How to Duplicate a Key?

[PatrickRose]

Prepare the key that needs to be duplicated and place it over a lighter to create a blackened impression. Attach transparent tape to the blackened key, then transfer the tape onto a piece of sheet metal. Use scissors to cut along the key's shape and structure imprinted on the tape. Below is relevant information about keys: 1. Concept: Keys are commonly used unlocking tools in daily life, primarily made from metals such as copper, zinc, aluminum, iron, and others. 2. Classification: With advancements in automotive manufacturing technology, devices used to unlock car doors and start engines are collectively referred to as keys. Mechanical car locks are the most common and earliest form of car anti-theft devices, though they are rarely used alone in mid-to-high-end vehicles. Mechanical locks mainly serve to restrict vehicle operation and offer limited assistance in theft prevention, making them relatively easy to bypass.
