Mailbox Lock Services We Provide

Individual Apartment Mailbox Lock Replacement Lost your mailbox key, or is the lock worn and difficult to open? We replace the cylinder with a new lock and supply two new keys. Most standard apartment mailbox lock replacements take 15-20 minutes. We carry replacement cylinders for standard USPS-compatible and buildingspecific mailbox types.
Cluster Mailbox Lock Replacement Cluster mailbox units — the type with a master key for the mail carrier and individual locks for each tenant — require specific replacement parts. We stock replacement components for common cluster unit brands including Florence, Salsbury, and Auth-Florence. We can replace individual tenant locks as well as the carrier master key cylinder.
Building-Wide Mailbox Rekeying For landlords and building managers who need to rekey mailboxes after tenant turnover across an entire building, we provide volume mailbox rekeying at discounted per-unit rates. Contact us for a building-wide quote.
Mailbox Lock Repair If the lock is sticking, difficult to turn, or the key is becoming hard to insert, we assess whether repair or replacement is the better option. In many cases a worn cylinder can be serviced rather than replaced, saving cost.

Frequently Asked Questions

For individual apartment mailboxes in a building lobby, we often do not need access to the apartment itself — just the building. If you have a building superintendent or doorman who can let us into the lobby, we can complete the replacement without you needing to be present.

For most standard apartment mailbox cylinders, replacement is more cost-effective than rekeying. However, for higher-grade locks or situations where only the keys are the issue, rekeying is an option — see our Re-Keying Locks page for details.
