Here is the inner identification from a high security Robur grade 5 safe. There had been issues with the time lock and the customer required new movements installing. Time locks are generally very reliable and faults are normally caused by the operator. Fortunately these safes don’t go wrong that often. If you have a safe equipped with either digital or mechanical time locks I can service and replace movements and complete units. They are not cheap items but provide the owner with another level of security for their safe.
