Mailbox Lock Change & Key Replacement

Best Types of Mailbox Locks

Upgrading your mailbox lock can dramatically reduce theft risk. Here are three high-security options commonly used:

• Cam Lock – A cost-effective basic option with key access, often used in traditional setups.
• Fort Knox Heavy Duty Lock – Ideal for high-risk areas; built to resist prying and drilling.
• Salsbury Cluster Box Locks – Used in USPS-approved cluster boxes; heavy-duty and durable for communal use.

Upgrading to a Secure Mailbox System

Consider replacing outdated mailboxes with tamper-resistant models that include advanced locks. We install both wall and post-mounted options built to USPS specs. Secure designs help protect mail from both thieves and weather damage.

Using Mail Hold and Informed Delivery Services

USPS offers “Informed Delivery” to digitally preview incoming mail. You can also request a mail hold during vacations. These services help you track deliveries and avoid overfilled mailboxes—an easy target for theft.
