Abstract
The present invention relates to electronic and mechanical dual combination locks. In certain embodiments, electronic and mechanical dual combination locks include: a lock base, a spin dial, a spin dial cover, and a spin dial release conversion mechanism. The lock base includes a mechanical combination lock inside. An electronic combination lock is positioned inside the spin dial cover. The spin dial release conversion mechanism has a spin dial release positioned on the top of the lock base. The spin dial release is used by the user to switch the electronic and mechanical dual combination lock between the electronic combination lock and the mechanical combination lock. When spin dial release is placed in a first position, the electronic and mechanical dual combination lock becomes the electronic combination lock. When the spin dial release is placed in a second position, the electronic and mechanical dual combination lock becomes the mechanical combination lock.
