What is a "key fob" used for in alarm systems?

A key fob is primarily a handheld device designed for convenience in the operation of alarm systems, allowing users to remotely arm or disarm the system without the need to enter a code on a keypad. This enhances user accessibility and speeds up the process of securing or disarming a property, as users can simply press a button to perform these functions from a distance. The design is user-friendly, often incorporating buttons that are easy to press, and they are typically compact enough to be conveniently carried on a keychain.

This functionality makes key fobs a popular choice in modern alarm systems, as they improve the overall user experience by providing a quick and efficient means of managing security.
