Secure home delivery system

A system for providing secure delivery or collection of goods too large to be delivered through traditional apertures such as the letterbox, to a location, such as a home, where the goods have previously been remotely ordered using some remote means such as the internet or telephone. Access to a secure location, for example, a dedicated receptacle, garage or shed, is achieved by presentation of an access code by the delivery personnel, the origin of which is linked to the order of the goods. The access code may be computed using time-based algorithms that are replicated by the lock at the delivery location, unlocking occurring when the access codes coincide. The lock can provide access to a key safe, which in turns holds keys that provide access to a secure location. The system could equally be used for the collection of goods and for providing access to utility meters.
