Key Blanks | Key Cutting

Key blanks are uncut, standardised keys designed to fit specific lock types. They serve as the foundation for creating a functional key through a cutting process that matches the internal mechanisms of your lock, allowing for secure access.

To identify the right key blank, start by noting the lock brand and model if possible. Look for distinguishing features such as the shape of the key’s head, the length of the blade, and the positioning of any grooves or notches. This helps ensure you select a compatible blank key for cutting that will work seamlessly with your lock.

Key blanks are typically manufactured from metal alloys, such as brass or nickel silver, chosen for their durability and corrosion resistance. They are stamped or cut into a standardised profile, ready for further cutting to match individual lock patterns.

These blanks are primarily used by locksmiths and DIY enthusiasts to produce new keys or duplicates. From mortice key blanks for traditional British locks to specialised blanks for modern locking systems, they enable efficient key replacement without the need to change the entire lock.

Mortice key blanks are specifically designed for the internal locking mechanism of mortice locks, often found in traditional doors. They offer a secure fit and precise alignment with the lock’s levers, ensuring smooth operation and enhanced security.

No, a blank key cannot open any lock on its own. Because it lacks the specific cuts or ridges that align with a lock’s internal mechanism, a blank key will not fit perfectly or release the lock. It must first be cut to match the unique pattern required by that lock before it can function.

While some homeowners opt for DIY cutting, achieving accurate results typically requires specialised equipment (Key Cutting Machines) and expertise. For the best outcome—and to avoid damaging the lock—it’s recommended to visit a professional locksmith or a well-equipped key-cutting service.
