The Alarm Lock KH36-10 36-Bit Key Fob is a compact and reliable access control credential designed for use with Alarm Lock Systems, Inc. and NAPCO Security Technologies platforms. Operating on proven 125 kHz proximity technology, this key fob is programmed in a 36-bit format, providing expanded credential capacity compared to standard 26-bit formats. This increased bit structure allows for a larger pool of unique card numbers, making it ideal for systems that require scalable user management across multiple users or locations.

The 36-bit format offers a more structured credential system while maintaining compatibility with HID 125 kHz readers commonly used in Alarm Lock and NAPCO environments. Each key fob is pre-encoded for immediate deployment, simplifying system enrollment and reducing setup time. Its durable, compact design makes it perfect for everyday use on keyrings or lanyards, providing convenient, contactless access for employees, tenants, and authorized users. Supplied in a 10-pack, the KH36-10 is a dependable solution for system expansions, replacements, or new installations where format consistency and reliable performance are essential.
