On my Smartcode Touchscreen, The lock beeps, the Checkmark and Lock symbols alternate flashing, and the door cannot lock

7 possible reasons:
  1. The door handing process was not executed during installation. Perform the manual door handing process in the Installation Guide.
    Perform the manual door handing process
    If needed, the door handing process can be initiated manually. This is useful if the lock is being moved to a different door
    • Remove battery pack.
    • Press and HOLD the Program button while reinserting the battery pack. Release button once battery pack is installed. The status LED will flash red and green.
    • Press the Program button once more.
    • The latch bolt will extend and retract to learn the orientation of the door. Success: flashing checkmark symbol and single column of digits. Failure: flashing “X” pattern
  2. The wrong deadbolt latch is installed.
    SmartCode deadbolts require a tapered latch bolt for ease of operation. If the latch being used is from an older lock, it will likely not have a tapered latch bolt. Remove the lock from the door, including the old latch. Replace with the new tapered latch that came with the lock and reinstall the lock.
  3. The deadbolt latch and strike are misaligned, causing the latch to bind.
    Adjust the tab of the lower strike (for your knob or lever) to help align the upper latch and strike so that the latch bolt enters the strike when the door is locked.
  4. The lower latch and lower strike (for your knob or lever) are misaligned, putting too much load on the deadbolt latch.
    As a test, rotate the turnpiece on the deadbolt so the latch is retracted (unlocked), and close the door. If you have to push, pull or lift the door to get it to close, adjust the position of the lower strike.
  5. The hole in the door frame for the latch bolt is not drilled deep enough. Make sure the hole in the door frame is drilled at least 1” (25 mm) deep.
  6. The mounting plate is placing tension on the torque blade. Attempt to lock and unlock the door with the key. If it is unable to rotate, remove the interior assembly from the mounting plate. Test the key again. If it is still unable to rotate, loosen the screws on the mounting plate and reposition the plate so there is no tension on the cylinder torque blade. Make sure the latch bolt can operate smoothly with the key and reinstall the interior assembly.
  7. The clutch is disengaged. Remove the battery pack. Remove the interior assembly from the door. Verify that the lock can be operated smoothly with the key while the interior is removed. Attempt to rotate the turnpiece on the interior assembly to the vertical position. If it cannot rotate to the vertical position, the clutch has become disengaged.
    Place the battery cover onto the interior assembly, making sure to align the turnpiece with the shaft. Rotate the turnpiece 180° clockwise (you will need to use force when rotating the turnpiece, and you will hear it click). This will re-engage the clutch.
    Align the turnpiece with the torque blade and reinstall the interior assembly on the door.
