Safe Opening & Combination Change: what the visit covers
Once a safe is open, the visit is only half finished.

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.
Mechanical dial or electronic keypad?
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.
Working a mechanical dial
A dial lock is read through the spindle rather than forced through it. The locksmith applies light, even tension and turns the dial slowly, feeling for the small changes in resistance that mark each wheel of the wheel pack falling into place, or uses a decoding tool built for that lock family to read the gate positions directly. Wear matters here: an older, well-used dial often gives clearer feedback than a newer one, while a dial that has drifted out of alignment over years of use may need the wheel pack itself adjusted once the door is open. Nothing about this process involves force on the dial or handle.
A little care keeps the lock reliable
A mechanical dial benefits from being turned through a full combination cycle occasionally even when the safe is not otherwise in use, since a dial left untouched for years is more likely to develop the stiffness that led to this visit. An electronic keypad benefits from a battery change on a set schedule rather than waiting for a low-battery warning to appear, since a dead battery at an inconvenient moment is the more common failure than the lock itself. Wiping the keypad and dial face of dust occasionally, without any liquid cleaner, keeps both types responding the way they should.
