A regular key opens only the specific lock it was cut for. A master key is engineered to open multiple locks within the same system, while each lock can still have its own individual change key. This lets business owners or managers access any door while restricting staff to only the areas they need.

After a break-in, the professional priority is replacing or rekeying any compromised locks and repairing damaged door hardware. A commercial locksmith can also assess your entry points and recommend upgrades — such as high-security lock cylinders, reinforced strike plates, or access control — to reduce the risk of a repeat incident.

In most cases, yes. Rekeying changes the internal pin configuration of an existing lock cylinder so old keys no longer work, without replacing the lock body itself. This is significantly cheaper than replacement and is the recommended first step after staff turnover, a lost key, or moving into a new commercial space.

Most standard lock and deadbolt installations don't require a permit. However, some access control systems — particularly those integrated with fire or alarm systems — may require coordination with your building's fire marshal or a licensed electrician. Arch City Locksmith will flag any compliance considerations before work begins.
