- The call
- Decades of daily use have left the law firm's old dial safe drifting: the numbers line up close to where they should, never quite enough to drop the bolt.

Once a safe is open, the visit is only half finished. The lock is inspected for wear, corrosion or damage that caused the original problem, repaired or replaced if it is no longer reliable, and then set to a new combination chosen on the spot. That combination is cycled several times with the door both open and closed so everyone leaves confident it will work again on the next ordinary morning, not just once under supervision.

Safe Opening & Combination Change · Harmony Hall II

Scene 1
The two lock families are opened in entirely different ways, so telling them apart comes early. A mechanical dial relies on a wheel pack turned into alignment by hand, reading resistance and feel rather than any battery or circuit. An electronic keypad instead depends on a stored code and a power source; some models add a reset or override sequence, though many need that connection made at the lock body inside the container rather than from outside. Some commercial safes carry both, a keypad for daily use with a mechanical dial as a backup, and each half is assessed on its own terms. Confusing the two wastes time trying an approach the lock was never built to respond to.
Scene 2
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.
Scene 3
Every old credential the lock supports, past user and manager codes, any super-master or recovery code, keys and external access, is checked and removed rather than just the one combination in daily use, so nobody still holding an old way in, a departed employee, a previous owner or otherwise, keeps one. The new sequence is chosen by the current owner or manager on the spot, not assigned from a list. This is worth treating deliberately rather than casually: deciding who genuinely needs the combination, and keeping that group as small as the business actually requires, is the simplest way to keep a fresh reset from becoming next year's same problem.

It depends on who still knows the old one. If a bookkeeper, manager or previous owner who had the combination is no longer with the business, resetting it closes that gap even though nothing about the lock itself has failed. A safe that only the current staff have ever known the code to generally does not need changing on that basis alone.
Each suits a different way of working. A mechanical dial has no battery to fail and a long service life, but only ever holds one combination at a time. An electronic keypad allows separate codes for different staff and an audit trail on some models, at the cost of needing battery changes. Either can be fitted with a genuinely high security rating; the choice usually comes down to how many people need independent access.
It can. Heat or water exposure sometimes trips a relocker or damages the bolt work independently of the combination lock, so the locksmith checks for that first rather than assuming the lock itself has failed. A safe with fire-rated insulation may also need that lining checked once open, separately from the lock work.

The pharmacy's drop safe has a keypad that finally lost power for good, and the little override key that was supposed to live behind the counter cannot be found anywhere.
