Troubleshooting Common Issues with Safety Padlocks

 Since the development of safety padlocks, we have always needed high-quality products. However, even the best padlocks may occasionally encounter small problems in daily use. Let’s explain to students the common issues they may face with their safety padlocks, along with practical methods for solving them.

1. Shackle not retracting:
Most cases are caused by excessive tolerance in the shackle shape. Insert the key into the lock cylinder, turn it to the proper position, and gently tap the lock body with a small hammer until the shackle moves.

2. Lock won’t turn:
This often happens due to insufficient lubrication or rust caused by long-term use without proper maintenance. Applying a small amount of diesel or gasoline to the lock can effectively resolve this issue.

3. Key stuck in the lock:
If the key breaks at the root, you can remove the broken piece using tweezers or similar tools. If it breaks inside the lock cylinder, you will need to remove the seven-hole seal, take out the lock core to retrieve the fragment, reinstall the core, and finally reseal it with aluminum wire.

4. Keyway blockage:
This usually occurs when the lock has been used for a long time. Spray graphite powder—commonly sourced from pencil lead—into the keyhole. Do not pour lubricating oil into the lock, as it will cause more dust to accumulate.
