PinningLab: Locksmith Charts

Calculate, validate, visualize, and document lock-cylinder pin stacks — fully offline, on your bench. PinningLab is a working tool for licensed locksmiths, institutional locksmiths, door-hardware technicians, and supervised apprentices. Enter the key bittings you already possess, pick the exact cylinder profile, and get a validated chamber-by-chamber pin chart with a visual cross-section of every stack. CALCULATE • SFIC A2 pinning with control shear line, build-up pins, and total-stack rule • Conventional cylinders: single key, keyed-alike, and explicit multi-key charts • 5, 6, or 7 chambers with fast spreadsheet-style entry and paste support • Define your own conventional profiles, verified by your own test fixture VALIDATE • Depth range, MACS, control collisions, and pin-kit checks before you load pins • Blocking errors point at the exact chamber — nothing is rounded or substituted • Every bundled profile cites its manufacturer source document, revision, and pages, visible in the app DOCUMENT • Chamber tables, visual pin-stack diagrams, and a complete pin tally • Job worksheets as PDF or CSV, with an optional redacted mode • Encrypted job history on this device — nothing ever leaves it PRIVATE BY DESIGN • No account, no ads, no analytics, no network access • AES-encrypted storage with optional Face ID / Touch ID app lock • App-switcher privacy overlay and screen-capture protection PinningLab calculates from bittings you already have for locks you are authorized to service. It does not decode keys from photos, generate key combinations or master-key systems, or teach bypass techniques. Verify every chart against the current manufacturer procedure before loading a core.
