Can I duplicate a mechanical key myself?

[LeElle]

Ordinary mechanical keys can be duplicated by yourself. However, high-end car keys with built-in chips must be duplicated at a professional 4S store. Here are specific details about automotive mechanical keys: 1. Function: When the button battery in the key runs out of power and you cannot unlock or lock the doors, you can use the mechanical key for emergency unlocking or locking. Some vehicles also allow starting the engine with the mechanical key. 2. Technological Innovation: Advances in technology have driven product updates, shifting the entry system from traditional mechanical keys to remote control systems. With the widespread application of mature technology and the demands of the automotive market, it has become an inevitable trend for keyless entry systems to replace remote entry systems.
