Safe Opening & Combination Change: how the work is done
Changing a combination is not only for a safe that has stopped opening.
London, Ontario · Locksmith · open 24/7

Changing a combination is not only for a safe that has stopped opening. Businesses routinely have a working safe recombined the moment someone who knew the old code leaves, retires or changes roles, because a combination known outside the current staff is a loose end worth closing on its own. The visit is short when the safe already opens fine: confirm authority, dial or key in the old combination, set a new one, and test it before anyone signs off on the work.
What is inside and what timing matters
Contents shape how carefully an opening proceeds. Cash drawers, business records, prescription logs, jewellery or firearms each carry their own handling expectations once the door swings open, and the locksmith asks about them upfront rather than assuming. Business hours, an upcoming audit, or a room that needs to be usable again also factor into how the visit is planned, without changing which opening method is chosen. Knowing what is behind the door and what else is happening around the visit lets the locksmith sequence the work sensibly rather than working blind.
Drilling through a chosen, repairable point
When manipulation, decoding and the electronic reset path all fail to open the safe, drilling is explained to the owner before it begins, aimed at a specific point the lock manufacturer's own service documentation identifies as both reachable and safe to repair afterward. A borescope is used through the drilled hole to view the lock's internal parts directly and manipulate or bypass them without further damage. The aim is to affect nothing beyond that single hole, patched or plugged as one of the last steps of the visit, though the number of holes needed and any effect on the safe's rated protection level depends on its construction and is addressed with the manufacturer's approved repair method.
Giving more than one person a way in
Many electronic locks support more than one user code, which means a manager and a designated backup employee can each be set up with their own working code during the same visit, rather than the business depending on a single person again. A mechanical dial cannot offer separate codes the same way, but a documented plan for who holds the combination and how it changes when staff do serves the same purpose. Either way, the point is the same: this reset should be the last one caused by a single departure catching everyone else by surprise.
