A common mistake diyers make while using there Honeywell LYNX Touch L5100 wireless security system is they access the programming mode and end up locking themselves out when done. This occurs because when exiting programming mode the system will always ask you if you would like the installer to access programming mode again. Typically you are suppose to say yes and than back out. Some people tend to rush through programming and end up saying no. This will not allow you to get back into programming mode. Well this video will show you how you can correct this issue.
As the video shows you want to make sure your system’s back up battery is unplugged. Once this has been completed you than want to unplug the transformer for a few seconds. Go ahead an plug the transformer back into the outlet. The system will go through a start up procedure this is normal. Once the system loads you will see the red standby notice at the top of the screen. At the time you see this hold down the unlock key for three seconds, once the system begins beeping hold down the unlock key for an additional 3 seconds you will notice the digital keypad pops up. From this point you will enter clear 0,0 at this point your system will take you to the area where you enter programming. Now you should be able to select program if it has let you do this you have completed to the process successfully! Just make sure anytime in the future when leaving programming mode that you always say yes to allow installer back into programming!
