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.
1. Anatomy
Flat spring-loaded wafers sit in the plug and poke up across the shear line into the housing — that overhang blocks rotation. Each wafer protrudes a different amount (its bitting). Labels shown.
How it works
Flat spring-loaded wafers stick out into the shear line and block the plug. The correct key brings each wafer to the shear line — in a single-sided lock that means pulling it flush with the plug's edge; in a double-sided lock it means centering the wafer so neither tab crosses the shear line. 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.
