Why cabinet locks fail
Most cabinets use small cam or plunger locks. Keys go missing, cheap cylinders wear, and drawers jam when the lock bar bends. Forcing a drawer often bends the frame and ruins the cabinet.
How a locksmith opens it
Many cabinet locks can be picked or decoded. Others are removed and replaced. A locksmith can usually cut a key to the existing lock or fit a new one so all your cabinets share a key.
Higher-security options
For cabinets holding personal data, checks or medical records, ask about high-security cam locks with restricted keys. Pair them with a key log so you know who has access.
Safes are different
Safes are built to resist entry. The price list notes that safe unlocking starts at $85.00 and involves damage, so the safe won't be usable afterwards. Ask about options first. See lock emergencies.
