Keys are an essential part of our lives, granting us access to our homes, offices, and vehicles. However, in our fast-paced and convenience-driven society, it’s not uncommon for individuals to make copies of copies of standard keys. While it may seem like a simple solution at the time, this practice can lead to a range of problems and security risks. In this blog post, we’ll delve into the issues surrounding the act of making copies of copies of standard keys and why it should be avoided.

Loss of Key Integrity

Each time a key is copied, there is a loss of key integrity. Standard keys are designed to fit precisely into locks, ensuring smooth operation and reliable security. However, when a key is duplicated, even once, the new copy may not be an exact replica of the original. Minor imperfections, variations, or wear and tear can accumulate with each subsequent copy, resulting in keys that are increasingly prone to malfunctions or breakage. The reduced integrity of these copies can lead to frustrating experiences and compromised security.

Increased Vulnerability to Unauthorized Duplication

Copying a standard key multiple times exponentially increases the risk of unauthorized duplication. While reputable locksmiths and key duplication services employ strict protocols to ensure the legitimacy of key copying, each additional copy increases the chances of a key falling into the wrong hands. Unauthorized copies can be made without the knowledge or consent of the key owner, potentially leading to security breaches and unauthorized access to personal or confidential spaces.

Security Risks in Master Key Systems

In settings where master key systems are in place, the issue of making copies of copies becomes even more problematic. Master keys grant access to multiple locks, offering convenience and ease of use for building owners and managers. However, the security of such systems relies on the limited distribution and controlled duplication of master keys. Making copies of copies dilutes the control over the key distribution, increasing the likelihood of unauthorized access, compromised security, and potential legal consequences.

Weakening of Key Control Measures

Key control measures, such as restricted keyways or patented key systems, are designed to enhance security by limiting unauthorized key duplication. However, making copies of copies undermines the effectiveness of these measures. Even if the original key was part of a high-security system, subsequent copies may not retain the same level of protection, leaving critical areas more vulnerable to unauthorized access.

Financial Implications

The practice of making copies of copies can have financial implications. Repeated key copying can lead to more frequent lock replacements, repairs, or even entire lock system overhauls. The costs associated with these measures can be substantial, and in some cases, the security breaches resulting from compromised keys can lead to significant losses, both monetary and in terms of personal or professional reputation.


While it may be tempting to make copies of copies of standard keys for convenience’s sake, it’s crucial to recognize the potential problems and security risks associated with this practice. Loss of key integrity, increased vulnerability to unauthorized duplication, weakened key control measures, and financial implications all highlight the need to approach key copying with caution. Whenever possible, it is advisable to obtain duplicates directly from authorized locksmiths or key duplication services using the original key, ensuring the highest level of security and peace of mind.
