There are plenty of practical reasons to duplicate your mailbox key. The most common is sharing access with a spouse, roommate, child, or tenant. It’s also smart to have a spare in case you lose the original key, especially if your mailbox is a cluster box or managed by an HOA, which may take time to respond to replacement requests.
Landlords, property managers, and Airbnb hosts often require multiple mailbox keys for incoming guests or maintenance teams. Having an extra key cut by a locksmith ensures it works smoothly and saves time dealing with unreliable hardware store machines. For added peace of mind, you can combine this with our lock replacement service if your box is aging or feels insecure.
Mailbox keys vary depending on the type of lock used. Here are the most common key categories we duplicate:
We also handle high-security and tubular keys depending on your setup. For more about cluster systems, check out our cluster mailbox services.
In most cases, yes—if you have the original key. Standard flat keys are easy to copy using a locksmith-grade key duplication machine. Just bring the working key to our technician, and we can create as many duplicates as you need on-site.
However, some mailboxes use restricted keyways or high-security locks, which may require special blanks or authorization to copy. If your key has “Do Not Duplicate” stamped on it, we can advise on your options or help replace the entire lock if needed.
If you’ve lost your mailbox key and don’t have a spare, the solution depends on who owns the mailbox. If it’s owned by USPS, you’ll need to request a lock change through your local post office. For privately-owned mailboxes, cluster boxes, or apartment mailboxes, we can help by opening the box and installing a new lock with new keys.
Our mobile team can access most locked boxes without damaging the unit. Afterward, we provide fresh keys and optional spares to prevent future issues. You can also explore security upgrades and anti-theft solutions in our mail protection section.
Mailbox key duplication is one of the most affordable locksmith services we offer. Prices typically range between $5 and $15 per key, depending on the key type. Flat metal keys are the cheapest, while tubular or security keys may cost more due to their specialized design and materials.
If you’ve lost the key and need a full lock replacement, expect a service fee and lock installation cost. Our technician will confirm all pricing before beginning any work.
It’s important to know who owns the mailbox and who has the right to duplicate keys. If the mailbox is USPS-owned (often found in single-family homes or rural areas), only USPS can authorize lock changes. Keys for these mailboxes usually cannot be legally duplicated.
However, if you own the mailbox or it’s part of an HOA or apartment setup where tenants are responsible for keys, then you can legally duplicate them. We advise checking your lease, HOA rules, or mailbox label before requesting duplication services to avoid legal complications.
