There may be times when you need your digital lock to have a mechanical back-up due to loss of codes or intentional tampering. The redundant mechanical option offers such a feature. Consider the following:

Safes in Remote Locations
If you have a heavily used safe in a remote location you will not have access to immediate support from your locksmith in the case of a problem. For example, a mine in far Western Australia uses a quality safe for the storage of gold bullion. If they have a lock-out situation, the nearest locksmith is about 48 hours away. The redundant mechanical option gives the mining company peace of mind.

Bank Vaults and Ultra-Heavy Duty Safes
In the case of bank vaults and ultra-heavy duty safes, a lockout is a very serious, costly and time-consuming problem to solve. As a back-up, owners of these vaults and safes choose the redundant mechanical lock option.
