Notes for clients
These articles are for homeowners, property managers, and facility leads who want a plain explanation of hardware and building codes. Each note is one decision, such as a rekey, a closer size, or a panic device. We update them when a product or a code reference changes.

Frequent questions
What are the field notes about?
One hardware decision each: a rekey, a closer size, a panic device, a restricted key, a strike, or a safe label.
Are the notes neighborhood ads?
No. They explain the hardware. The service-area list is a different page.
