Key copying presents obvious security risks, because key duplication can happen without your knowledge. A tenant, contractor, or visitor might make a copy of a key and retain access long after their permission has expired. This can lead to things like, unauthorised entry, theft or vandalism, compromised privacy and increased liability for property owners.

According to smart lock specialists Iloq, this is why choosing a key system that physically or digitally prevents copying is essential.

Some types of keys and key systems are designed so that they cannot be copied, or at least are very hard to dublicate for example: 

• Restricted key systems: These use patented keyways that can only be duplicated by authorised locksmiths with proper documentation.

• High-security mechanical keys: Some brands offer keys with complex designs and legal protections against unauthorised copying.

• Electronic access cards and fobs: These can be programmed and deactivated remotely, making them secure and flexible.

• Smart keys: These digital keys offer advanced encryption and secure authentication methods, reducing the risk of unauthorised access and duplication.

Smart keys, like those from Iloq, are not just physical objects – they are encrypted digital devices that use secure authentication protocols, and offer more security for the following reasons:

• Physically identical: Unlike traditional keys, smart keys look the same are and mechanically identical. This means there’s no point in copying them.

• Unique digital identity: Each Iloq smart key has a unique digital identity programmed into its microchip. These digital credentials control to where the key has access.

• Encrypted communication: Each key communicates securely with the lock to verify its access rights.

• Remote management: Access rights are remotely and instantly programmed, updated and revoked using Iloq’s software to keep access rights up to date. When no longer needed in one locking system, the keys can conveniently be reprogrammed and reused in another locking system.

• Audit trails: These chronological logs, that record all activities within an Iloq locking system, provide a detailed history of who accessed what and when. These trails are crucial for security, compliance, transparency, accountability and troubleshooting, allowing administrators to monitor usage and identify potential issues.

Enhanced control and peace of mind

Opting for a smart-locking solution with keys that can’t be copied offers peace of mind and enhanced control over your property. The benefits are varied depending on the application, for example:

• Apartment buildings: Prevent unauthorised access to keep homes and their contents safe. Simplify key management and eliminate the risk of copied keys floating around.

• Commercial properties: Protect sensitive areas and reduce the risk of internal breaches.

• Schools and public institutions: Ensure only authorised personnel can access, for example, restricted zones.

• Critical infrastructure sites: Ensure only authorised technicians have access to the right sites at the right times to keep the infrastructure operating reliably.

According to Iloq, selecting a smart-locking solution with keys that can’t be copied,  demonstrates a commitment to investing in long-term security, reducing liability, and ensures that access to the property is properly controlled.
