Why won't my 5834-4 key fob program?
The video below will assist you with programming a 5834-4 keyfob:
In May 2015, Honeywell began shipping the 5834-4 keyfob with High Security (Encrypted) mode enabled. If encryption is not enabled, the transmission from the keyfob is the same every time you send the disarm command. But, when High Security mode is enabled, the keyfob uses a rolling code every time it sends a transmission to the alarm panel. Once the 5834-4 and the panel are synced, only the panel can predict what the next rolling code from the fob will be, thereby making arm/disarm with a wireless device much more secure. This, however, requires an extra step when programming a keyfob into the panel, and to make matters more confusing, the keyfob can be learned into the alarm panel, even if High Security mode is enabled, and they are not yet in sync, but once you exit programming, the fob will neither arm, nor disarm, until the sync has been completed. You can tell when the 5834-4 is in High Security mode when the LED, which flashes when you transmit with the fob, lights Red, instead of Green. Red = High Security Mode. Green = No Encryption. To sync the panel and the 5834-4 follow these steps:
- Enter Go-No-Go Test mode. On the Vista Panels, enter Installer Code (default is 4112) + [#] +  to put the system into the Go-No-Go Test Mode. On the Lynx Touch, go to Security->More->Tools->Installer Code->Test->Go-No-Go Test.
- Wait one minute. While in this mode, the system will beep about once every 40 seconds to remind you it's in test mode. Wait until you've heard the 2nd indication beep (we want to be sure the system is in test for at least 1 minute before proceeding).
- Sync the fob and panel. On the 5834-4, press and hold down the A, B, and C buttons until you hear a double beep from the alarm panel. This indicates the panel and the fob have been synced. Remember that the 5834-4 actually has 2 serial numbers which can be used, so if you are using them both, you will also have to press and hold down the A, B, and D buttons until you hear the double beep, to sync the panel with the second serial number.
NOTE: To exit the Go-No-Go test mode, simply enter your 4 digit code + off, or, on the LynxTouch, press Home, then enter your 4 digit code. All Lynx panels can support High Security Mode. On the Vista panels, all Keypads with built-in receivers support it, as well, but not all 5881/5882 style receivers do. You need to be sure, if you have this type of receiver, that it supports encryption, and if there is a dip switch setting that affects encryption, that it is enabled.
Follow these steps if the 5834-4 is in low security mode, but you wish to put it into high security mode.
