What Codes Can Yale Lock Hold? User Limits Explained

Yale locks are known for their advanced security features and user-friendly interfaces. One of the key aspects of Yale locks is their ability to hold multiple codes, which can be useful for granting access to different individuals or groups. In this article, we will delve into the specifics of what codes Yale locks can hold and the user limits that apply.
Understanding Yale Lock Codes

Yale locks use a combination of numeric codes and user IDs to control access. Each user can be assigned a unique code, which can be a combination of numbers, letters, or a combination of both. The length of the code can vary depending on the specific lock model, but most Yale locks support codes ranging from 4 to 8 digits. The codes are stored in the lock’s memory, and the lock can be programmed to recognize and respond to specific codes.
Code Capacity and User Limits
The number of codes that a Yale lock can hold varies depending on the model and series. Some of the most common Yale lock models and their code capacities are:
Lock Model | Code Capacity |
---|---|
Yale YDM 4109 | Up to 20 user codes |
Yale YDM 7116 | Up to 30 user codes |
Yale YRD220 | Up to 25 user codes |
Yale YRD410 | Up to 20 user codes |

It's essential to note that the code capacity can be affected by the lock's memory and the complexity of the codes. More complex codes, such as those that include letters and numbers, may take up more memory than simple numeric codes.
User Management and Code Administration
Yale locks provide various features for managing users and codes. These features include:
- Code creation and deletion: Admin users can create and delete codes as needed, ensuring that only authorized individuals have access to the lock.
- Code editing: Admin users can modify existing codes, which can be useful for updating user information or changing access levels.
- Code expiration: Some Yale locks allow admin users to set expiration dates for codes, which can be useful for granting temporary access to visitors or contractors.
Yale locks also provide features for monitoring and tracking code usage. These features can help admin users identify and address potential security issues, such as unauthorized access attempts or code sharing.
Best Practices for Managing Yale Lock Codes

To ensure the security and effectiveness of Yale lock codes, it’s essential to follow best practices for code management. These best practices include:
- Use complex codes: Use a combination of numbers, letters, and special characters to create complex codes that are difficult to guess.
- Limit code sharing: Avoid sharing codes with multiple individuals, as this can increase the risk of unauthorized access.
- Regularly update codes: Regularly update codes to ensure that only authorized individuals have access to the lock.
- Monitor code usage: Regularly monitor code usage to identify and address potential security issues.
By following these best practices, users can help ensure the security and effectiveness of their Yale lock codes.
