There are several methods of key topography

There are several methods of key topography, and you can choose the right one for your specific situation:

1. Traditional key topography: this is one of the most common methods. The original key is placed on a key topstitching machine and a special tool is used to topstitch the key outline from the side onto a piece of soft metal material. The metal topography is then duplicated into a new key using a key duplicate making machine.

2. Digital Image Scanning: In recent years, with advances in technology, some specialized key stores use digital image scanners to create a digital image of a copy of the original key. The computer software is then used to make a copy of the key without the need to physically make a topography.

3. QR Code Topping: Some modern key stores use QR code technology to encode the information of the original key onto a QR code. The QR code is then scanned into a key copy making machine, which creates a new key based on the QR code information.

It should be noted that key-topping requires a certain degree of expertise and equipment, so it is recommended to find a professional key store or locksmith company to operate. In addition, key printing involves security issues, please make sure that the use and storage of the key is safe to avoid potential risks.
