What should I do if the lock core doesn't open well?

For safety reasons, every family will use locks. However, after the lock is used for a long time, if it is not well maintained or used improperly, it will make it difficult to open the lock core. What if the lock core is difficult to open? Let's take a look with Bian Xiao!

What should I do if the lock core doesn't open well?

1, if the key is not smooth in and out of the hole, you can go to the store to buy a box of kerosene, and squeeze it a few times at the keyhole with the sharp mouth of the kerosene box to let the kerosene flow into the keyhole. After a few minutes, the key can go in and out smoothly. After the kerosene flows in, it will automatically volatilize in a certain time, so there is no need to worry about the greasy lock core affecting the use of the lock. 2. If kerosene doesn't work, it may damage the internal structure of the lock cylinder. This situation requires a professional lock repairer to repair it.

Daily maintenance methods of locks

1. In order to keep the transmission of the lock smooth and prolong its service life, it is recommended to check the lock once every six months, and check whether the tightened screws are loose to ensure that the screws are tightened.

2. In order to avoid unsmooth key insertion and removal, lubricant can be used regularly, or a little pencil powder or graphite powder can be added into the lock core groove, but it should be noted that other oils cannot be used instead of lubricant, so as to avoid oil stains sticking to the spring, resulting in the lock head not being opened or damaged.

3. Always check the lock body and lock plate, and pay attention to whether the height of the lock tongue and lock plate hole is appropriate. If there are any changes, adjust their positions.

4. The lock cylinder should avoid contact with water. If there is moisture, the small spring in the lock core is easy to rust after a long time, which leads to the inflexible use of the lock core.

5. Try not to string the keys together. For example, when the key is hung on the key of a motor vehicle, it is easy to wear the key when the motor vehicle is moving, resulting in the key easily slipping out of the lock cylinder.

Bian Xiao concluded: The above is about how to do if the lock core is difficult to open and the daily maintenance methods of the lock. Everything is inseparable from daily maintenance. Paying more attention to maintenance methods and usage methods in daily life can increase its service life. I hope it will help everyone.
