Basic Functionality:

Opening the Lock

Residents can open the lock on any door to which they are authorized by simply inserting the card into the slot at the top of the lock and entering a 4-digit PIN. A green light after inserting the card indicates a PIN is not required, while a green AND red light indicates a PIN is required.

Securing the Lock

The lock will automatically secure itself after you successfully open the lock.

Advanced Functionality:

"Double-Dipping" the Lock

Double-dipping the lock is a term often used to refer to the function of swiping the card twice, consecutively, into the slot of the lock. Double-dipping the lock puts the lock into a mode where it will remain unlocked indefintely. After double-dipping the lock, a briefly flashing green light indicates the door is in an unlocked mode. To resecure the lock, you simply need to double-dip it again.

Deadbolting the Lock from Inside

The locks can be deadbolted for additional security, similar to throwing the deadbolt on traditional locks. Most locks are opened by turning the knob toward the hinged side of the door or pushing the lever down (in the case of level handles), but by simply turning the knob in the opposite direction, toward the frame, or pulling the lever up (in the case of lever handles), the built-in deadbolt of the lock is engaged.

Deadbolting the Lock from Outside

The TESA Locks can also be deadbolted from the exterior for additional security, similar to throwing the deadbolt from outside with a traditional hard key. Simply close the door, insert the card key, enter the PIN and pull the lever upward.
