6/9 is "Rock Day" The latest key is maintenance with a pencil etc.

June 9th is "Lock Day". It is an anniversary established in 2001 by the Japan Lock Security Cooperative, "Let's review the keys and think about crime prevention."

"In response to the picking burglary that peaked in 2002, the door key has evolved into a precise one that is difficult to invade. On the other hand, because we are using a new highly crime-preventive key, we are You can't just rest assured that it's okay. The higher the security of a key, the more "precision machine" it is, so if you don't maintain it properly, you may not be able to demonstrate its performance or it may break down. " Saeki Sachiko, a safe life advisor.

The key got sick, and I was bothered by saying, "It's okay because it's fully equipped with an auto lock." It seems that there are many cases where a key defect has led to crime damage. She was there and she was taught by Miwa Lock, a major key maker, about specific key maintenance methods.

"The more precise keys with high security performance such as dimple locks, the more easily they are affected by dust. Also, those who insert commercially available universal lubricating oil into the keyhole when the key turns bad. There are many, but this should never be done with the latest precision keys. Immediately after inserting the key, the key will turn smoothly, but the lubricating oil and dust will mix and adhere to the keyhole part. This will lead to the cause of failure.

In key maintenance, it is important to first remove the dust from the keyhole. You can remove a lot of dust just by sucking it in with a vacuum cleaner or blowing it off with an air duster used to clean the keyboard of your computer.

Next, to clean the key body, first scrape off the dirt on the surface with a toothbrush, and then rub the grooves and dimples (holes) with a soft pencil. If you put it in the keyhole and turn it without wiping it off, graphite will adhere to the inside of the keyhole and act as a lubricant, and the key will turn surprisingly smoothly. I recommend 2B pencils with a soft core. "(Miwa Lock Public Relations Office Maki Kitani)

Also, even though it is said to improve slipperiness, candle wax and sewing machine oil are also NG. If you put the pencil lead directly into the keyhole, you will need to "disassemble and clean" to remove the broken lead, so it is important to follow the advice procedure. ..

I'm sure many people haven't had the idea of ​​"cleaning the keys" until now, but even if you don't have a special item such as an air duster or a non-oil, powder-type keyhole lubricant, you can use a vacuum cleaner, pencil, toothbrush, etc. You can easily do it with the one in. Moreover, it is said that "it is enough to do it once or twice a year", so it is a good idea to try it on a rock day or at the timing of general cleaning.

"Maintaining the correct key and being able to lock the door smoothly is the first step in crime prevention. In the summer, I feel open, I sleep with the windows open, and I say" a little to the neighborhood "without locking the door. , The number of people who go out will increase.

Just because it was okay until today, I don't know from tomorrow. Not only the entrance, but all the entrances and exits such as kitchen doors and windows are entrances for thieves. Be sure to lock it when you go out, and attach an auxiliary lock to the window when you open the window to ventilate. If you have built a new lock within about 10 years, or if you have not renewed the lock, replace it with a "CP certified lock" certified by the National Police Agency as having high crime prevention performance. I want you to review it. "(Mr. Saeki, mentioned above)
