Unlocking skills and safety precautions of chain lock
Introduction:
In daily life, chain lock is a common anti-theft tool, which is widely used in the safety protection of bicycles, motorcycles and other items. However, in some specific cases, such as forgetting the key or accidentally losing it, we have to face the problem of how to open these locks. This article will introduce some simple unlocking skills of chain locks and corresponding safety precautions for you.
First, the unlocking skills:
1. The locksmith tool method:
The locksmith's tool is a special tool used to open various locks, including chain locks. When using the locksmith's tool, it is first necessary to find the position of the lock core and insert it into the lock hole; Then try to unlock it by rotating it until you feel the lock is loose. However, it should be noted that this method needs a certain technical foundation and practical experience to complete.
2. The key copy method:
If you have a spare key but no original key, you can consider this method. The specific operation steps are as follows: first, polish the newly bought ordinary blank key with a file to make it similar to the original key; Then use this imitation "fake" key to try to open the chain lock, and sometimes it is unexpectedly successful.
3. Disassembly method:
The disassembly method is suitable for some types of chain locks with relatively simple structure and easy disassembly. Its basic principle is to achieve the purpose of unlocking by destroying or removing some components. For example, for those chains with only one-way bayonet design, we can pry up the shell with a screwdriver first, and then press down the internal spring to easily take out the bolt.
4. Electromagnetic interference method:
Electromagnetic interference method refers to one of the methods to make the electronic control module produce wrong instructions by using high-frequency pulse signals so as to achieve the effect of opening the door. This method is usually only applicable to the chain lock products with intelligent digital cipher disk, but it is ineffective for the traditional mechanical structure.
5. Hot melt method:
The hot-melt method mainly attacks the shell parts made of plastic materials. After the shell is softened and deformed by heating, it is forcibly squeezed in by external force, and finally the locking mechanism loses its function and automatically pops up.
6. Grinding method:
For some products made of low-strength metal materials, direct violence can be used to demolish them destructively. For example, using an electric tool such as an angle grinder or an electric drill, under the premise of ensuring its own safety, it cuts through at a fast enough speed, so as to achieve the purpose of quickly unlocking the chain lock.
Second, the safety precautions:
Although some of the above-mentioned unlocking skills can help you solve the problem in an emergency, we strongly recommend that you do the following safety precautions at ordinary times:
1. Buy locks with reliable quality;
2. Check and maintain your locks regularly;
3. Don't place valuables in public places at will;
4. Try to choose high-tech anti-theft equipment with alarm function;
5. Improve personal alertness and risk awareness.
Conclusion:
Although I have mastered some unlocking skills, I can really provide them when I encounter difficulties.
Convenience and support, but more importantly, we should strengthen our own security capabilities and avoid unnecessary losses from the source. I hope this article can help everyone!
