Many people have problems with entrance doors, especially if the structure is old and has not been maintained. Not everyone knows what to do if the door does not open from the inside or outside, it is impossible to get into or out of the apartment. You can solve the problem yourself. You just need to know how to act in a given situation. But if it doesn’t work out, local locksmiths will come to the rescue.
A common reason why an iron door does not open or the latch or lock does not open is that the mechanism is clogged. This happens often, especially if the door is installed outdoors. Dust and dirt get into the keyhole. All this complicates the operation of the mechanism. To clean the system, WD 40 is poured into the keyhole. This liquid vanishes rust and softens dirt, making it easier to remove. But you need to give it a little time for it to take effect. Then try to remove the blockage. This can be done from the inside or outside.
The key was lost
If the door is closed and the key is forgotten at home, it is broken or lost, then you can open the door lock by making a master key from two hairpins or paper clips. They are inserted into the keyhole and rotated in a certain way to move the bolts away. You can try to open the door by pulling back the tab.
Sometimes it is impossible to open the door if the key is inserted from inside. You will have to drill out the cylinder or remove the door leaf from the hinges. The reason for the poor functioning of the system may be a manufacturing defect. This can lead to unstable operation or rapid breakdown of the lock.
