There are plenty of situations where having more than one mailbox key just makes sense. If you share your mailbox with a partner, roommate, or employee, it's best that each person has their own copy. Backup keys also come in handy if you’re traveling or want to store a spare in a safe place.
Many of our customers in Austin request duplicate mailbox keys during lock replacements, home moves, or after misplacing their first set. A simple key copy can help prevent lockouts and save you from having to replace the entire lock later on.
Mailbox keys vary depending on who owns the box and what type of lock is installed. Here are the most common key types we duplicate:
Always make sure you’re authorized to request duplicates for shared or managed mailboxes.
Yes—if the mailbox is privately owned or you're the registered keyholder, most mailbox keys can be copied using a professional locksmith. Some older keys may be harder to match at hardware stores, but we carry specialized blanks and can cut them with precision on-site.
For cluster boxes or mailboxes governed by an HOA, you may need to get permission or work through the property manager. We’re happy to coordinate with them on your behalf.
If you’ve lost your mailbox key and don’t have a copy, we recommend scheduling a mailbox lock replacement. Duplicating isn’t possible without an original. Our mobile locksmiths can unlock the box without damaging it, replace the lock, and give you brand-new keys on the spot.
Afterward, we suggest ordering at least one duplicate key to avoid being locked out again in the future. We can also help you secure your mailbox if you’re concerned about unauthorized access or mail theft.
The price for duplicating a standard mailbox key typically ranges between $10 and $25 per key, depending on the blank type and complexity. We offer discounted pricing for extra keys during service calls or lock replacements.
