Safe Deposit Locks

Safe deposit locks are a cornerstone of secure storage in financial institutions, private vault facilities, and high-trust environments such as law firms, medical offices, and estate management services. These locks are specifically designed for controlled, dual-access storage—ensuring that both the institution and the box holder are involved in the access process, which helps prevent unauthorized entry and strengthens accountability.

At Bay Safe & Lock, we specialize in the supply, installation, and service of safe deposit locks, offering high-quality solutions tailored to banks, credit unions, legacy vault rooms, and emerging private storage facilities.
 

What Is A Safe Deposit Lock For?
Safe deposit locks serve a unique function: they offer two-key control, requiring one "guard key" held by the institution and one "renter key" held by the box holder. This system ensures that:

• No single party can access the box alone, enhancing client confidence and institutional liability protection.

• The locks are designed to be highly pick resistant, forcing any malicious party to resort to destructive entry methods which are loud and time consuming.

• Their compact design and tamper-resistant construction make them ideal for densely packed safe deposit cabinets in vault environments.​

 

What Bay Safe & Lock Provides

• Complete Lock Supply
  We can source safe deposit locks from all major manufacturers, including S&G, Diebold, Mosler, and LeFebure. We can also usually find legacy and hard-to-find models.

• Professional Installation
  Whether you’re outfitting a new vault or replacing worn or malfunctioning units, our team ensures precision alignment, secure mounting, and proper cylinder seating—critical for dual-key systems to function correctly.

• Ongoing Service & Rekeying
  From routine servicing and lubrication to renter key changes and forced openings (when a renter has lost access or moved without returning the key), Bay Safe & Lock provides full-cycle care. We also offer key duplication.

• Emergency Box Access
  If a box is jammed, misaligned, or missing one or both keys, we can non-destructively open the unit, repair or replace the lock, and document the entry in accordance with your institution’s procedures.
