TeacherLock FAQs

YES. From the occupancy side, if the door swings inwardly, the user will need a flush mount strike kit. If the door swings outwardly toward the hall, then the standard kit will work.

YES. From the occupancy side, if the door handle is on the left, we call this a left-hand opening door. For customer convenience, we configure the TeacherLock™️ classroom for left or right hand for the user so they don't have to do it in the field.

IF the double door has a hollow support in between the doors, then in most cases, yes, TeacherLock™️ classroom door locks will work. If the double doors do not have a support (door jamb) in between then, unfortunately, these lockdown door locks are not a proper solution. We are excited to be working on a new product which will be released in the future to accommodate this. Stay tuned!

YES. Which is why we recommend ordering a few extra activators for substitute teachers, etc. It is also strongly advised to maintain an inventory of activators and tight control over their use and distribution.

YES. It is highly recommended to keep a tight control over this key. Typically, it is best to have one for emergency responders, one for administrators, and one for facilities.
