Mailbox Lock Change & Key Replacement

Need a spare mailbox key in League City? Whether you're managing rentals, living in an apartment, or just want a backup, Mailbox Lock League City makes key duplication quick, easy, and secure. Our experienced locksmiths are mobile and ready to duplicate most mailbox keys on the spot, including USPS-approved and HOA-issued keys.


Introduction to Mailbox Key Duplication

Mailbox key duplication is a common request we handle daily at Mailbox Lock League City. Whether you're a homeowner, renter, or property manager, having an extra key is essential to prevent lockouts and ensure access when you need it. We specialize in fast and reliable duplication of a wide range of mailbox key types.

Our mobile locksmiths come directly to your home, apartment complex, or commercial property in League City. We can duplicate most standard and custom mailbox keys on-site. If you've lost your key, we can also rekey or replace the lock entirely.

Reasons You May Need a Duplicate Key

Here are some of the most common reasons customers in League City call us for duplicate mailbox keys:

  • You want a backup key in case of emergency
  • You're sharing the mailbox with family or roommates
  • You’re managing a rental property or commercial unit
  • You want to avoid being locked out

With so many reasons to duplicate your mailbox key, it's best to act before the original is lost. We also recommend considering secure lock upgrades at the same time.

Types of Mailbox Keys

Mailbox keys vary based on the mailbox type and whether it is managed privately or by a federal or housing authority. We duplicate:

  • USPS Arrow Keys: Only duplicated by USPS—if lost, you'll need a lock change.
  • Private Box Keys: Often found in residential mailboxes. We duplicate most standard models.
  • HOA-Managed Cluster Boxes: HOA may provide original, but we offer replacements and lock swaps if needed.
  • Apartment Mailbox Keys: Common in vertical or wall-mounted styles—easy to duplicate when permitted.

If you're unsure which type you have, our technicians will identify it during the visit.

Can You Duplicate Your Existing Mailbox Key?

Most privately issued mailbox keys can be duplicated without issue. We carry blank keys for common locks used by manufacturers like Florence, Salsbury, and Mail Boss. However, if the key is marked “Do Not Duplicate” or managed by USPS, duplication may not be legal or possible.

We advise you to contact us so we can check your specific key and provide the right solution, which may include a lock change.

What to Do If You Lost the Original Key

If you’ve lost your only mailbox key, we can help. Our team can either create a key by code (if the lock is accessible and marked), or we can remove and replace the mailbox lock completely. If your mailbox is managed by an HOA or USPS, you may need to notify them before we proceed.

Explore our full lock replacement service if needed, or check your unit for a key code label to speed up the process.

Costs of Mailbox Key Duplication

Pricing depends on the mailbox key type, duplication method, and whether a lock change is needed. Here's a breakdown of estimated costs:


Service type Price
Service Call $29
Standard Mailbox Key Duplication $7–$15 per key
On-Site Lock Identification and Key Matching $25–$40
Lock Replacement if Key Cannot Be Duplicated $45–$85

All pricing is approximate. Your technician will provide a final quote before beginning any work.

Mailbox keys are often considered federal or property-specific items. If you live in a managed community or your mailbox is part of a centralized unit, duplication may require approval from a property manager or HOA. USPS keys cannot be duplicated under federal law.

We always verify legal authority before duplicating. When in doubt, we’ll offer a lock replacement solution instead. For more info, read our article on mail theft and identity fraud prevention.
