I am trying to reprogram a Merlin Legend 7 system from key mode to hybrid, but the system beeps when I try to change it. I pulled the controller module out, and it appears the switches are set to put it in permanent key mode. Can I just move the switches back to the other position so I can change the mode to hybrid? How "permanent" is permanent key mode? Changing the switches won't permanently disable the system or anything will it? Thanks.
