What should be done if the lock cylinder is broken and the door cannot be opened?
Door locks can effectively protect the safety of our homes, but they may encounter some problems over time, such as a broken lock cylinder that prevents the door from opening properly. If you need the help of a locksmith at this time, the price will be expensive and you will have to wait. How to solve this problem?
The main reason why the lock cylinder is broken and cannot be opened
If the lock cylinder is broken and the door cannot be opened, you can choose to use an electric drill to drill a hole on the lock box, where you can see the safety mechanism stopper inside. After removing it, you can open it.
01. Due to the loose safety latch button inside the door, excessive force was applied when closing the door, causing the safety latch to shake off. The lock cylinder could be turned with the original key, but the door could not be opened. Some people, because someone is at home and there is something to do at the door, put up the safety latch first and forget it for a moment; When closing the door with force, the slanted tongue of the lock forcefully closed the door without contracting.
02. There are immature children and elderly people with dementia at home who accidentally lock the safety latch without opening it, causing people outside to use a key to open the door. However, even if the door lock is locked with the safety latch, the door cannot be opened.
03. The door lock of the insurance split is locked with a safety bolt and cannot be opened with a key outside. There are two types of safety latch buttons on the lock box inside the anti-theft door lock: one is a twist type button, and the other is a push up and down button. The latter method can only deal with button type safety.
The above method can handle more than 90% of the fault lock caused by activating the safety latch.
Another clumsy method is to use an electric drill to drill a circle of holes in the lock box on the door, and then use a screwdriver to pry the drilled hole larger to directly see the safety mechanism stopper inside. Then, use a screwdriver to move the safety mechanism stopper.
It is also possible to install a circular multi tooth drill clip specifically designed for drilling locking holes on iron doors at the front of the electric drill head. This drill is done by directly pressing into the hole of the door lock to drill the lock box on the back of the door. After drilling into a large hole, it is easy to move the safety bolt steel plate.
How to remove the lock cylinder?
01. First, loosen the disc tightly attached to the door inside, and twist it counterclockwise to move it back.
02. Twist the ball (which is the part you are holding) to the left and right a few more times, look for the small hole on top, insert a small object into it and press it hard, then the part you are holding can be pulled out.
03. At this point, you can take out the previously loosened disc, remove the two screws inside, and then pull it out from the outside.
