Whether you have a private wall-mounted box, an HOA-managed cluster unit, or an apartment mailbox, we offer professional key duplication services throughout Round Rock and nearby areas.

Our mobile locksmiths come to you with advanced tools to copy most common mailbox key types on-site. Avoid mail access issues and the hassle of lost keys—get your spares made the right way, with local service you can trust.



Reasons You May Need a Duplicate Key

Duplicating your mailbox key is one of the simplest ways to avoid lockouts and keep access convenient for multiple users. Here are some common situations where getting a duplicate key makes sense:

  • You want to share access with a spouse, roommate, or property manager
  • You’re a landlord preparing a unit for a new tenant
  • You want to keep a backup copy in a secure place
  • You’re worried about losing the only key you have

For multi-unit mailboxes, especially in HOA or apartment settings, duplicates are often required. If you're managing a cluster mailbox unit, we can provide sets for each individual box on-site.

Types of Mailbox Keys

Mailbox keys come in several varieties depending on the mailbox type and delivery method. We regularly duplicate the following:

  • Private mailbox keys: Most post-mount and wall-mount boxes use simple cam lock keys that are easily duplicated.
  • HOA or apartment mailbox keys: Often use commercial-grade locks, and we provide duplicates that match your master system.
  • Cluster box unit (CBU) keys: These are commonly found in newer subdivisions and managed by HOAs or USPS delivery. We handle non-USPS units only for duplication unless authorized.
  • USPS arrow keys: These cannot be duplicated legally. Only USPS can provide or manage these keys.

Not sure what type you have? Call us and we’ll identify it during your appointment or during a lock replacement visit.

Can You Duplicate Your Existing Mailbox Key?

In most cases, yes. If your key is a standard single- or double-sided cut (like most cam locks), it can be duplicated easily. Our mobile locksmiths can duplicate your key using precision-cut machines that ensure a smooth fit.

However, high-security keys or keys marked "Do Not Duplicate" may require proof of ownership or authorization. Contact us if you're unsure, and we’ll help determine the right solution.

What to Do If You Lost the Original Key

If you’ve lost your only mailbox key, don’t worry. We offer mobile service to safely open your mailbox and replace the lock. Once the new lock is installed, you’ll receive a fresh set of keys—and we can duplicate more on the spot if needed.

Trying to force your mailbox open or drill the lock yourself can cause damage. Instead, rely on our professional tools and techniques to do it safely and legally. If your mailbox was tampered with, learn more about mail theft risks and prevention.

Costs of Mailbox Key Duplication

Our mailbox key duplication service is affordable and quick. Here’s what you can expect:

  • Standard mailbox key copy: $5–$15 per key
  • High-security key (if supported): $15–$25 per key
  • On-site duplication during lock replacement or repair: $5 per key

We also offer discounted bundles when copying multiple keys at once. During your post-mount mailbox installation, ask us to create a full key set for all users.

Before duplicating a mailbox key, it’s important to understand who has the right to do so. If you’re a tenant, you may need permission from your landlord or property manager. If you're replacing or copying HOA-managed keys, they may require registration or oversight.

We follow all legal guidelines and may request ID or documentation for certain lock types. We never duplicate USPS arrow keys or restricted master keys unless explicitly authorized.

If you're unsure whether you’re allowed to duplicate your key, give us a call and we’ll help walk you through it. Our goal is to help you stay safe and compliant.

Frequently Asked Questions
