Safe Opening & Combination Change: comparing quotes
It depends on who still knows the old one.
New Tecumseth, Ontario · Locksmith · open 24/7

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.
Replacement lock or hardware needed
If the existing lock is worn out, damaged, or simply outdated, a replacement mechanical or electronic lock adds to the visit, priced separately from the opening itself.
Whether drilling turns out to be necessary
Manipulation, decoding and manufacturer reset paths are tried first; drilling, a repair plug and any replacement lock only enter the picture once those routes are exhausted.
Where the safe is located
A safe bolted to a floor, built into a wall, or set in a tight closet or basement corner takes more time to work around than one standing freely in an open room.
