Wafer Lock
If you're brand new to locksport, start here. Wafer locks are everywhere — cabinets, mailboxes, older cars — and their loose tolerances make them very forgiving.
At rest
Flat spring-loaded wafers poke up out of the plug and cross the shear line into the housing — that overhang blocks rotation. Each wafer protrudes a different amount (its bitting).
How it works
Flat spring-loaded wafers stick out into the shear line and block the plug. The correct key pulls each wafer flush with the plug's outer edge. Wafer locks usually have 4-8 wafers, and many are double-sided — wafers protrude both up and down (cabinets and older cars).
Tools you need
A hook pick and tension wrench (lighter pressure than a pin tumbler), rakes, jiggler / try-out keys, or keyway-specific Lishi decoders for automotive wafers.
Step-by-step technique
- Single-pin pick each wafer to the shear line with very light tension, or
- Rake with minimal tension — many wafer locks pop on the first or second pass, or
- Insert a jiggler key, apply light tension and jiggle; budget locks often yield in seconds.
Common mistakes
The main mistake is over-tensioning. Wafers need a light touch — much lighter than a pin tumbler.
Skill level & notes
Low security overall — loose tolerances and few possible combinations. The perfect first lock to learn on.
