Safety Guidelines
  • Location, location, location! Choose a hiding spot that's inconspicuous but also accessible to *you*. Avoid obvious places like under the bed or in a drawer.

  • Make sure the glue is completely dry before handling the box to ensure the structure holds well.

Common Mistakes to Avoid

1. Poorly Concealed Location

Reason: Choosing an obvious hiding spot makes your safe easily discoverable. Obvious places like under the bed or inside a drawer are easily searched.
Solution: Select inconspicuous and unexpected locations, such as inside a hollowed-out book or behind a loose wall panel.

2. Weak or Easily Guessed Combination/Password

Reason: Using simple combinations or easily guessable passwords (like birthdays or pet names) compromises the security of your safe.
Solution: Use a complex, randomly generated combination or password, and avoid using personally identifiable information.

FAQs

What materials do I need to build a DIY spy safe?
The materials depend on your chosen design. Common options include a hollowed-out book, a repurposed electrical outlet cover, or a custom-built box. You'll likely need tools like a saw, screwdriver, glue, and possibly a lock mechanism depending on your complexity level. The guide will outline specific materials for each example.
How secure is a DIY spy safe compared to a commercially bought safe?
A DIY spy safe’s security depends entirely on your design and execution. While it won't offer the same level of protection as a high-security commercial safe, a cleverly designed and well-hidden DIY safe can deter casual thieves or curious individuals. The focus is on creative concealment and making it difficult to find, rather than impossible to open with sufficient effort.
