I am not sure if this is the same problem, but I had an issue when the arm/disarm button was used, the alarm world set, then immediately unset. The doors would like, then unlock.
It turned out that the arm/disarm button was sticking. The carbon coated membrane within the key fog has a lot of "pocket lint". I cleaned the membrane and it has worked since. The membrane switch is similiar to any modern day TV remote control or even game controllers.

I am experiencing a frequent and re-occurring problem with my remote control. I will go several days where my master key will engage & dis-engage both the security system & door locks. Then for no reason it won't work for a time period, only to resume normal operation again. It is very frustrating. Any comment or suggestions would be appreciated.
