There are several reasons why a key cylinder on a commercial storefront door might need replacing.
Lost or Stolen Keys: If you lose keys or suspect someone unauthorized might have a copy, ensure they won’t be able to access your store.
Damaged Cylinder: A broken or malfunctioning cylinder can compromise security and leave your store vulnerable.
Employee Turnover: As employees come and go, replacing the cylinder ensures control over who has access to the store. 
Upgrading Security Features: Newer key cylinder models might offer improved security features like bump-proof mechanisms or higher pick resistance.
Wear and Tear: Over time, frequent use can cause the cylinder to become worn or jammed, making it difficult to operate with the original key.
