True security begins long before a door is opened. It starts with who holds the key. Our restricted key systems provide complete control over duplication, distribution, and access, ensuring that only authorized personnel can reproduce or use your keys.
Designed for commercial, institutional, and multi-site environments, these systems use patented keyways and protected key blanks that cannot be copied without proper authorization. That means no off-the-shelf duplicates, no unauthorized copies, and no uncertainty about who holds access to your facility.
We design and maintain master key hierarchies that balance convenience and security, allowing multiple levels of clearance across departments, locations, and tenants. From a single building to a national portfolio, we tailor systems that provide trackable accountability and seamless integration with existing mechanical or electronic hardware.
Every restricted key program is supported by Top Door’s in-house key management protocols such as tracking issuance, replacement, and rekeying with precision. For facilities where turnover, compliance, or liability are concerns, restricted key systems deliver unmatched peace of mind.
Top Door offers complete key management and auditing services to maintain control across large or distributed sites. Our system logs every issued key, tracks holder assignments, and documents replacements or returns to reduce risk and streamline compliance for safety, insurance, and regulatory requirements.
We provide periodic key audits, secure record storage, and rekey scheduling to ensure your system stays current as teams change or facilities expand. Combined with restricted key technology, our management services help organizations maintain total visibility and eliminate guesswork in access control.
Because control isn’t just about keeping people out but about knowing exactly who’s in.
