About this book
Every day, thousands of keys are bent, snapped, or refused by locks because someone chose the wrong key cap or installed it poorly. Key caps are a small, inexpensive component, but they determine how a key feels in the hand, how long it lasts in a pocket, and whether it seats correctly in the cylinder. This handbook treats key caps as the engineering component they are, not an afterthought. It walks through the full decision process: understanding what key caps are and why they matter, comparing materials and profiles, matching caps to key types and usage environments, and installing them so they stay put.

★★★★★I’m a locksmith and have been buying key caps for years based on whatever my supplier had in stock. This book finally lays out the actual differences between nylon and ABS, and why internal cavity design matters more than outer diameter. The chapter on installation saved me from a batch of caps that would have spun loose on brass keys. Only complaint is I wish the maintenance section had more on high-usage commercial locks, but overall a solid reference I keep in the shop.

★★★★★Picked this up because I manage a facility with about 400 keys and we’re always losing caps or dealing with keys that don’t seat right. The selecting chapter helped me standardize on one profile, and the glossary is actually useful when I talk to vendors. The business chapter surprised me, gave me a realistic view of what private labeling involves even if I’m not going that route. It’s dry in spots, but that’s what I wanted, no fluff, just specs and process.
