If your mailbox lock is acting up, it’s better to replace it before it fails entirely. Some common signs include:
Ignoring a faulty mailbox lock could leave you locked out—or worse, make it easier for someone to steal your mail. We also recommend replacing your mailbox lock if you’ve recently moved or had your key stolen.

Our vans are stocked with key duplication equipment, lock extractors, and drills for emergency access. We always choose corrosion-resistant parts to ensure long-lasting performance, even in Austin’s humid climate.
Lost your only key? Don’t panic—we can unlock your mailbox without damaging it and then install a new lock with fresh keys. If your box is shared (such as in an HOA or apartment building), we’ll coordinate with management if needed.
For personal boxes, we recommend rekeying or complete mailbox lock replacement to eliminate any risk of old keys being used. We can also make you extra copies on-site for backup use.

If you’ve had break-ins in your neighborhood or use your mailbox for important financial mail, upgrading your lock is a small investment that delivers peace of mind.
