One: What should I do if the spring in the handle lock is broken?
"The shackle spring is stuck and cannot be retracted. This is likely due to a spring within the lock mechanism. First, try gently tapping the shackle with a hammer. If that doesn't work, remove the screws securing the door from the inside, remove the back of the lock, loosen the screws on the lock, and open the cover. Then, reinsert the spring that controls the extension and retraction of the internal locking mechanism. If all else fails, you should contact a professional locksmith.
Two. If the spring in the "hand-crank lock" is broken and the lock cannot be opened, what should be done?
There are generally two common methods to open a lock with a broken spring:
1、 The only option is to remove the lock. First, use a screwdriver to unscrew the metal ring at the handle, which will reveal the screws. These can then be easily removed from inside the room.
2. If you are unable to open the door yourself, we recommend calling family and friends for assistance, or directly dialing 119 for emergency help. If you have the phone number for a locksmith, you can call them to come to your location.
Three. How to maintain door locks to avoid damage.
1、Minimize the use of lubricants.
In everyday life, when a door lock becomes stiff after prolonged use, people often apply lubricants to it. While lubricants can effectively lubricate the lock, prolonged use can lead to the accumulation of oil within the lubricant, which may be contaminated by dust and clog the lock's mechanism, thereby reducing its lifespan.
2、Utilize pencil shavings effectively.
Wax and pencil shavings can be used as a lubricant for door locks. Using pencil shavings can prevent the door lock from becoming stiff and can also restore the door lock to its normal function.
3. Gently open the door.
Additionally, to ensure the door lock's longevity, proper usage is crucial. In normal operation, doors should be opened and closed gently. This helps prolong the lifespan of the door.
