- To Unlock from Exterior: Insert the key into the cylinder and turn it in the opposite direction until the knob is unlocked. The knob will then turn freely.
- To Lock from Interior: Rotate the turn piece located on the inside knob. The knob will then be locked.
- To Unlock from Interior: Rotate the turn piece back to its original position. The knob will then be unlocked.
- To Open the Door: Once unlocked, turn the knob in either direction to retract the latch bolt and open the door.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your Weiser CLC10053 Tell KT2100 Series Entry Knobset.
- Cleaning: Clean the knobset surfaces with a soft, damp cloth. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish.
- Lubrication: Periodically apply a small amount of graphite lubricant or a silicone-based spray lubricant to the keyway and the latch mechanism. Do not use oil-based lubricants, as they can attract dirt and dust.
- Screw Tightness: Periodically check all mounting screws and latch screws for tightness. Tighten any loose screws to prevent wobbling or misalignment.
- Key Care: Keep keys clean and free of debris. Do not force a key if it feels stiff; apply lubricant to the keyway first.
