Don't forget your key when you go out.

It is common sense for women and children to take keys when they go out.

There are all kinds of locks, so are the keys. There is a kind of copper lock that used to be very common, with an oblique long lock on one side and an unusual key. Only old people remember it, but it should be an antique now.

Traditionally, doors are locked to prevent petty criminals. In the past, there was nothing valuable at home, and the villagers all looked up and looked down. Therefore, the door facing the street is generally not locked. Just close two doors to prevent wild dogs and night owls from entering the house. Naturally, the key was left at home.

With the improvement of people's material life, people's awareness of vigilance is also increasing. The doors are getting thicker and the locks are getting more and more exquisite. The emergence of security doors caters to the security needs of modern people. Now there is a fingerprint lock, so you don't need to bring a key. However, even the best security doors are vulnerable to thieves. No matter how good the lock is, the thief can easily open it, but it is louder and easy to expose the target. As the saying goes, if you are not afraid of thieves stealing, you are afraid of thieves thinking. Once the thief thinks about it, it is not a good thing.

Remember to bring your keys, but sometimes you forget to leave them at home when you go out. At home, General Tie left the door and keys at home, so outsiders couldn't worry.

Take a bunch of keys when you go out. At home, in class, in the office. Sometimes I open the office drawer, but I suddenly find that I don't have my key when I come home from work. I hurried back to the office, only to find that the key was still safely inserted in the drawer, making people speechless.

It's embarrassing to lose the key. I often see the revelation of looking for something on a roadside telephone pole: whoever finds a bunch of keys, please call to receive the reward. Then the relatives went home to open the door, and the key could not be put down. I even thought about changing the lock. I couldn't find it after a while, so I had to match it again. Now the buttons are all numerically controlled, and it will be done in a few minutes.

If you lose it, you can get another key, but if the lock core is broken, you can only spend money to change it. The security door of the vegetable cellar at home was still intact when it was opened, but it was closed and the key could not be inserted into the keyhole. I have no choice but to ask a professional to unlock the lock. Look at the professional tools used in the lock opener. He pried the lock from left to right, and soon removed the old lock and replaced it with a lock core lock. After the completion, I was repeatedly told that the lock core would not be easily damaged when the key was always with the moon tooth facing up. I suddenly have an inexplicable fear: the anti-theft lock can be removed so easily. What kind of theft is the security door? Maybe my idea is purely alarmist. Anyone who opens the lock will have such a bad idea unless he doesn't want to do it again. And once the household is stolen, the lock opener is the first suspect.
