faqs About About Mailbox Lock Change
How do I know if my mailbox lock needs to be replaced?
If your key no longer turns smoothly, the lock is rusted or jammed, or you’ve lost your keys, it’s a good idea to have the lock replaced. This ensures continued access and security for your incoming mail.
Can you change the lock if I lost all my mailbox keys?
Yes. Even without the original keys, our technicians can safely remove the existing lock and install a new one. You’ll receive a fresh set of keys during the service.
Do I need permission to change my mailbox lock?
If your mailbox is part of a shared or USPS-owned unit, you may need approval from your property manager or the post office before replacing the lock. For privately owned mailboxes, no additional permission is usually required.
Is it possible to rekey the existing lock instead of replacing it?
Most mailbox locks are not designed to be rekeyed. In most cases, replacing the lock is the more secure and cost-effective option, especially if keys are lost or access needs to be changed.
