Create a Bump Key to Open Any Door

Lockpicking is a skill that takes years upon years to master. Locks come in all sorts of shapes and sizes, but have common ground in how they work. Most cylinder locks have “tumblers,” which are metallic cylindrical objects that sit vertically to the actual locking mechanism. Tumblers have five or six holes with rounded key pins of various height in them, each needing to meet an exact height or the cylinder in the center (the lock itself) will not be allowed to turn. This is the reason why you see those “mountains and valleys” on keys, and why these types of locks are called pin tumbler locks. Each is unique.

Today’s Null Byte is going to demonstrate how to effectively make what is called a “bump key”. A bump key can open any lock that it fits into. It’s helpful to have in your pocket if you ever lose your keys, because it can open your door lock and your deadbolt, even if they normally require seperate keys. I keep mine in my wallet.
