angerous criminals, gold bars, glittering jewels—what do they have in common? All are kept secure by locks and keys. Would the world be a happier place if no-one had invented such things? It just might be! • Imagine it for a moment. Anyone could steal anything, so perhaps no-one would bother owning very much or wanting anything more. No-one would live in a fancy house with valuable belongings, swan around in a luxury car, or earn more money than they could carry in their pocket. Perhaps that would be a better world, but it's not the one we live in! In our materialist modern age, we buy stuff, earn money, and buy even more stuff. We are what we own—and the only thing standing between a lifetime of slowly accumulated, valuable possessions and instant poverty is the lock on the door. Locks, then, are pretty important things, but have you ever stopped to wonder how they work? Let's take a closer look! • A commonly asked question is how does a key actually work? To answer, let’s first cover how the internal mechanism of a lock cylinder works. We will use a euro cylinder pin tumbler lock style as our example. This is a pretty standard type of lock that you are likely to find on the doors of your home. • Inside a pin tumbler lock there are – yep you guessed it, pins. Upper pins sit between springs and the pin tumblers. The spring and upper pins are fully extended and the pin tumblers are aligned inside the barrel of the lock. When a key is inserted into the lock they press against the pin tumblers forcing them into the upper chamber pins and compressing the springs. They pins are then pushed to align flush with the shear line. • The pins are designed to be different in height and configuration. These will match with the dents of the cuts on a correct key. When a key with a profile that matches the lock is inserted it aligns the pins correctly. This means that the shear line is clear of any pins in the way, which allows the key to turn. The cam which rotates to catch the bolt of the lock is triggered once the key has rotated the barrel. This rotation allows the lock to either unlock or lock. • How does one key work with multiple locks? • When locks are keyed alike it means the tumbler pins have been coordinated in the same way. If the pattern and size of the pins have been configured to be the same, one key is then able to operate each lock. • This is a very basic explanation of how keys work within a pretty standard lock and key system. The world of locks and keys is a complex one. Full of different locks, keys, and combinations to achieve the best security possible in any situation • क्या आपको पता हैं कि वे lock अंदर से काम कैसे करता हैं? चलिए बताता हूं लेकिन इस्से पहले इन चीजों के नाम बताता हूँ, ये हैं shackle और ये हैं locking bar और ये हैं plug, key pin, driver pin और ये हैं spring ये key pin का size के हिसाब से बड़ा या छोटा होता हैं। लेकिन ये ड्राइवर पिन की साइज बराबर होती हैं, और ये स्प्रिंग बड़े ही आराम से ऊपर नीचे होते हैं। और हम जब correct चाबी को इसमें लगाते हैं तो ये सारे पिन बराबर हो जाते हैं। यहाँ पर एक shear line open होती हैं जिसके कारण थोड़ा सा गैप बन जाता हैं, जिसकी वजह से हम चाबी को घूमा पाते हैं। और ये locking bar इस latch और spring की वजह से अंदर आता हैं। और उसके बाद ये बड़ी spring के कारण ये shackle ऊपर जाता हैं इसकी वजह से lock खुल जाता हैं। • ‪@AyEsciEncE_World‬ ‪@AyE_sciEncE‬
