How Locksmiths Make Keys Using Existing Locks

According to Wikipedia, locksmithing is the “science and art of making and defeating locks”. The traditional trade is also defined as one that requires locksmiths to complete an apprenticeship program in most parts of the world. Some countries ask for simple training certificates that are provided by employers, while others ask future locksmiths to get a full engineering school diploma while working as an apprentice for at least a few months before landing a job.

At the end of the training, no matter what they might incur, locksmiths will familiarize themselves with the nature of the job and know how to install a lock or cut a key using a lock, to mention just a few of the items on the job description list.

How Do We Cut A New Key Using A Lock?

The process involves several factors that our locksmiths will need to consider:

  • The current state of your lock
  • The brand and model of the lock
  • The number of keys you need

Solutions for cutting a new key based on a lock:

#1: Making A New Key Using Code

This is one of the simplest methods of cutting a new key. A key code is a key feature that allows a locksmith to make a duplicate that matches a lock without having to use the original key. There are two main types of key codes that lock technicians can use:

  • blind key code that requires computer programs for the translation of the blind code to a bitting code needed to cut the new key. The vast majority of key codes are blind codes. Codebook and code software publication are forbidden to licensed locksmiths in the majority of US jurisdictions for obvious security concerns. It is possible for locksmiths to make their own systems for blind key codes and thus identify and install key systems. Bling codes can also be used for vehicle locks; for example, X2100 is a Nissan blind code for creating an ignition key.

  • bitting key code that is normally located on the surface of the original key or on a card for high-security keys and locks. Bitting key codes are translated blind codes that will be used by the technician to cut the blank. This code is used along with the Depth and Spacing Number of the key in order to accurately determine the exact geometry of the key. The numbers that are part of the bitting code define the cuts found on the blade. A bitting code of 1111 with Depth and Spacing Number 46 refers to a Kwikset key that has four cuts. It is possible for a locksmith with rich experience to simply look at a photo of a key and know exactly what bitting code to use.

Locksmiths can use various code cutter models as the main key cutting tools when using bitting code to make a new key. The key blank needs to be inserted into the cutter in order for the process to be completed.

#2: Impressing An Old Key To Cut A New One

Whenever possible, a locksmith will use an old key to make a new key. The process does not require dismantling a cylinder. However, it is one of the most complex and complicated key making solutions as it incurs a lot of fine finishes and detailed work. In short, a key blank must be inserted into the matching lock so that the pins can be bidden into the cylinder. This will trigger the accurate sections to be repeatedly marked on the blank. This can be done with the help of pulling, tapping or other methods with the help of files, vice grips, and blanks.

Know some key banks tend to be sturdier compared to other models. For example, an aluminum key blank will crank faster, while a steep blank will be sturdier. The right amount of pressure must be used or else the process will be invalid and the locksmith will not be able to create a new key.

#3: Lock Disassembling

Whenever a locksmith is unable to make a new key with the help of code, they will try to disassemble the cylinder and reverse the bitting. If the wrong procedure is used, the lock can suffer irreparable damage. This is why it is important to only work with authorized locksmiths when making new keys for home, car or office locks.
