TUBULAR LOCKS DEFINED AND DESCRIBED
They just look odd. Tubular locks, with their weird round keyways, don't even look like lock cylinders to most people and they also look intimidating. Try to pick one with a regular lock pick and you'll probably have a great time getting nowhere. That's why they make special lock picks to deal with them.
But how do they work? How DO you pick one? This compact book, with its 40 pages, does a great job covering the subject. It shines a light on the innermost workings of these odd, cryptic lock cylinders.
