The G7130 sash mortice lock is protected by the Banham Key Registration system. With our fully audited system, you can have peace of mind that you are in control of your keys. We will only copy keys for individuals registered or authorised in our key registration system, and we keep records of key cutting history to provide additional re-assurance for property owners. All new Banham locks and cylinders come with patent protected keys, meaning it is illegal for anyone else to make a physical copy of these keys.
