Any commercial enterprise can be susceptible to risks such as unauthorized access and theft through unsecure doors. Protecting what you value most requires support and solutions tailored to your specific location, layout and vulnerabilities.
As industrial locksmiths, we serve the commercial sector with the services and equipment that give you greater control over comprehensive business security.
Commercial Doors
Doors at a commercial business can compromise security simply because they provide access to the premises. They can also involve a great deal of traffic. As but one example, main doors at a large manufacturing company can be opened more than one million times in a year. Beyond placing great wear on the doors, high traffic may also often create logistical issues such as proper key control.
By comparison, the back door of a small business or restaurant might be opened only a fraction as much, yet it can still pose a notable security risk. The key to protecting people and assets is having the correct commercial door for each application.
Citadel Lock & Security can partner with you to assess and discuss the condition and risks of your door and door opening. With a detailed understanding of each door’s function and usage, we can customize a security plan that may include commercial door repair, maintenance or installation, including commercial door frames.
Commercial Master Key Systems
Change is part of operating a business, as are events you cannot predict. Employees will come and go. Over time you will likely switch vendors, such as cleaning services. In some cases, you or another authorized person may lose a key.
Having a master key system gives you greater command of changes and events. It also provides a much better means of protecting people and assets. For example, if an employee leaves the business, you can ensure no duplicate keys exist and that access remains limited only to authorized personnel.
An electronic master key system will serve you in emergencies as well. With remote system access and tracking, you can respond immediately to specific areas of different locations of your business from wherever you are, even if you are out of the country. The system also keeps detailed records for monitoring, audits and investigations.
Because the locations are typically large and complex, master key systems are common at commercial operations such as hospitals, schools & colleges, warehouses, apartment complexes, transportation centers and government institutions.
Whether for a new or existing series of locks and doors, Citadel Lock & Security can partner with you in designing and installing a master key system that fortifies business security.
