A little bit of a milestone for Core Lock Services today. My first order of LG7 (GUILD 7) Restriced Master Key System stock has arrived! This will allow me to provide a higher level of security to customers who want to register their keys, that may only be cut by myself with an appropriate authorization. Multiple levels of access can be achieved through coding the locks and keys. The barrels are also more resistant to picking and the LG7 is patented until 2025! Pricing for this level of security will be developed so that it is affordable for both residential and commercial clients.
