What's the Difference Between ADT Key Fobs & Honeywell 5834-4

There is no difference between an ADT Key Fob and a Honeywell 5834-4. They are the same device. ADT simply rebranded the 5834-4 so that they could offer customers their own "in-house" version. This means that an ADT Key Fob can be used in exactly the same manner as any Honeywell 5834-4.


To best understand an ADT Key Fob, one should simply understand a Honeywell 5834-4. The Honeywell 5834-4 is technically a sensor from the Honeywell 5800 Series. It is a unidirectional sensor that communicates at a frequency of 345 MHz. It offers an encryption mode, and it can be programmed with multiple security panels if desired. Because of this, a user can easily bring a 5834-4 to a new monitoring company and alarm system, without having to delete the device from their old ADT setup. This makes the device incredibly versatile and easy to use.

The wireless communication frequency of the ADT Key Fob and the Honeywell 5834-4 allows these devices to interface with a wide variety of different security panels. The 345 MHz frequency is used by many different panels, including the Honeywell Lyric Controller, Honeywell LYNX Touch Panels, Honeywell VISTA Systems, the 2GIG GC3 and the 2GIG GC2. But remember, the key fob must be enrolled with the panel before it will serve any function.

Each button on a key fob is assigned to its own zone on the system. Most users set up each button to perform a unique action. Some common actions for a key fob zone include arming away, arming stay, disarming and a police panic. It is also possible to press multiple buttons simultaneously in order to have the system perform an entirely different action from single button presses. These multiple button presses will also need to be programmed with the system. Up to eight unique actions can be performed using a 5834-4 Key Fob on a single alarm system.
