Enhance your door's security and convenience with a Main Door Lock One-Side Key that features key access on one side and an interior knob on the other. This lock is designed for both residential and commercial use, providing a secure and stylish solution for various door types.

The single-sided design means that the lock is visible only on the interior side of the door, with a thumb turn or knob, while the exterior side remains key-access only. This configuration prevents unauthorized access from the outside, as there is no external cylinder or keyhole.
