How to match the door key if it is lost?

If the common lock used in your home is better matched, remove the lock or call a professional to remove it at home.

Generally speaking, there are two ways to match. One way is to try to open n keys, which will be easy to match if there is a good chance. Another method is to remove the lock core and match it according to the elastic piece of the lock core. This method will not be difficult, but it will take more time. The first method is recommended. If it doesn't open, change it to a new one.

Matters needing attention in using keys

1, when in use, if it is a new lock cylinder, it often happens that the key is not inserted smoothly. At this time, most people will think that the quality of this lock core may be problematic. In fact, this is a relatively normal phenomenon.

If this situation is found, some graphite powder can be added to the keyhole to make it lubricate, and no oil substance can be added. If grease is added, it may stick to the marble spring, causing the lock to not turn.

2. Hold the handle when closing the door, and then screw the locking bolt into the lock body. After closing the door, you can loosen your hands and don't slam the door hard, otherwise the service life of the lock will be shortened.
