Professional analysis｜The culprit of loose C-buckle: often "using a key to pull the buried metal gate"
Many residents are accustomed to directly using the key to hook and pull when closing the metal gate. Long-term lateral pulling will cause metal fatigue in the C-shaped buckle that fixes the thin key barrel, and gradually shift or even fall off. Once the C-buckle is loose, the upper bead, lower bead and slingshot will lose their fixation and pop out, causing the lock key to be unable to align after being inserted, or even the entire set of parts to jam the lock cylinder. 101 Tips for opening locks: Use door handles or gate handles when closing the door, and avoid using the key to apply force; check the stability of the lock cylinder every two years, and make an appointment for maintenance immediately if it is found that the rotation is not smooth.
