Restricted master key systems:
CSM Locksmiths specialise in the implementation of restricted master key systems. Restricted master key systems are perfect for businesses, especially those with multiple departments.
A restricted master key system provides a high level of control and security. At CSM Locksmiths, we manage each system, requiring written, signed authorisation from an approved individual – usually the business owner or manager – before cutting any additional keys.
No other locksmith can duplicate these keys, ensuring maximum protection against unauthorised copies. This increases security and prevents unauthorised duplicate keys being cut.
All restricted keys are identified with system numbers and key issue numbers, so it is easy to keep track of the total amount of keys cut for your business.
