1. The lock should not be exposed to rain for a long time. The rainwater that falls contains nitric acid and nitrate, which will corrode the lock.
2. Always keep the lock head clean and don’t let foreign matter enter the lock cylinder, which may cause difficulty in opening or even failure to open.
3. Regularly inject lubricating oil, graphite powder or pencil powder into the lock core to help reduce the oxide layer left by the long time of use.
4. Pay attention to the thermal expansion and contraction caused by the weather (wet in spring, dry in winter) to ensure a reasonable fit between the lock body and the key, and to ensure the smooth use of the lock.
