This video will show you how to reset the master code in the Honeywell LYNX Touch L5210 wireless security system.

To reset the master code on the Honeywell L5210 from the home screen select security, more, tools, installer code "default is 4112", program, scroll down, reset master code, select yes to reset, back out to the home screen. Now to verify your master code is now working from the home screen select security, more, tools, enter the default master code which is 1234, this should allow you back into the the master code programming guide. 

We recommend changing the Honeywell L5210 master code from default because this code is needed in order to add, delete and change other user codes. Also, the master code can be used to arm and disarm the system even if the system was not armed using that code so you never want to give anyone your master code. When entering the master code into your Honeywell LYNX Touch L5210 wireless security system it takes you to a specific menu. In this menu you can change user codes, view event history, change the date and time, create a visual slide show and configure the WIFI settings.
