The Napco KH36-10 is a 10 pack of branded proximity key fobs designed for use with HID 125 kHz readers and Alarm Lock Trilogy proximity locks in professional electronic access control systems. Each key fob uses a 36 bit format that provides a very large number of possible ID codes, making it suitable for multi door facilities and growing cardholder populations. These credentials are ideal for doors, interior passages and secure areas where convenient keychain style access is preferred over full sized cards. Built on HID 125 kHz proximity technology, the KH36-10 fobs integrate with many existing proximity readers and Trilogy locks that accept Napco branded 36 bit credentials. Installers can enroll the fobs directly at the lock, through optional Trilogy management software or by using dedicated enrollment tools, which simplifies deployment on new projects and retrofits. This flexibility makes the KH36-10 a practical choice for small businesses, schools, healthcare facilities and multi tenant buildings that want to standardize on key fob credentials instead of or alongside cards. Each proximity fob features a compact housing with a key ring hole so users can keep it on everyday keychains. The shell is constructed with an ultrasonically welded ABS body and TPE insert to provide durability against drops, moisture and heavy daily use. Supplied as a pre encoded 10 pack, Napco KH36-10 fobs give dealers and integrators a ready to install credential option that pairs cleanly with Trilogy locks and compatible HID 125 kHz readers for reliable, convenient access control in a wide range of security applications.
