Exploring Top Methods: From Prying to Locksmith Solutions

Understanding Mailbox Lock Security

Delve into the world of mailbox lock security, ranging from low-tier protection to the illusion of fortress-like strength. Uncover the reasons behind the rarity of high-security locks on mailboxes and why basic techniques often breach these supposedly secure barriers.

Unlocking Apartment Mailboxes: The Strategic Approach

1. Property Manager’s Key Magic

For those dwelling in rented spaces, a potential solution lies with your property manager. Reach out for a spare key, assuming you haven’t changed the locks without notifying the manager. Even if no spare key is readily available, your property manager can guide you on opening the mailbox without a key.

2. Contacting USPS for Control

In cases where the mailbox falls under the jurisdiction of the United States Postal Service (USPS), reach out to your local office. While the infamous USPS Form 1094 seems elusive, your local postal office can provide instructions on obtaining a key. Never underestimate the power of communication before attempting independent mailbox lock exploits.

Key Takeaways:

  • Property managers may hold spare mailbox keys.
  • Contact USPS for mailbox lock guidance.
  • When spare keys are unavailable, seek advice from these resources.

1. Prying: Swift Entry with Careful Force

The quickest route to mailbox access when your key is lost involves prying the door open. This technique requires minimal skill and basic tools like a claw hammer and a flathead screwdriver. Always secure approval from the owner or manager to prevent damage to the mailbox or surrounding ones.


  1. Insert the screwdriver opposite the hinged side.
  2. Pry until resistance is met.
  3. Introduce the claw side of the hammer into the opening.
  4. Apply swift leveraged force with the hammer.

Note: This method sheers off the lock’s tailpiece, allowing for easy removal and replacement. Ensure you have a replacement lock and address any damage to the mailbox door before installation.

2. Picking: A Practical Guide for Novices

Learn the art of picking a mailbox lock with minimal experience. Most mailbox locks utilize a pin tumbler system. Master the technique using basic tools like a tension wrench and rake. While novice-friendly, investing in quality tools enhances the speed and efficiency of the process.


  1. Place the tension wrench at the top or bottom of the keyway.
  2. Rotate the tension wrench in the direction the key turns.
  3. With light tension, insert the lock pick and manipulate it in the keyway.
  4. If unsuccessful in 60 seconds, release tension and retry.

Pro Tip: For those uninterested in lock picking as a hobby, locksmith assistance is readily available.

3. Drilling: Crafting the Overture of Access

For situations where prying takes a backseat, drilling becomes the go-to mailbox lock hack. Equipped with a screwdriver, power drill, and a new drill bit, this method ensures a symphony of destruction that grants access. Adequate preparation, including lubricating the lock and removing the dust cover, sets the stage for a smoother drilling process.


  1. Use the screwdriver to pry off the keyway dust cover.
  2. Place the drill bit at the top of the keyway.
  3. Drill until five distinct jolts signal destruction of all pin chambers.
  4. Use the screwdriver as a key to turn the lock.

Common Pitfall: Beware of drill bit breakage, as it can complicate the process. Maintain proper lubrication and avoid forcing the bit excessively.

4. Call a Locksmith: Maestro of Mailbox Liberation

For those uninterested in the intricacies of lock picking or destructive methods, locksmiths emerge as the maestros of mailbox liberation. While locksmiths possess the skill to pick a mailbox lock, they often opt for non-destructive entry through drilling and lock replacement. This ensures a seamless resolution, especially when the lock is non-rekeyable.
