A business owner's guide to locks and key control

Even a small business can end up with dozens of keys in circulation. Good key control keeps you secure without slowing anyone down.

Do I need a locksmith if my locks work?

Working isn't the same as secure. If former staff still have keys, if anyone can copy your keys at a hardware store, or if your back door has a basic residential lock, it's worth a review.

Master key systems

A master key system lets managers open every door with one key while each staff member's key opens only what they need. When someone leaves, you rekey the affected cylinders rather than the whole building.

Restricted and high-security locks

Restricted keyways can't be copied without your authorization. High-security cylinders resist picking, bumping and drilling. Both suit server rooms, stock rooms and anywhere cash is kept.

Doors and hardware

  • Emergency exit devices that meet code and still lock from outside
  • Heavy-duty deadbolts and strike plates on rear doors
  • Door closers that make sure doors actually latch
  • Keypad or card access for doors many people use

Records and cabinets

Locking file cabinets and desks protect client and employee information. See file cabinet lockouts and keyless entry.
