  10. Final mechanical and fitment check:
    It is important to ensure the fitment and mechanical operation of the lock is working correctly
    • With the door in the open position manually exercise the thumb turn, levers and cylinder (if applicable) and ensure all are moving smoothly (without binding, grinding or resistance) and are correctly actuating the lock in each case (levers retracting the latch, cylinder and thumb turn locking and unlocking correctly, etc.).
    • Ensure the door closes and opens smoothly. Shimming or adjusting the door or any components (weather-stripping, door closing mechanisms, etc.) that may be impeding proper door motion and operation is critical to the longevity and proper functionality of all door and hardware components.
    • Ensure the door closes, latches and locks smoothly and properly. Perform the same manual operational checks as in step (a). The lock should feel and function the same in both the open and closed positions.
    • Once confirming your successful installation, please review the ML2 Programming Instructions to complete the lock setup process.
