Bedroom Door Lock

Bedroom Door Lock

Some maintenance of high-end door locks

High-end door locks are difficult to open or open, which is the need to "oil" the lock, but the 

lubricant of the lock is not grease, but the pencil core. The pencil lead is made of graphite. When 

the graphite chips are blown into the lock hole, it is equivalent to the oil being locked, and the lock 

is opened.


The high-end door lock was frozen and the key was not inserted into the keyhole. You can use a 

hot water bottle to put hot water on the lock and warm it for a while. The lock is opened after 

warming and freezing. You can also gradually insert the hot key into the keyhole, and be careful 

when turning the key to avoid damaging the converter.


If the key is broken in the keyhole due to excessive force when unlocking, do not panic. Insert the 

broken key handle into the lock hole to make it fit perfectly with the other end of the hole in the 

lock hole, and then force it in. Push and gently turn the handle of the key to open the high-end 

door lock.
