Keyed-Alike Security

The Master Lock 21KALJ-10L102 is a rectangular steel padlock designed for users who need multiple locks opened by a single key. Its five-pin cylinder and laminated body provide high-security mechanical locking for gates, sheds or storage units. The keyed-alike configuration simplifies key management for property managers or households.

Steel Build and Fixed Shackle

A 1-3/4 in wide laminated steel body encloses the mechanism while a 5/16 in diameter steel shackle offers 2 1/2 in of vertical clearance and 3/4 in of horizontal space. The shackle is not removable, so the lock must be slipped over a hasp or chain link during installation. Two bumpers protect the body finish from impact during daily use.

Mechanical Limits and Rekeying

The lock operates solely with the supplied K27 keyway cut to code 10L102; no electronic or combination override exists. Lost keys require a locksmith or the original code for duplication because control-key registration is not required. The cylinder is rekeyable, allowing a professional to change the pinning if a key is compromised.
