Surety is a DIY Alarm.com service provider. Are you referring to controlling a garage via an Alarm.com account and a Z-wave garage controller or MyQ, etc?

It sounds like you are referring to the overhead internal functions and fob controls. For assistance with the garage door, be sure to reach out to the manufacturer for support.
