Key Duplication

Key Duplication is a process that requires an available “working key” to be copied. For example, in the incident you may need a spare key. The working key should be capable of operating the intended lock in order for the duplicated key to be successful. For this process, we select an appropriate blank key, which is then positioned in our key cutting machine to re-create the same specific cut patterns of the working key.

Key Cutting

Key cutting is the process used to create a new key by code number for when a working key is unavailable. A code is usually supplied with the original key or lock by the manufacturer when purchased. We then use this unique code number to identify the specific pattern of cuts required on a key to operate the lock it is used for.
