Store kitchen door Unlocking by removing foreign matter

"There is a foreign object in it and the key does not stick"

As usual, when I point the key at the kitchen door to prepare for opening, it doesn't stick.It looked like a keyhole, but I just stuck it in.It is said that the key is no longer stuck.

U9.MA lock.We proceeded with the keyhole cleaning work of normal work.After a few minutes until the oil soaks in, the lock is safely unlocked.If it does not open with this, it will be a gap attack, but it was unlocked by normal operation.

As far as I could see the keyhole, no foreign matter was confirmed, so I performed overalls by disassembling and cleaning.A few millimeters of black object appeared, but it is an unknown foreign substance.

The reflection meeting this time was about to accidentally pull out the core and almost knock off the spring of the locking bar.He always holds it down carefully, but forgets it.It is a reflection.
