Residential And Commercial Mailbox Lock Services-
Master Locksmith

  Although there are still some Commercial Mailboxes without built-in or external locks, the bulk of Commercial Mailboxes are locked. We are accustomed to seeing powerful, heavy-duty built-in locks on the majority of Commercial Mailboxes due to the sensitive nature of business paperwork, cheques, banking statements, and credit information. Personal Mailboxes are the same way.

Traditional or Residential Mailboxes, which do not have locking devices, are significantly more popular in single-family residences. Mailbox Locks are more common in an apartment, condominium, and townhome developments. Our Mailbox Lock Locksmiths can assist you regardless of whether you are locked out of a commercial or residential mailbox.

"Can a Mailman open my Mailbox for me"?

The answer is no. In fact, letter carriers are not allowed to carry a key for residential mailboxes. Most USPS approved residential curbside locking mailboxes work in the same basic way as an unlocked curbside mailbox. The postal officer deposits your mail through an incoming mail door or slot.

"How do you unstick a mailbox lock"?

Repeatedly heat the keyhole and the key, holding it under the hair dryer for 20 to 30 seconds. Try the key in the mailbox until the ice loosens and you are able to work the lock. Do not force the key into the lock, or force the key to turn, as this can cause your key to break.

"What do I do if my Mailbox won't open?"

Go in person to the post office for your address. It’s possible the apartment complex owns, and is responsible for, your mailbox. The postal clerk will let you know. If it’s a USPS mailbox and your key no longer works, you can get a new lock & keys installed free of charge.
