In-House and Hands-On



Letterbox Security

As a homeowner, you are likely already aware of the importance of locking the front door at all times to keep your family and home safe. You should invest in high-quality door locks for your home, but they aren’t the only thing you need to focus on. In addition to a strong door and reliable locks, you should also make sure that your letterbox is soundly secured. There is a growing number of burglars and criminals who take advantage of letterboxes in order to gain access to properties. Even though letterboxes are an essential part of many houses (after all, they make it easy for us to receive mail), they can put your home at risk if they’re not properly secured.

High-Security Letterbox Locks

You can replace the cheap mechanical lock on any mailbox with one of many high-security options at Stronghold Locksmiths. Depending on the needs of your business, we can provide you with many options to protect your mail.

Standard mailbox locks can be replaced with high-security locks such as:

  • High-security 5-pin tumbler lock replacement sets
  • Commercial-grade wafer locks
  • Combination of security turnkeys and padlocks
  • Cam locks with number combinations
  • Digital mailbox locks with keypads
  • Biometric mailbox locks (fingerprints) 
  • Smart-home locks with keyless entry

Additionally, we can upgrade the security level of your mailbox by replacing it with a durable heavy-duty stainless steel one. With high-quality hardware and components, we install, repair, and upgrade mailboxes. Our locksmiths can suggest the most appropriate mailbox locks for your mailbox based on the types and sizes of mailboxes you own. For example, a lock that works well on a standalone mailbox may not work well on a communal mailbox or multi-bank mailbox.

When your locking mailbox is broken, most postal carriers won’t drop your mail in there because it’s broken or full of mail. They usually attach a notice letter to the outside of the box. If your mailbox has a broken lock, anyone may be able to access your mail. It may also indicate that your key does not work with your lock. In such a situation, you need Emergency Locksmith in Brisbane to look into what is wrong with your mailbox lock. It might just be a matter of changing it out for a new one.

There are two keys included with each box. 

Letterbox burglary is when a burglar uses a letterbox on a front door to either break into a property or steal the keys inside (this could be to steal the car parked outside the property or to access the house). Generally, the burglar will either use their hand to push through the letterbox and reach up to unlock the door from inside the house, or they may use a fishing rod gadget with a hook on the end to ‘fish’ for keys left near the door.

Again, this depends: if it is a Cluster Mailbox, and you are the property manager or owner of the unit, then you can replace individual tenant locks, but only after the USPS mail carrier opens the master door for you.

For a mailbox lock replacement, you will need to:
  1. Request the change from the United States Postal Service (USPS) or your unit’s proper manager.
  2. When the post office changes your lock, you will receive a Delivery Notice Card on your doorstep. …
  3. Bring the card with you to get the new keys.
