 12 o'clock position when the door is unlocked. This is an extremely important point that must be adhered to so as to have the lock working correctly. When the door is locked this snib should be in the either 10 to or 10 past the hour position and if this is not the case then you need to remove the handles and rectify.

  1. To test whether the lock is locking correctly prior to installing the door you will need to proceed with the following:

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

  3. Release the handle and throughout the entire procedure do not touch the handles again

  4. Directly above the main locking tongue is a small trigger: press this trigger with your finger to release the main locking tongue out into the full locking position

  5. With the internal chrome locking snib, now lock the door lock

This should move freely and as stated above the chrome locking snib should move into either the 10 past or 10 to position.  If you have a three-point locking mechanism this should engage the top and bottom locking tongues into the fully deadlock position simultaneously as well. Repeat this action several times quite aggressively to make sure that you have a good audio and visual feel of the lock mechanisms operation.

Now proceed with the installation of your door and the lock mortise hole cutouts and at any point during the operation repeat the above scenario whilst the door is in the open position to identify whether the problem is with the door jamb and not the lock. If at any point you have restriction in the locking position while the door is closed and this scenario is not able to be repeated whilst the door is open then it would suggest that you have restrictions within the mortise holes and you will need to satisfactorily alleviate any restrictions for the locking tongues.

Prior to leaving the Seconline factory in Mudgee your lock is fully tested and lubricated. It is rare that the locks would be faulty and be shipped, but may be possible. In most cases it is the actual fitting of the door to the doorjamb where the problem with the lock occurs and is usually solved by following the steps above. Ongoing maintenance is required and a sheet is provided that suggests if you don’t have some lubricant such as silicon spray then it would be a very good idea to purchase some and apply liberally, particularly to the trigger above the main tongue, regularly. It is very difficult to know exactly how much lubrication your particular door will require; suffice to say that it will depend on the use and the amount of contamination such as dust or salt that may be in the air. Having said that we would definitely encourage you to maintain lubrication of the lock as it will allow trouble-free use for many years.

If by chance the guidelines above does not fix any lock issue you may encounter with your Security Screen Door contact the Seconline Help Desk on 1300 735 405.
