1. Lock your heart and don't get caught in the rain. Flush water because there are small springs inside that can rust and become ineffective and inflexible;

2. Don't put the locomotive keys in a large string, they should be connected in series. When the locomotive is running, the shaking and weight of the keys will wear out the lock, and over time, the keys will slip out;

3. When the key is difficult to insert or remove, slide the key teeth with a pencil and grind the lock core several times;

4. Never add oil to the lock cylinder. Over time, dust can enter the lock cylinder and affect the ejection of the pin, causing it to be unable to open the door. Even immediate lubrication with lead will not work;

5. When the door lock is not functioning properly, spray some lubricating oil on the slanted tongue;

6. Automatic locks (three, four, five sections) should have some slight gaps and not be too tight (such as requiring manual door opening when unlocking), and the lock is prone to breakage;

7. The door gap should not be too large, as it is prone to being pushed open and making shaking noises;

8. The anti-theft door has a checkered pattern, which prevents the use of wire to extend into the inclined lock handle of the automatic lock and pull the door open;

9. Don't use the key to open the door directly. Turn the key to unlock the door, and if the lock doesn't return to its original position, just pull the key to open the door. The lock will soon protest and say goodbye to you.
