Locksmith in DavisvilleSafes opened,
combinations changed.

Yes. The visit closes with a written account of which door was opened and how, the condition the hardware was in, anything replaced, the number of keys cut and who received them. Landlords ask for it when locks on a unit change, insurers after a loss, and franchise head offices as a matter of course. Keep it with the lease; it also tells the next locksmith exactly what is on your doors.

Everything those keys fit. That usually means the front, back and side doors, the garage man-door, the mailbox and any padlocks, and in a rental the suite door with the landlord's involvement. Rekeying changes a serviceable cylinder to answer to a new key, and a cylinder that cannot be rekeyed is replaced instead. Doing every affected opening in one visit, keyed alike where the cylinders are compatible, means no forgotten door still answers to the stolen ring.

There is no fixed schedule; the sensible trigger is a change in who knows it, such as an employee or manager leaving, rather than a set number of months or years. A combination that has only ever been known to current staff generally does not need changing on a routine basis, since the lock itself does not wear out from correct use the way a mechanical part might.

An authorised person contacts the locksmith who holds your system, quotes the system reference, and the key is cut from code and numbered into the register. Some systems use a physical authorisation card, others an online validation, and business systems often require a signature that matches one on file. The key is collected or delivered, and the record shows the new total. It is deliberately not something a stranger with your key can do.
