CompX D500-KY Timberline Removable Lock Plug Change Tool

The CompX D500-KY is the dedicated plug change tool (also called a change key) for CompX Timberline Removable Lock Plug systems. Designed specifically to remove and swap lock plugs without disassembling the entire lock body, this tool is the correct instrument for facilities managers, locksmiths, and maintenance technicians who manage cabinet lock keying in commercial, industrial, or institutional environments.

This key is engineered to work with all CompX Timberline plugs carrying key codes ending in TA. If your Timberline lock plugs use the TA key code suffix, the D500-KY is the correct change tool for your application.

What Is a Removable Lock Plug Change Tool?

CompX Timberline locks feature a removable plug design that allows a technician to swap out one keyed plug for another — effectively re-keying the lock or rotating plugs between keyways — without removing the lock from the cabinet or furniture. The D500-KY change tool (change key) is inserted into the lock cylinder to release and extract the plug, enabling fast, tool-efficient re-keying in the field. This is especially useful in master-key environments, high-turnover facilities, or any setting where keying flexibility is a priority.
