Mailbox key duplication is the process of creating one or more copies of your existing mailbox key for backup or shared use. Whether you're a homeowner, apartment tenant, or business manager, having a spare key ensures you always have access in case of loss or lockouts.
Unlike standard door keys, mailbox keys—especially USPS-issued keys—require specialized blanks and cutting equipment. Not all hardware stores offer this service, but our mobile locksmith team in La Porte is fully equipped to duplicate keys for most mailbox types on-site. It’s fast, affordable, and reliable.
There are plenty of situations where an extra mailbox key comes in handy. You may have a roommate, spouse, or teenager who also needs access. Or perhaps you manage a property and want backup keys for tenants or staff.
Other reasons include:
It’s always a good idea to have a duplicate made before a key goes missing. If you’re unsure whether your key can be duplicated, just ask our tech during a mailbox lock replacement or install service.
Mailbox keys come in several types, depending on the kind of mailbox and who issued the lock. Each has different duplication limitations:
We work with all types and can help you determine which options are available based on your key and mailbox type.
In most cases, yes—if the mailbox is privately owned or under your responsibility. If the key belongs to a USPS-installed lock, federal law prohibits duplication. Instead, you must request a replacement through your local post office.
For all other types, duplication is usually legal and possible. We carry a wide selection of key blanks for older and modern boxes. We also ensure the duplicate is precisely cut to match the original so that it turns smoothly every time.
If you've lost your only mailbox key, don’t panic. Our mobile locksmiths can help by replacing the lock and issuing new keys. We’ll remove the old lock—even if it’s jammed or broken—and install a new USPS-compliant unit.
This is the best option for single-box owners or if you’re not sure who might have access to the lost key. If your mailbox is part of a larger unit, such as a cluster box, contact your landlord or HOA to coordinate replacement. We offer full service for cluster mailbox repair and installation if needed.
Duplicating a standard mailbox key is typically affordable. In most cases, the cost ranges from $10 to $25 depending on the type of key, the complexity of the cut, and whether we duplicate it on-site or in-shop.
Specialty or older key styles may cost a little more due to rare blanks or time-intensive cutting. However, if you've lost all keys and need to replace the lock, the service will include a new lock and key set. That usually runs between $55–$95, as detailed on our mailbox lock replacement page.
We always provide clear pricing before we begin. Whether it’s a quick key copy or full lock change, our La Porte mobile locksmith service gives you fast and affordable options with no surprise fees.
It’s important to know that not all mailbox keys can be legally duplicated. If your key is stamped "Do Not Duplicate" or belongs to a USPS-managed cluster box, it’s illegal to make copies. These keys are federally controlled and can only be replaced through USPS with proof of identity and address.
However, for personal mailboxes or those installed and managed by HOAs or landlords, you usually have the right to duplicate the key. Still, it’s good practice to notify your property manager or HOA before making copies, especially for shared community boxes.
We always respect federal and local regulations. If you’re unsure whether you can duplicate a key, just ask—we’ll help you determine the legal and proper solution for your specific mailbox.
